Answer 1

Use UITapGestureRecognizer gesture to detect touches on any view inherited from UIView.

Use as below…..

Add Tap gesture UITapGestureRecognizer to myImageView view (type of UIImageView).

UITapGestureRecognizer *myTapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(gestureTapEvent:)];
myImageView.userInteractionEnabled = YES;
[myImageView addGestureRecognizer:myTapGesture];
[myTapGesture release];    

Implement gestureTapEvent: method to receive the touch event.

-(void)gestureTapEvent:(UITapGestureRecognizer *)gesture 
{

}

UPDATED:

you could access view with you attached the gesture using view property of UIGestureRecognizer .

@property(nonatomic, readonly) UIView *view;

So your gestureTapEvent: method should be like as below .

-(void)gestureTapEvent:(UITapGestureRecognizer *)gesture 
{
     UIImageView* myImageView = (UIImageView*)gesture.view ;
}
