How to Disable Copy, Paste and Select for UITextView

Need to use UITextView, but don't want Copy, Paste and Select feature. How to disable that? Tried overwriting canPerformAction:withSender but I got still a flash of quickly disappearing popup menu and selection.

Subclass UITextView and overwrite canBeforeFirstResponder to return always NO:

@interface MyUITextView : UITextView
@end
@implementation MyUITextView
- (BOOL)canBecomeFirstResponder
{
   return NO;
}
@end

Now you have completely hidden and disabled copy, paste and select for UITextView!
