UIImageView Touch Event

Question

Hi,

I want to call my button click event while touching the uiimageview named as(image1).Imageview placed in uiview(view1).

This is my code:

- (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++;

}

The above is my code while clicking the button the buttonclicked event is called.Inside buttonclick event the timer is working to call the alphabutt(Button click event)with the time intervel of 2.0.alphabutt is called with every 2.0.I want to do this animation when i'm touch the uiimageview(image1) then only it calls the button click event (alphabutt). how can i write the touch event for imageview...Plz help me out to do this...

Plz Explain briefly with some code to perform uiimageview touch event...

Thank u....(I'm waiting for ur reply) Renya

Make your image view user interaction enabled in the xib (or through the code if you are adding it programmatically) and use the UIResponder methods touchesBegan, touchesMoved, touchesEnded etc to detect the touch on the image view:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [touches anyObject];

    if ([touch view] == yourImageView)
    {
            //add your code for image touch here 
    }

}
