Help in detecting a touch in UIImageViews

I'm trying to detect a touch in a UIImageView. I'm trying to make it such that if a user taps on an image, it wil call a method, and if a user taps on another, it will call another method. Here is my code so far:

Code:

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch* touch = [touches anyObject];
    
    if ([touch view] == self.imageView1){
        [self doAMethod];
        NSLog(@"Touched!");
    }
    else if ([touch view] == self.imageView2){ 
        [self doAnotherMethod];
    }
    else if ([touch view] == self.imageView3){
        [self doYetAnotherMethod];
    }
    else if([touch view] == self.imageView4){
        [self doADifferentMethod];
    }
}

Just to let you know, I ticked the userInteractionEnabled box for the images in the IB.

So far, it doesn't work. Please help. Even the

Code:

NSLog

statement does not do anything, signifying that it didn't respond to the touch at all.
