{
    CustomAlertView *alertView = [self switchCitiesAlert];
    alertView.layer.cornerRadius = 3;
    alertView.titleLabel.font = [UIFont boldSystemFontOfSize:18];
    alertView.messageLabel.textColor = [UIColor blackColor];
    alertView.messageLabel.font = [UIFont fontWithName:@"pingFangSC-light" size:16];
    
    CustomAlertButton *cancelButton = [CustomAlertButton buttonWithTitle:@"取消" handler:^(CustomAlertButton *button) {
        NSLog(@"点击了取消按钮：%@",button.currentTitle);
    }];
    
    __weak typeof(self) weakSelf = self;
    CustomAlertButton *okButton = [CustomAlertButton buttonWithTitle:@"确定" handler:^(CustomAlertButton * button) {
        [weakSelf.switchCitiesStyle dismiss];
    }];
    
    cancelButton.lineColor = [UIColor colorWithHex:@"0x70AFCE"];
    okButton.lineColor = [UIColor colorWithHex:@"0x70AFCE"];
    [cancelButton setTitleColor:[UIColor colorWithHex:@"0x70AFCE"] forState:UIControlStateNormal];
    [okButton setTitleColor:[UIColor colorWithHex:@"0x70AFCE"] forState:UIControlStateNormal];
    cancelButton.edgeInsets = UIEdgeInsetsMake(22, 0, 0, 0);
    
    [alertView adjoinWithLeftAction:cancelButton rightAction:okButton];
    
    return alertView;
}

创建垂直提示框

- (CustomAlertView *)createVerticalAlertView
{
    ......
    [alertView addAlertButton:cancelButton];
    [alertView addAlertButton:submitButton];
    [alertView addAlertButton:okButton];
    
    return alertView;
}

4、提示框按钮的实现

{
    if (self = [super init])
    {
        self.buttonClickedBlock = handler;
        
        self.titleLabel.font = [UIFont systemFontOfSize:17];
        self.titleLabel.adjustsFontSizeToFitWidth = YES;
        [self setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [self setTitleColor:[UIColor darkGrayColor] forState:UIControlStateHighlighted];
        [self setTitle:title forState:UIControlStateNormal];
        [self addTarget:self action:@selector(handlerClicked) forControlEvents:UIControlEventTouchUpInside];
        
        _horizontalLine = [CALayer layer];
        _horizontalLine.backgroundColor = [UIColor colorWithHex:@"bfbfbf"].CGColor;
        [self.layer addSublayer:_horizontalLine];
        
        _verticalLine = [CALayer layer];
        _verticalLine.backgroundColor = [UIColor colorWithHex:@"bfbfbf"].CGColor;
        [self.layer addSublayer:_verticalLine];
    }
    return self;
}

b、点击按钮的回调

- (void)handlerClicked
{
    if (self && self.buttonClickedBlock)
    {
        self.buttonClickedBlock(self);
    }
}

c、线条宽度可配置

{
    [super layoutSubviews];
    
    CGFloat lineWidth = self.lineWidth > 0 ? self.lineWidth : 1 / [UIScreen mainScreen].scale;
    _horizontalLine.frame = CGRectMake(0, 0, self.width, lineWidth);
    _verticalLine.frame = CGRectMake(0, 0, lineWidth, self.height);
}

d、线条颜色可配置

- (void)setLineColor:(UIColor *)lineColor

        self.clipsToBounds = NO;
        
        // 子视图按钮的高度，默认49
        self.subOverflyButtonHeight = 49;
        
        // 默认宽度200
        _contentSize.width = 200;
        if (constantWidth > 0) _contentSize.width = constantWidth;
        
        
        _paddingTop = 15; _paddingBottom = 15; _paddingLeft = 20; _spacing = 15;
        
        if (title.length)
        {
            _titleLabel = [[UILabel alloc] init];
            _titleLabel.text = title;

            NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:message];
            NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
            paragraphStyle.lineSpacing = 5;
            [string addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, message.length)];
            _messageLabel.attributedText = string;

            _messageLabel.size = [_messageLabel sizeThatFits:CGSizeMake(_contentSize.width - 2 * _paddingLeft, MAXFLOAT)];
            _messageLabel.y = _titleLabel.bottom + _spacing;
            _messageLabel.centerX = _contentSize.width / 2;
            _contentSize.height = _messageLabel.bottom;
        }
     
        self.size = CGSizeMake(_contentSize.width, _contentSize.height + _paddingBottom);
        if (!title.length && !message.length)
        {
            self.size = CGSizeZero;
        }
    }
    return self;

            layout(lastAlertButton.bottom + alertButton.edgeInsets.top);
        }
    }
    else// first
    {
        // 增加10间距
        layout(_contentSize.height + alertButton.edgeInsets.top + 10);
    }
    
    alertButton.verticalLine.hidden = YES;
    [self insertSubview:alertButton atIndex:0];
    self.size = CGSizeMake(_contentSize.width, alertButton.bottom + alertButton.edgeInsets.bottom);
    objc_setAssociatedObject(self, AlertViewActionKey, alertButton, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

- (void)addOverflyButton:(OverflyButton *)button;

/// 水平方向两个并列按钮
- (void)adjoinWithLeftOverflyButton:(OverflyButton *)leftButton rightOverflyButton:(OverflyButton *)rightButton;

@end

4、实现接口方法

a、初始化方法

- (instancetype)initWithFlyImage:(UIImage *)flyImage
                     highlyRatio:(CGFloat)highlyRatio
                 attributedTitle:(NSAttributedString *)attributedTitle
               attributedMessage:(NSAttributedString *)attributedMessage
                   constantWidth:(CGFloat)constantWidth
{
    if (self = [super init])
    {
        self.backgroundColor = [UIColor whiteColor];
        self.width = constantWidth;// 视图宽度
        self.highlyRatio = highlyRatio;// 顶部图片透明区域所占比
        // 消息文本边缘留白，默认UIEdgeInsetsMake(15, 15, 15, 15)
        self.messageEdgeInsets = UIEdgeInsetsMake(15, 15, 15, 15);
        // 子视图按钮(OverflyButton)的高度，默认49
        self.subOverflyButtonHeight = 49;
        // 可视滚动区域高，默认200(当message文本内容高度小于200时，则可视滚动区域等于文本内容高度)
        self.visualScrollableHight = 200;
        
        // 创建子视图
        [self createSubviews];
        
        _flyImageView.image = flyImage;
        _titleLabel.attributedText = attributedTitle;
        _messageLabel.attributedText = attributedMessage;
        
        // 创建子视图的约束
        [self createSubviewConstraints];
    }
    return self;
}

b、水平方向两个并列按钮

- (void)adjoinWithLeftOverflyButton:(OverflyButton *)leftButton rightOverflyButton:(OverflyButton *)rightButton
{
    // 清除按钮
    [self clearOverflyButtons:self.adjoinOverflyButtons.allObjects];
    objc_setAssociatedObject(self, OverflyViewActionKey, nil, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
    
    // 左边按钮的尺寸
    leftButton.size = CGSizeMake(self.overflyViewSize.width / 2, self.subOverflyButtonHeight);
    leftButton.y = self.overflyViewSize.height;// 容器尺寸
    
    // 右边按钮的尺寸
    rightButton.frame = leftButton.frame;
    rightButton.x = leftButton.right;
    
    // 显示中间垂线
    rightButton.verticalLine.hidden = NO;
    
    // 添加按钮
    [self addSubview:leftButton];
    [self addSubview:rightButton];
    self.adjoinOverflyButtons = [NSMutableSet setWithObjects:leftButton, rightButton, nil];
    
    // 重新计算容器尺寸
    self.size = CGSizeMake(self.overflyViewSize.width, leftButton.bottom);
}

c、可增加多个按钮依次向下排列

- (void)addOverflyButton:(OverflyButton *)button
{
    // 清除按钮
    [self clearOverflyButtons:self.adjoinOverflyButtons.allObjects];
    [self.adjoinOverflyButtons removeAllObjects];

    void (^layout)(CGFloat) = ^(CGFloat top){
        // 子视图按钮(OverflyButton)的宽度
        CGFloat width = self.overflyViewSize.width - button.flyEdgeInsets.left - button.flyEdgeInsets.right;
        // 子视图按钮(OverflyButton)的高度，默认49
        button.size = CGSizeMake(width, self.subOverflyButtonHeight);
        button.y = top;
        // 中心位置
        button.centerX = self.overflyViewSize.width / 2;
    };
    
    OverflyButton *lastButton = objc_getAssociatedObject(self, OverflyViewActionKey);
    if (lastButton)// current
    {
        if (![button isEqual:lastButton])
        {
            // 添加新的Button到上一个Button的底部
            layout(lastButton.bottom + button.flyEdgeInsets.top);
        }
    }
    else// first
    {
        layout(self.overflyViewSize.height + button.flyEdgeInsets.top);
    }
    
    button.verticalLine.hidden = YES;// 隐藏中间垂线
    [self insertSubview:button atIndex:0];// 插入按钮到顶层
    
    // 重新计算容器尺寸
    self.size = CGSizeMake(self.overflyViewSize.width, button.bottom + button.flyEdgeInsets.bottom);
    
    // 保存作为上一个按钮
    objc_setAssociatedObject(self, OverflyViewActionKey, button, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

    if (!cell)
    {
        cell = [[WallCollectionView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"WallCollectionView" layout:[self layout] appearance:[self appearance]];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
    }
    cell.wallView = self;
    cell.rowIndex = indexPath.row;
    id object = [_models objectAtIndex:indexPath.row];
    if ([object isKindOfClass:[NSArray class]])
    {
        cell.models = (NSArray *)object;
    }
    return cell;
}

WallViewDelegateConfig配置布局和外观

配置布局

- (WallViewLayout *)layout
{
    id <WallViewDelegateConfig> config = (id <WallViewDelegateConfig>)self.delegate;
    
    if ([config respondsToSelector:@selector(layoutOfItemInWallView:)])
    {
        return [config layoutOfItemInWallView:self];
    }
    return [[WallViewLayout alloc] init];
}

配置外观

- (WallViewAppearance *)appearance
{
    id <WallViewDelegateConfig> config = (id <WallViewDelegateConfig> )self.delegate;
    
    if ([config respondsToSelector:@selector(appearanceOfItemInWallView:)])
    {
        return [config appearanceOfItemInWallView:self];
    }

轮播图

1、运行效果

轮播图.gif

2、轮播图的使用方式

// 创建轮播图
- (void)createAutoScrollView
{
    self.autoScrollView = [[AutoScrollView alloc] initWithFrame:CGRectZero];
    
    NSMutableArray *scrollImages = [[NSMutableArray alloc] init];
    UIImage *boy = [UIImage imageNamed:@"稚气.PNG"];
    UIImage *coffee = [UIImage imageNamed:@"咖啡.JPG"];
    UIImage *luckcoffee = [UIImage imageNamed:@"luckcoffee.JPG"];
    [scrollImages addObject:boy];
    [scrollImages addObject:coffee];
    [scrollImages addObject:luckcoffee];
    self.autoScrollView.scrollImage = [NSMutableArray arrayWithArray:[scrollImages copy]];
    
    self.autoScrollView.duration = 3;
    self.autoScrollView.backgroundColor = [UIColor redColor];
    self.autoScrollView.scrollSize = CGSizeMake(self.view.frame.size.width, 200);
    
    [self.view addSubview:self.autoScrollView];
    [self.autoScrollView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.right.equalTo(self.view);
        make.centerY.equalTo(self.view);
        make.height.equalTo(@200);
    }];
}

3、提供的接口

@interface AutoScrollView : UIView

/** 滚动的图片 */
@property (nonatomic, strong, readwrite) NSMutableArray *scrollImage;
/** 滚动视图的尺寸 */
@property (nonatomic, assign, readwrite) CGSize scrollSize;
/** 滚动时长 */
@property (nonatomic, assign, readwrite) CGFloat duration;
/** 页面 */
@property (nonatomic, strong, readonly) UIPageControl *pageView;
/** 计时器 */
@property (nonatomic, strong) NSTimer *timer;

@end

4、配置轮播图

a、创建滚动视图

- (void)createSubViews
{
    // 创建滚动的方框视图
    self.scrollBox = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.scrollSize.width, self.scrollSize.height)];
    [self addSubview:self.scrollBox];
    
    // 创建滚动视图
    self.autoScrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, self.scrollSize.width, self.scrollSize.height)];
    self.autoScrollView.pagingEnabled = YES;// 能翻页
    self.autoScrollView.scrollEnabled = YES;// 能滚动
    self.autoScrollView.showsHorizontalScrollIndicator = NO;// 不显示水平滚动条
    self.autoScrollView.showsVerticalScrollIndicator = NO;// 不显示垂直滚动条
    self.autoScrollView.minimumZoomScale = 0.5;// 缩放
    self.autoScrollView.maximumZoomScale = 2.0;// 放大
    self.autoScrollView.delegate = self;// 委托
    self.autoScrollView.backgroundColor = UIColor.whiteColor;// 白色
    self.autoScrollView.userInteractionEnabled = YES;// 可交互翻页
    
    // 添加到方框视图中
    [self.scrollBox addSubview:self.autoScrollView];
    
    // 滚动视图内容范围为3倍方框视图的宽度
    CGSize viewSize = self.scrollBox.bounds.size;
    self.autoScrollView.contentSize = CGSizeMake(3 * viewSize.width, viewSize.height);
    
    // 添加图片子视图
    for (int i = 0; i < self.scrollImage.count;i++)
    {
        // 创建图片视图
        UIImageView *imageView = [self addViewToScrollView:i * viewSize.width];
        // 添加图片
        imageView.image = self.scrollImage[(i-1) % self.scrollImage.count];
        // 填充模式
        imageView.contentMode = UIViewContentModeScaleAspectFit;
    }
    // 初始化时候的偏移量
    [self.autoScrollView setContentOffset:CGPointMake(viewSize.width, 0)];
    
    // 翻页视图
    self.pageView = [[UIPageControl alloc]initWithFrame:CGRectZero];
    self.pageView.numberOfPages = self.scrollImage.count;// 页数
    self.pageView.currentPageIndicatorTintColor = [UIColor greenColor];// 页指示器颜色为绿色
    self.pageView.userInteractionEnabled = NO;// 不可点击交互
    [self addSubview:self.pageView];
    [self.pageView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.bottom.equalTo(self.autoScrollView.mas_safeAreaLayoutGuideBottom).offset(-20);
        make.height.equalTo(@44);
        make.left.equalTo(self.mas_left);
        make.right.equalTo(self.mas_right);
    }];
}

添加图片子视图到滚动视图中

- (UIImageView *)addViewToScrollView : (CGFloat)offsetX
{
    CGSize viewSize = self.scrollBox.bounds.size;
    UIImageView *view = [[UIImageView alloc] initWithFrame:CGRectMake(offsetX, 0, viewSize.width, viewSize.height)];
    [self.autoScrollView addSubview:view];
    return view;
}

b、UIScrollViewDelegate

// 开始拖动的时候停止定时器
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView
{
    [self.timer setFireDate:[NSDate distantFuture]];
}

// 滚动了重新计算索引位置
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    [self reloadIndex];
}

// 结束拖动的时候调用
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    self.pageView.currentPage = self.index;// 设置当前页面
    [self.timer setFireDate:[NSDate dateWithTimeIntervalSinceNow:self.duration]];// 重新启动定时器
}

c、设置属性

// 设置滚动视图大小
- (void)setScrollSize:(CGSize)scrollSize
{
    _scrollSize = scrollSize;
    
    // 判断变量状态，初始化数据
    [self preAction];
    // 创建视图
    [self createSubViews];
}

// 设置定时器
- (void)setDuration:(CGFloat)duration
{
    _duration = duration;
    
    if (duration > 0.0)
    {
        self.timer = [NSTimer scheduledTimerWithTimeInterval:duration target:self selector:@selector(changeNext) userInfo:nil repeats:YES];
        [self.timer setFireDate:[NSDate dateWithTimeIntervalSinceNow:duration]];
    }
}

// 设置位置
- (void)setIndex:(NSInteger)index
{
    _index = index;
    
    // 重新给图片视图赋值
    [self recreate];
}

d、滚动过程中需要用到的方法

判断变量状态，初始化数据

- (void)preAction
{
    // 尺寸
    if (self.scrollSize.width == 0 || self.scrollSize.height == 0)
    {
        self.scrollSize = CGSizeMake(300, 200);
    }
    
    // 从0开始
    self.index = 0;
}

定时滚动函数

- (void)changeNext
{
    // 设置2倍偏移量进行翻页
    [self.autoScrollView setContentOffset:CGPointMake(2 * CGRectGetWidth(self.autoScrollView.bounds), 0) animated:YES];
}

重新给图片视图赋值

- (void)recreate
{
    if (self.scrollImage && self.scrollImage.count > 0)
    {
        NSInteger totalCount = self.scrollImage.count;// 图片数量
        NSInteger leftIndex = (self.index + totalCount - 1) % totalCount;
        NSInteger rightIndex = (self.index +  1) % totalCount;
        
        NSArray <UIImageView *> *subviews = self.autoScrollView.subviews;
        subviews[0].image = self.scrollImage[leftIndex];// 上一张图
        subviews[1].image = self.scrollImage[self.index];// 当前图
        subviews[2].image = self.scrollImage[rightIndex];// 下一张图
    }

    // 每次滑动完，再滑动回中心
    [self scrollCenter];
}

每次滑动完，再滑动回中心

- (void)scrollCenter
{
    // 设置偏移量
    [self.autoScrollView setContentOffset:CGPointMake(self.scrollBox.bounds.size.width, 0)];
    // 当前页
    self.pageView.currentPage = self.index;
}

计算页数

- (void)reloadIndex
{
    if (self.scrollImage && self.scrollImage.count > 0)
    {
        CGFloat pointX = self.autoScrollView.contentOffset.x;
        
        // 此处的value用于边缘判断，当imageview距离两边间距小于1时，触发偏移
        CGFloat value = 0.2f;
        
        if (pointX > CGRectGetWidth(self.autoScrollView.bounds) * 2 - value)
        {
            self.index = (self.index + 1) % self.scrollImage.count;
        }
        else if (pointX < value)
        {
            self.index = (self.index + self.scrollImage.count - 1) % self.scrollImage.count;
        }
    }
}

1、运行效果

2020-09-28 14:15:35.388930+0800 FunctionCodeBlockDemo[30440:19511223] 点击确定按钮后，执行block回调
2020-09-28 14:15:35.389335+0800 FunctionCodeBlockDemo[30440:19511223] 选择的日期为：2020-09

日期选择器

2、选择器的使用方式

@implementation DatePickerViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    [DatePickerSubview showDatePickerWithTitle:@"日期选择器" minDateString:@"2019-08" resultBlock:^(NSString *selectValue) {
        NSLog(@"选择的日期为：%@",selectValue);
    }];
}

@end

3、提供的接口

a、DatePickerSuperView

@interface DatePickerSuperView : UIView

// 属性
@property (nonatomic, strong) UIView *backgroundView;// 背景蒙层视图
@property (nonatomic, strong) UIView *alertView;// 弹出视图
@property (nonatomic, strong) UIView *topView;// 标题行顶部视图
@property (nonatomic, strong) UIButton *cancelButton;// 左边取消按钮
@property (nonatomic, strong) UIButton *sureButton;// 右边确定按钮
@property (nonatomic, strong) UILabel *titleLabel;// 中间标题
@property (nonatomic, strong) UIView *lineView;// 分割线视图

// 点击背景遮罩图层和取消、确定按钮的点击事件实现效果在基类中都是空白的，具体效果在子类中进行重写来控制
/** 点击背景遮罩图层事件 */
- (void)didTapBackgroundView:(UITapGestureRecognizer *)sender;
/** 取消按钮的点击事件 */
- (void)clickCancelButton;
/** 确定按钮的点击事件 */
- (void)clickSureButton;

@end

b、DatePickerSubview

// 日期选择完成之后的操作
typedef void(^DateResultBlock)(NSString *selectValue);

@interface DatePickerSubview : DatePickerSuperView

// 让使用者提供选择器的标题、最小日期、日期选择完成后的操作
+ (void)showDatePickerWithTitle:(NSString *)title minDateString:(NSString *)minDateString resultBlock:(DateResultBlock)resultBlock;

@end

4、创建数据源

选择器数据的加载，从设定的最小日期到当前月

- (NSMutableArray<NSString *> *)data
{
    if (!_data)
    {
        _data = [[NSMutableArray alloc] init];
        
        NSDate *currentDate = [NSDate date];
        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
        [formatter setDateFormat:@"yyyy-MM"];
        NSString *dateString = [formatter stringFromDate:currentDate];
        NSDate *newDate;
        
        // 通过日历可以直接获取前几个月的日期，所以这里直接用该类的方法进行循环获取数据
        NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
        NSDateComponents *lastMonthComps = [[NSDateComponents alloc] init];
        NSInteger lastIndex = 0;

        // 循环获取可选月份，从当前月份到最小月份，用字符串比较来判断是否大于设定的最小日期
        while (!([dateString compare:self.minDateString] == NSOrderedAscending))
        {
            [_data addObject:dateString];
            lastIndex--;
            
            // 获取之前n个月, setMonth的参数为正则向后，为负则表示之前
            [lastMonthComps setMonth:lastIndex];
            newDate = [calendar dateByAddingComponents:lastMonthComps toDate:currentDate options:0];
            dateString = [formatter stringFromDate:newDate];
        }
    }
    return _data;
}

5、配置选择器

a、UIPickerViewDataSource

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
    return 1;
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
    return self.data.count;
}

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    return self.data[row];
}

b、UIPickerViewDelegate

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    self.selectValue = self.data[row];
}

// 高度
- (CGFloat)pickerView:(UIPickerView *)pickerView rowHeightForComponent:(NSInteger)component
{
    return 35.0f;
}

// 宽度
- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component
{
    return 100;
}

c、选择器按钮的点击事件

// 取消(重写)
- (void)clickCancelButton
{
    [self dismissWithAnimation:YES];
}

// 确定（重写）
- (void)clickSureButton
{
    NSLog(@"点击确定按钮后，执行block回调");
    
    [self dismissWithAnimation:YES];
    if (_resultBlock)
    {
        _resultBlock(_selectValue);
    }
}

// 背景（重写）
- (void)didTapBackgroundView:(UITapGestureRecognizer *)sender
{
     // 蒙层背景点击事件看需求，有的需要和取消一样的效果，有的可能就无效果
     [self dismissWithAnimation:YES];
}

关闭选择器视图

- (void)dismissWithAnimation:(BOOL)animation
{
    [UIView animateWithDuration:0.2 animations:^{
        // 动画隐藏
        CGRect rect = self.alertView.frame;
        rect.origin.y += (DatePictureHeight + TopViewHeight);
        self.alertView.frame = rect;
        
        self.backgroundView.alpha = 0;
    } completion:^(BOOL finished) {
        // 父视图移除
        [self.cancelButton removeFromSuperview];
        [self.sureButton removeFromSuperview];
        [self.titleLabel removeFromSuperview];
        [self.lineView removeFromSuperview];
        [self.topView removeFromSuperview];
        
        [self.picker removeFromSuperview];
        [self.alertView removeFromSuperview];
        [self.backgroundView removeFromSuperview];
        [self removeFromSuperview];
        
        // 清空 dealloc，创建的视图要清除，避免内存泄露
        self.cancelButton = nil;
        self.sureButton = nil;
        self.titleLabel = nil;
        self.lineView = nil;
        self.topView = nil;
        
        self.picker = nil;
        self.alertView = nil;
        self.backgroundView = nil;
    }];
}

d、弹出选择器视图

+ (void)showDatePickerWithTitle:(NSString *)title minDateString:(NSString *)minDateString resultBlock:(DateResultBlock)resultBlock
{
    DatePickerSubview *datePicker = [[DatePickerSubview alloc] initWithTitle:title minDateString:minDateString resultBlock:resultBlock];
    [datePicker showWithAnimation:YES];
}

弹出选择器视图

- (void)showWithAnimation:(BOOL)animation
{
    // 获取当前应用的主窗口
    UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
    [keyWindow addSubview:self];
    
    if (animation)
    {
        // 动画前初始位置
        CGRect rect = self.alertView.frame;
        rect.origin.y = SCREEN_HEIGHT;
        self.alertView.frame = rect;
        
        // 浮现动画
        [UIView animateWithDuration:0.3 animations:^{
            CGRect rect = self.alertView.frame;
            rect.origin.y -= DatePictureHeight + TopViewHeight;
            self.alertView.frame = rect;
        }];
    }
}
