Question

I have an ImageView and I want that when user press the image view to display a message as an alert. What method should I use? Can you provide me an example ?

Thanks in advance..

Add a UITapGestureRecognizer:

imageView.userInteractionEnabled = YES;
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] 
    initWithTarget:self action:@selector(handleTap:)];
[imageView addGestureRecognizer:tapRecognizer];
[tapRecognizer release];

And then your callback…

- (void)handleTap:(UITapGestureRecognizer *)tapGestureRecognizer
{
  //show your alert...
}
