    前些时间在项目开发中用到这个带箭头的弹出框功能,为了开发进度,就随便在gitHub上找了个轮子使用了,也能实现我想要的功能,但是就是感觉不是想要的那种封装方式,使用起来比较麻烦,能不能像使用系统框架UIMenuController那样方便的使用这一控件呢?抱着这个想法,闲暇时间开始了HHPopController的探索

    首先这个自定义控件使用起来非常简单方便,且可定制性很高,你只需要像下面这样使用

        HHPopItem *item1 = [HHPopItem itemWithImage:[UIImage imageNamed:@"ic_addvoucher_qrcode"] title:@"创建群聊"];
        HHPopItem *item2 = [HHPopItem itemWithImage:[UIImage imageNamed:@"ic_addvoucher_cinema"] title:@"加好友/群"];
        HHPopItem *item3 = [HHPopItem itemWithImage:[UIImage imageNamed:@"ic_addvoucher_input"] title:@"面对面快传"];
        [HHPopController applyPopStyle:^(HHPopStyle *style) {
            style.borderColor = [UIColor cyanColor];
            style.borderWidth = 1.0f;
            style.itemTextColor = [UIColor whiteColor];
            style.dimColor = [UIColor colorWithWhite:0.1 alpha:0.3];
            style.itemBgColor = [UIColor colorWithWhite:0.3 alpha:1.0];
            
    //        HHPopSupplementaryStyle *header = [HHPopSupplementaryStyle defaultStyle];
    //        header.bgColor = style.itemBgColor;
    //        header.title = @"header";
    //        header.titleColor = [UIColor whiteColor];
    //        style.header = header;
    //        
    //        HHPopSupplementaryStyle *footer = [HHPopSupplementaryStyle defaultStyle];
    //        footer.bgColor = style.itemBgColor;
    //        footer.title = @"footer";
    //        footer.titleColor = [UIColor whiteColor];
    //        style.footer = footer;
        }];
        [HHPopController popSourceView:btn popItems:@[item1, item2, item3] selectionHandler:^(NSInteger idx, HHPopItem *item) {
            NSLog(@"%@", item.title);
        }];
    

    先来看下类HHPopItem的定义

    /// 弹出视图数据模型
    @interface HHPopItem : NSObject
    + (instancetype)itemWithTitle:(NSString *)title;
    + (instancetype)itemWithImage:(UIImage *)image title:(NSString *)title;
    @property (nonatomic, strong)UIImage *image;
    @property (nonatomic, strong)NSString *title;
    - (void)setHandler:(void (^)(NSInteger idx, HHPopItem *item))handler;
    @end
    

    这里你可以创建只含有标题或者含有图片和标题两种样式,并且可以通过block配置点击的回调

    方法+ (void)applyPopStyle:(void (^)(HHPopStyle *style))maker;通过block传进一个模型来配置该控件所有的样式,可定制的属性如下

    /// 弹出视图样式模型
    @interface HHPopStyle : NSObject
    
    /// 弹出视图的宽度
    @property (nonatomic, assign)CGFloat popWidth;
    
    /// 边框颜色
    @property (nonatomic, strong)UIColor *borderColor;
    /// 边框宽度
    @property (nonatomic, assign)CGFloat borderWidth;
    
    
    /// 行高
    @property (nonatomic, assign)CGFloat rowHeight;
    /// 圆角尺寸
    @property (nonatomic, assign)CGFloat cornerRadius;
    /// 蒙版颜色
    @property (nonatomic, strong)UIColor *dimColor;
    /// 箭头方向
    @property (nonatomic, assign)HHArrowStyle arrowStyle;
    /// 箭头离矩形边框的距离大小
    @property (nonatomic, assign)CGFloat arrowDistanceFromTargetRectBorder;
    /// 箭头尺寸, 对应三角形的宽高 default {15, 8}
    @property (nonatomic, assign)CGSize arrowSize;
    /// 弹框显现的区域限制
    @property (nonatomic, assign)UIEdgeInsets popAreaEdgeLimits;
    /// 出现的动画时间 default 0.25
    @property (nonatomic, assign)CGFloat animationIn;
    /// 小时的动画时间 default 0.25
    @property (nonatomic, assign)CGFloat animationOut;
    /// 是否能滚动 当弹框范围能够容纳的下为NO, 否则为YES
    @property (nonatomic, assign)BOOL bounces;
    
    /// 分割线颜色
    @property (nonatomic, strong)UIColor *separatorColor;
    /// 分割线内边距
    @property (nonatomic, assign)UIEdgeInsets separatorInset;
    
    /// 选项的背景颜色
    @property (nonatomic, strong)UIColor *itemBgColor;
    /// 选项的图片内容模式
    @property (nonatomic, assign)UIViewContentMode itemImageContentMode;
    /// 选项文字对齐方式
    @property (nonatomic, assign)NSTextAlignment itemTextAligment;
    /// 选项文字字体
    @property (nonatomic, strong)UIFont *itemTextFont;
    /// 选项文字颜色
    @property (nonatomic, strong)UIColor *itemTextColor;
    
    /// 头部样式
    @property (nonatomic, strong)HHPopSupplementaryStyle *header;
    
    /// 尾部样式
    @property (nonatomic, strong)HHPopSupplementaryStyle *footer;
    
    + (instancetype)defaultStyle;
    
    @end
    

    看注释应该很明显了,其中这里还可以通过HHPopSupplementaryStyle模型来配置头部数据和尾部数据,其实就是UITableView的header和footer,HHPopSupplementaryStyle的定义如下

    /// 弹出视图的追加视图模型 (header and footer)
    @interface HHPopSupplementaryStyle : NSObject
    
    /// 标题
    @property (nonatomic, copy)NSString *title;
    /// 标题高度
    @property (nonatomic, assign)CGFloat height;
    /// 标题文字对齐方式
    @property (nonatomic, assign)NSTextAlignment titleAligment;
    /// 标题文字颜色
    @property (nonatomic, strong)UIColor *titleColor;
    /// 标题背景颜色
    @property (nonatomic, assign)UIColor *bgColor;
    /// 标题文字字体
    @property (nonatomic, strong)UIFont *titleFont;
    /// 自定义头部视图
    @property (nonatomic, strong)UIView *customView;
    
    + (instancetype)defaultStyle;
    
    @end
    

    HHArrowStyle是个枚举类型

    /// 箭头方式
    typedef NS_ENUM(NSInteger, HHArrowStyle) {
        HHArrowStyleVerticalDefault = 0, ///< up or down based on source view location in window
        HHArrowStyleHorizontalDefault, ///< left or right based on source view location in window
        HHArrowStyleUp,///< up force
        HHArrowStyleDown,/// < down force
        HHArrowStyleLeft,///< left force
        HHArrowStyleRight///< right force
    };
    

    如果不需要显示箭头可以设置arrowSize为CGSizeZero。
    最后我们在看下HHPopController的定义

    /// 弹出视图控制器
    @interface HHPopController : NSObject
    
    + (void)applyReturnPopStyle:(HHPopStyle *(^)(HHPopStyle *style))maker;
    
    + (void)applyPopStyle:(void (^)(HHPopStyle *style))maker;
    
    + (void)popSourceView:(UIView *)view popItems:(NSArray<HHPopItem *> *)items selectionHandler:(void (^)(NSInteger idx, HHPopItem *item))handler;
    
    + (void)popTargetRect:(CGRect)rect soureceView:(UIView *)view popItems:(NSArray<HHPopItem *> *)items selectionHandler:(void (^)(NSInteger idx, HHPopItem *item))handler;
    
    + (BOOL)isPopVisible;
    
    + (void)dismiss;
    
    @end
    

    配置回调有两种方式,可以通过模型,也可以通过handler参数,使用起来是不是简单明了?既然封装就要封装的彻底点,外界怎么用着舒服就怎么来,嘿嘿,通过模型来配置一些属性,避开了要写一堆的代理方法或者block,但还是有一些缺点的,比如动画支持不是很丰富等

    另外还可以通过以下通知名监听对应的通知

    FOUNDATION_EXTERN NSString *const HHPopControllerWillPopNotification;
    FOUNDATION_EXTERN NSString *const HHPopControllerDidPopNotification;
    FOUNDATION_EXTERN NSString *const HHPopControllerWillHidenNotification;
    FOUNDATION_EXTERN NSString *const HHPopControllerDidHidenNotification;
    

    可以通过cocopods安装使用

    pod 'HHPopController'
    

    好了,功能就这么多,有兴趣的可以看下源码,也很好理解,有什么问题或建议欢迎留言,如果能在开发中帮助到你也算没有白忙活,谢谢大家,喜欢的麻烦给个赞呗!
