给UIView增加category
.h
/**pop视图单独使用*/
@property (nonatomic, copy) void(^popSuccessBlock)(void);
@property (nonatomic, copy) void(^popDismissBlock)(void);
.m
-(void)setPopSuccessBlock:(void (^)(void))popSuccessBlock{
objc_setAssociatedObject(self, @"popSuccessBlock", popSuccessBlock, OBJC_ASSOCIATION_COPY_NONATOMIC);
}-(void (^)(void))popSuccessBlock{
return objc_getAssociatedObject(self, @"popSuccessBlock");
}-(void)setPopDismissBlock:(void (^)(void))popDismissBlock{
objc_setAssociatedObject(self, @"popDismissBlock", popDismissBlock, OBJC_ASSOCIATION_COPY_NONATOMIC);
}-(void (^)(void))popDismissBlock{
return objc_getAssociatedObject(self, @"popDismissBlock");
}
【弹出视图的动画工具类】具体使用:
//具体在那个view层上弹出可自定义
OptionOrderSureView *view = [[OptionOrderSureView alloc] init];
[PopupTool pop:view TargetView:KeyWindow PopDirection:(PopDirectionCenter)];
//OptionOrderSureView占用整个window即可, 弹窗视图的close事件调用下
-(void)close{
BLOCK_EXEC(self.popDismissBlock);
}
