ios - 在 UIButton 单击时显示像 PopUpView 一样的 UIView？

Question

我有 UiView(PromoView),我想在 UIButton 的操作上打开 PromoView，同时在弹出 View 打开时设置背景模糊，当用户单击 View 中的任意位置时，PoPView 将被隐藏。这是我的代码..

-(IBAction)PromoCode_btn:(id)sender
{
    _PromoView.hidden=NO;
    _PromoView.transform = CGAffineTransformMakeScale(0.01, 0.01);
    [UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
    self.view.alpha=0.5;
    _PromoView.transform = CGAffineTransformIdentity;
    } completion:^(BOOL finished){
  }];
}

它只是用动画打开，帮我写代码...

Answer 1

在viewDidLoad中添加UITapGestureRecognizer到 View

UITapGestureRecognizer *singleFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];

[_PromoView addGestureRecognizer:singleFingerTap];

//The event handling method
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer{
  //Do animation here...

  _PromoView.hidden = YES;

}
