iphone - UIImageView触摸事件

Question

我想在触摸名为 as(image1).Imageview 放置在 uiview(view1) 中的 uiimageview 时调用按钮单击事件。

这是我的代码:

- (IBAction)buttonClicked:(id)sender
{

 myTimer = [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(alphabutt:) userInfo:nil repeats:NO];
 }


-(IBAction)alphabutt:(id)sender
{
 NSLog(@"alphabutt!");


 if(i==1)
 {
  NSLog(@"i==1");
  [image1 setImage:[UIImage imageNamed:@"appleimg.jpg"]];
  [view1 addSubview:image1];  
  transition1 = [CATransition animation];

  transition1.duration = 0.75;

  transition1.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

  transition1.type=kCATransitionReveal;
  transition1.subtype=kCATransitionFromRight;
  transitioning = YES;
  transition1.delegate = self;
  [image1.layer addAnimation:transition1 forKey:nil];  
 }
 if(i==2)
 {
  NSLog(@"i==2");
  [image1 setImage:[UIImage imageNamed:@"boatimg.jpg"]];
  [view1 addSubview:image1];  
  transition2 = [CATransition animation];

  transition2.duration = 0.75;

  transition2.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

  transition2.type=kCATransitionFade;
  transition2.subtype=kCATransitionFromRight;
  transitioning = YES;
  transition2.delegate = self;
  [image1.layer addAnimation:transition2 forKey:nil];

  i=0;
 }
i++;

}

上面是我的代码，当单击按钮时，将调用buttonclicked事件。在buttonclick事件内，计时器正在以2.0的时间间隔调用alphabutt(按钮单击事件)。每隔2.0调用一次alphabutt。我想要当我触摸 uiimageview(image1) 时执行此动画，然后只有它调用按钮单击事件(alphabutt)。我怎样才能为imageview编写触摸事件...

请简要解释一些执行 uiimageview 触摸事件的代码...

您可以使用通过addGestureRecognizer添加到UIImageView的UITapGestureRecognizer

片段:

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(bannerTapped:)];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired = 1;
[iv addGestureRecognizer:singleTap];
[iv setUserInteractionEnabled:YES];

和

- (void)bannerTapped:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"%@", [gestureRecognizer view]);
}
