Removing image from UIImageView

Question

I load a UIImageView with an image depending on user interaction. When the parent view is initially displayed, no image has been selected and the imageview is blac

Answer 1

You can use a UITapGestureRecognizer to remove the image for a given number of clicks.

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onImageTapped:)];

tapGesture.delegate = self;

tapGesture.numberOfTapsRequired = 2; // no. of taps (clicks) on which you want to remove the image

[myImageView addGestureRecognizer:tapGesture];

and give the method's definition:

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

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