Disabling Magnifying Glass in UITextView in an iPhone App

Question

I want to display text and I want to be able to know where in this text a user touches. Because the text could be long, I wanted to use a UITextView so that wrapping and everything would be taken care of. I want my own event handling for when a touch begins or moves. My problem is that the magnifying glass and select/select all menu are interrupting my touchesMoved events.

How can i disable the magnifying glass, but still have user interaction enabled so that I can detect the touches?

You have to create a subclass and override these two functions to disable select/select all/copy/ and magnifying

select/select all/copy/:

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender

magnifying:

- UILongPressGestureRecognizer
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer

I'd suggest to check the gestureRecognizers property.

You will find a lot of them in the array and might want to either remove them all or to find the ones that triggers the event you want to intercept and remove/replace it.

I used it to remove copy/paste and magnifying glass functionalities from an UITextField

Dwery, how did you do it? I removed 8 gesture recognizers but the magnifying glass is still there when I hold. – Natan R. Sep 06 '12 at 15:12
Natan, IIRC gesture recognizers are re-initialized after each event. So i remove the stock recognizers and add my own after each event – dwery Sep 12 '12 at 14:31
Thanks, Dwery! I'll check that – Natan R. Sep 12 '12 at 14:32
