滑动控件UISlider

UISlider跟UISwitch有点儿类似，都是继承自UIControl
既然UISlider是表示一个CGRange，那么就有一个最大值（maximumValue）和一个最小值（minimumValue），既然UISlider又是一个选择器，那么就有一个当前的选择值（value），这三个值都是UISlider的属性。
同样的，UISlider选择器被改变时，会触发UIControlEventValueChanged的事件，所以我们可以通过添加addTarget:::方法为事件添加处理方法。

#import "ViewController.h"

@interface ViewController ()

@property(nonatomic,strong)UISlider *slider;

[提示窗UIAlertView与UIAlertController的用法（持续更新中)]

一般在if判断中加入
1.第一种基础型

image.png

全都在xxx.m功能文件中编写

UIAlertView（基础版）：

1 UIAlertView *WXinstall=[[UIAlertView alloc]initWithTitle:@"提示框" message:@"提示信息" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];//一般在if判断中加入
2 [WXinstall show];

//监听点击事件 代理方法
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *btnTitle = [alertView buttonTitleAtIndex:buttonIndex];
    if ([btnTitle isEqualToString:@"取消"]) {
         NSLog(@"你点击了取消");
    }else if ([btnTitle isEqualToString:@"确定"] ) {
         NSLog(@"你点击了确定");
        NSString *str = [NSString stringWithFormat:
                         @"https://itunes.apple.com/cn/app/wei-xin/id414478124?mt=8"];11         [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
    }//https在iTunes中找，这里的事件是前往手机端App store下载微信
}

UIAlertController（基础版）：

UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"提示" message:@"提示信息" preferredStyle:UIAlertControllerStyleAlert];//UIAlertControllerStyleAlert视图在中央
 UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];  
 UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {  
 NSString *str = [NSString stringWithFormat: 
 @"https://itunes.apple.com/cn/app/wei-xin/id414478124?mt=8"];  
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];  
  }];//https在iTunes中找，这里的事件是前往手机端App store下载微信 
  [alertController addAction:cancelAction];  
  [alertController addAction:okAction]; 
 [self presentViewController:alertController animated:YES completion:nil];

2.第二种没得选型。

image.png

UIAlertView（基础版）：

1 UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"提示" message:@"你确定要退出应用吗？" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
2 [alert show];

3.第三种多选型。

image.png

//UIAlertControllerStyleAlert在中央屏幕。

//UIAlertControllerStyleActionSheet在屏幕底部。

UIAlertView（基础版）：iOS8都弃用这里就略。

UIAlertController（基础版）：

UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"title" message:@"message" preferredStyle:UIAlertControllerStyleActionSheet];
 //UIAlertControllerStyleAlert在中央屏幕。
 //UIAlertControllerStyleActionSheet在屏幕底部。
        UIAlertAction *useCamera = [UIAlertAction actionWithTitle:@"使用相机拍照" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSLog(@"这里是要调用相机拍照功能");
        }];
        UIAlertAction *desAction = [UIAlertAction actionWithTitle:@"destructive" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSLog(@"这里是要调用销毁功能");
        }];
        UIAlertAction *usePhoto = [UIAlertAction actionWithTitle:@"使用相册照片" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSLog(@"这里是要调用相册功能");
        }];
        UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
        [alertController addAction:useCamera];
        [alertController addAction:desAction];
        [alertController addAction:usePhoto];
        [alertController addAction:cancelAction];
        [self presentViewController:alertController animated:YES completion:nil];

如果手机没有安装微信客户端的情况下，不要提示用户去安装，因为可能遇到审核的人不小心把你的应用拒了。

UIAlertView和UIActionSheet在iOS8已经过期了，你仍然可以继续使用。UIAlertController这个接口类是一个定义上的提升，它添加简单，展示Alert和ActionSheet使用统一的API。因为UIAlertController使UIViewController的子类，他的API使用起来也会比较熟悉！

image.png

UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"选择睡前时间（分钟）" message:nil preferredStyle:UIAlertControllerStyleAlert];
        NSArray *timeArr = @[@"5",@"10",@"15",@"20",@"30",@"60"];
        NSInteger timeCount = [timeArr count];
        for (int i=0; i<timeCount; i++) {
            [alertVC addAction:[UIAlertAction actionWithTitle:timeArr[i] style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
                [sender setTitle:action.title forState:UIControlStateNormal];
            }]];
        }
        [self presentViewController:alertVC animated:YES completion:nil];

UIActivityIndicatorView 非常简单 ，就是一个转圈圈的控件

一、UIActivityIndicatorView的常用方法及属性

//初始化方法
- initWithActivityIndicatorStyle

//控制方法
- startAnimating   //开始转圈
- stopAnimating   //停止转圈
- isAnimating        //转圈的状态

//常用属性
hidesWhenStopped              //停止转圈后隐藏
activityIndicatorViewStyle     //样式
color                                   //颜色  （iOS 5  引入）
 
//样式
typedef enum { 
UIActivityIndicatorViewStyleWhiteLarge,   //白色圆圈 但是要大些
UIActivityIndicatorViewStyleWhite,           //白色圆圈
UIActivityIndicatorViewStyleGray,            //灰色圆圈
} UIActivityIndicatorViewStyle;

二、UIActivityIndicatorView的使用

UIActivityIndicatorView *testActivityIndicator = [UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite]];
testActivityIndicator.center = CGPointMake(100.0f, 100.0f);//只能设置中心，不能设置大小
[testActivityIndicator setFrame = CGRectMack(100, 100, 100, 100)];//不建议这样设置，因为UIActivityIndicatorView是不能改变大小只能改变位置，这样设置得到的结果是控件的中心在（100，100）上，而不是和其他控件的frame一样左上角在（100， 100）长为100，宽为100.
[self addSubview:testActivityIndicator];
testActivityIndicator.color = [UIColor redColor]; // 改变圈圈的颜色为红色； iOS5引入
[testActivityIndicator startAnimating]; // 开始旋转
[testActivityIndicator stopAnimating]; // 结束旋转
[testActivityIndicator setHidesWhenStopped:YES]; //当旋转结束时隐藏

UISegmentedControl 分段控件

一、简介
<<分段控件提供一栏按钮（有时称为按钮栏），但只能激活其中一个按钮。分段控件会导致用户在屏幕上看到的内容发生变化。它们常用于在不同类别的信息之间选择，或在不同的应用屏幕之间切换
<<继承关系：UISegmentedControl-->UIControl-->UIView-->UIResponder-->NSObject
格式为

UISegmentedControlSegmentAlone = 4,  // 在只有一个标签的时候生效
};


[segC setContentPositionAdjustment:UIOffsetMake(0, -60) forSegmentType: UISegmentedControlSegmentAlone
barMetrics: UIBarMetricsDefault];

-(void)setContentPositionAdjustment:(UIOffset)adjustment forSegmentType:(UISegmentedControlSegment)leftCenterRightOrAlone barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

29-->获取自定义偏移量

UIOffset offset= [segC s contentPositionAdjustmentForSegmentType: : UISegmentedControlSegmentAlone
barMetrics: UIBarMetricsDefault];

-(UIOffset)contentPositionAdjustmentForSegmentType:(UISegmentedControlSegment)leftCenterRightOrAlone barMetrics:(UIBarMetrics)barMetrics NS_AVAILABLE_IOS(5_0) UI_APPEARANCE_SELECTOR;

UISegmentedControl自定义

需求样式如下：

·每个segment都能被点击，相当于集成了多个button
·需求是 点击不同button切换不能的View 切换不同的页面。

由于我们产品设计中，对于这样的切换设计很多，每个模块都会设计到。所以就想到了，封装一个segmentView,使用方便。
使用者，只需要创建segmentView（传入几个item，就是几个button）然后会暴露segmentSwitchBlock的事件，用于处理不同页面之间的切换问题。下面就是代码。

代码块：
.h

#import <UIKit/UIKit.h>
#import "SCViewProtocol.h"

@interface SCSegmentView : UIView<SCViewProtocol>

@property (nonatomic,copy) void  (^segmentSwitchBlock) (long selectedSegmentIndex);

@property (nonatomic,assign) long selectedSegmentIndex;

- (instancetype)initWithItemList:(NSArray *)itemList;

@end

首先先针对这个SCViewProtocol协议说明一下：
SCViewProtocol这个协议定义了几个方法：
作用：省去了每次都要拼写的时间，让每一个参与该项目的开发者都遵循这个原则，对于排错有很好的帮助。清晰明了。
~传入的数组的目的：标题显示几个button会由数组的个数来决定，所以需要开发者传入一个数组，来显示标题内容。

#import <Foundation/Foundation.h>

@protocol SCViewProtocol <NSObject>
@optional;
//设置数据源
- (void)setViewWithModel:(id)obj;
//添加子视图
- (void)addSubViews;
//设置约束
- (void)setConstraints;

//初始化ui默认
- (void)configUIDefault;

- (void)reloadUI;

@end

.m

@interface SCSegmentView ()
@property (nonatomic, strong) UISegmentedControl *segment;
@property (nonatomic, strong) NSArray *itemList;

@end

@implementation SCSegmentView

-(instancetype)initWithItemList:(NSArray *)itemList{
    if (self = [super init]) {
        self.itemList = itemList;
        self.backgroundColor = [UIColor SCLightBlueColor];
        [self addSubViews];
        [self setConstraints];
    }
    return self;
}

-(void)addSubViews{
    [self addSubview:self.segment];
}

-(void)setConstraints{
    [self.segment mas_makeConstraints:^(MASConstraintMaker *make) {
        make.height.mas_equalTo(30);
        make.top.mas_equalTo(self.mas_top).mas_offset(10);
        make.width.mas_equalTo(self.mas_width).mas_offset(-50);
        make.centerX.mas_equalTo(self.mas_centerX);
    }];
}

创建UISegmentedControl

- (UISegmentedControl *)segment{
    if (!_segment) {
        _segment = [[UISegmentedControl alloc]initWithItems:self.itemList];
        _segment.tintColor = [UIColor SCWhiteColor];
        _segment.selectedSegmentIndex = 0;//选中第几个segment 一般用于初始化时选中
        [_segment addTarget:self action:@selector(segmentValueChanged:) forControlEvents:UIControlEventValueChanged];
        UIFont *font = [UIFont boldSystemFontOfSize:14.0f];
        NSDictionary *attributes = [NSDictionary dictionaryWithObject:font forKey:NSFontAttributeName];
        [_segment setTitleTextAttributes:attributes forState:UIControlStateNormal];

        _segment.selectedSegmentIndex = 0;
        _segment.layer.masksToBounds = YES;
        _segment.layer.cornerRadius = 3;
        [_segment addTarget:self action:@selector(segmentValueChanged:) forControlEvents:UIControlEventValueChanged];
    }
    return _segment;
}

设置segment的字体：

//设置Segment的字体
    NSDictionary *dic = @{
                          //1.设置字体样式:例如黑体,和字体大小
                          NSFontAttributeName:[UIFont fontWithName:@"Arial-BoldMT" size:20],
                          //2.字体颜色
                          NSForegroundColorAttributeName:[UIColor grayColor]
                          };

    [segment setTitleTextAttributes:dic forState:UIControlStateNormal];

其他行为、外观、添加、删除等相关内容：

//设置segment的外观和字体颜色
    segment.tintColor = [UIColor redColor];
    //segment.segmentedControlStyle = UISegmentedControlStyleBar;此属性在ios7之后不再有任何效果

    [segment setEnabled:NO]; //设置segment是否可用 此方法是其父类UIControl的方法
    [segment setEnabled:NO forSegmentAtIndex:2];//设置下标为2的segment不可用
    [segment setWidth:100 forSegmentAtIndex:2]; //这时下表为2的segment的宽度
    [segment setContentOffset:CGSizeMake(10, 10) forSegmentAtIndex:2];//设置内容偏移
    segment.apportionsSegmentWidthsByContent = YES; //是否根据segment的内容改变segment的宽度

    [segment insertSegmentWithImage:[UIImage imageNamed:@"3"] atIndex:2 animated:YES]; //添加分页,并设置图片
    [segment insertSegmentWithTitle:@"ddd" atIndex:0 animated:YES];//添加分页,并设置标题
    [segment numberOfSegments];//得到segment的数量
    [segment removeAllSegments];//移出所有segment
    [segment removeSegmentAtIndex:2 animated:YES];//移出下标为2的segment
    segment.selectedSegmentIndex = 0;//选中第几个segment 一般用于初始化时选中

如果需要给这个segment增加图片，可以用下面的方法：

//设置下标为4的segment的图片
    [segment setImage:[UIImage imageNamed:@"kaixin"] forSegmentAtIndex:4];

切换事件

- (void)segmentValueChanged:(UISegmentedControl *)segment{
    self.segmentSwitchBlock?self.segmentSwitchBlock(segment.selectedSegmentIndex):nil;
}

存储当前点击segment的状态值

-(long)selectedSegmentIndex{
    return self.segment.selectedSegmentIndex;
}

具体使用：

-(SCSegmentView *)segmentView{
    if (!_segmentView) {
        _segmentView = [[SCSegmentView alloc]initWithItemList:@[@"我的待办",@"我的办结"]];
        @Weakify(self);
        _segmentView.segmentSwitchBlock = ^(long segmentIndex) {
        @Strongify(self);
        [self segmentValueChanged:segmentIndex];
        };
    }
    return _segmentView;
}

-(void)segmentValueChanged:(long)selectedSegmentIndex{
}

通过获取segmentView中index的值 来刷新数据

 if (self.segmentView.selectedSegmentIndex==0){
}

以上就是针对UISegmentedControl的View简单的封装。

    [super viewDidLoad];

    [action release];
