How to disable magnification in UITextView

Question

I want to get rid of magnification and text selection in UITextView but I need phone number, link and address detectors. I am using

-(void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer {
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) {
        gestureRecognizer.enabled = NO;
    }
    [super addGestureRecognizer:gestureRecognizer];
    return;}

to stop magnification, but it also stops selection phone number / address / link detected by textview. If I do [_txtView setSelectable:NO]; it stops both magnification and text selection as well as data detection.

Answer 1

After quite a long time trying, I managed to stop text selection, magnifying, and keeping data detection (links clickable etc) by overriding addGestureRecognizer on a UITextView subclass allowing only UILongPressGestureRecognizer delaying touch ending:

UIUnselectableTextView.m

-(void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
{
    if([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]] && gestureRecognizer.delaysTouchesEnded)
    {
        [super addGestureRecognizer:gestureRecognizer];
    }
}

Put image on your UITextview in .xib file then put below code.

 - (void)viewDidLoad
  {
      [super viewDidLoad];
      self.navigationController.navigationBarHidden = YES;

      UITapGestureRecognizer *tappress= [[UITapGestureRecognizer alloc] initWithTarget:self    action:@selector(longPressed:)];
      img.userInteractionEnabled = YES;
      [img addGestureRecognizer:tappress];
}

-(void)longPressed:(UILongPressGestureRecognizer *)sender
{
    [yourtextview becomeFirstResponder];
}

in my code img is a UIImageview

Try this:

1. Set the delegate of the textview to your viewcontroller

2. add this method

   - (void)textViewDidChangeSelection:(UITextView *)textView
   {
        NSRange selected;
        selected.location = 0;
        selected.length = 0;
        textView.selectedRange = selected;
   }
   

This would disable the magnification but still have links clickable

You just need to make sure you have set right parameters for the UItextfield (and there is no need to actually have it done by overriding the gestures). I guess if you change your attributes for "Behaviour" and "Detection" in interface builder as following you will have your desired behaviour.
