先上效果图
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!
