新浪微博样式的ActionSheet
实现此功能的关键是在view里面生成一个UIWindow（该window会自动被加入到已有的window上面），然后设置windowlevel和hidden属性就可以显示或者隐藏。
//懒加载window，新建window之后会被自动添加到已有window上，只要设置windowLevel和hidden属性即可显示 -(UIWindow *)actionWindow{ if (!_actionWindow) { _actionWindow = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds]; _actionWindow.windowLevel = UIWindowLevelAlert; _actionWindow.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:.3]; } return _actionWindow; } //显示 -(void)show{ //设置self初始位置 self.frame = CGRectMake(0, ZDHEIGHT, ZDWIDTH, ZDHEIGHT); //添加本身到新建window [self.actionWindow addSubview:self]; self.actionWindow.hidden = NO; [UIView animateWithDuration:ZDANIMATIONTIME animations:^{ self.frame = CGRectMake(0, 0, ZDWIDTH, ZDHEIGHT); }]; } -(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ [self dismissFromeSuperView]; } //移除 -(void)dismissFromeSuperView { [UIView animateWithDuration:ZDANIMATIONTIME animations:^{ self.frame = CGRectMake(0, ZDHEIGHT, ZDWIDTH, ZDHEIGHT); } completion:^(BOOL finished) { [self removeFromSuperview]; self.actionWindow.hidden = YES; self.actionWindow = nil; }]; }
