在.m文件中添加此代码，您已在其中调用子类UITextfield

   -(void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer 
  {
    //Prevent zooming but not panning
     if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) 
        {
              gestureRecognizer.enabled =YES;
        }
       [super addGestureRecognizer:gestureRecognizer];
        return;
   }
