iPhone SDK - Using touches to delete images

Question

how can you delete an image by using touches in the iphone sdk? Im making a game with images so i was wondering if there is a way were if you touch an image it gets deleted from the view.

Answer 1

Yes. You can add UITapGestureRecognizer to your image view, and in the recognizer action you can get the image view by using recognizer.view propery. And you can delete/remove it from its super view by using [image removeFromSuperview] method.

UITapGestureRecognizer *tgr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onImageTapped:)];
[imageView addGestureRecognizer:tgr];
[tgr release];

And the onImageTapped: method looks like this,

- (void)onImageTapped:(UITapGestureRecognizer*)recognizer {

    UIImageView *imgView = (UIImageView*) recognizer.view;
    [imgView removeFromSuperview];
}
