Tap detection not working on UIImageView

Question

In my .m file I added:

@property (strong, nonatomic) UIImageView *star1;

Then in a method I did:

UIImage *star1Image;
star1         


        

Answer 1

So, since components like UILabel or UIImageView aren't design to be "touchable", to add a "touchable" feature (like a UITapRecognizer), you have to set their userInteractionEnabled to YES.

So, even if you set this property correctly for your UIImageView (star1), since you add it as a subview of ratingLabelBody, you couldn't trigger your UITapGestureRecognizer (imgTouchUp:).
You have to do the same to the parent view of your star1, which is ratingLabelBody.

Translated with code, you just had to do:

[ratingLabelBody setUserInteractionEnabled:YES];
