Question

-(void)tapDetected:(UIGestureRecognizer*)recognizer{
(UIImageView)(recognizer.view).tag)
    ;} 

I want to convert type of recognizer’s view to imageview so that i can use tag of image as a reference. how can i do that?

Answer 1

The tag property is declared in UIView, not UIImageView. No cast is needed.

NSInteger myTag = recognizer.view.tag;

For illustration purposes, this is how you would cast the view to UIImageView if you wanted, for example, access to its image property:

UIImage *img = ((UIImageView *)recognizer.view).image;

For ease of use, you can use a local variable to make subsequent accesses cleaner:

UIImageView *imageView = (UIImageView *)recognizer.view;
UIImage *img = imageView.image;
