UITextView输入框不让出放大镜，粘贴功能

写UITextView的继承类，在.m中重写下面方法

-(void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer

{

    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) {

        gestureRecognizer.enabled = NO;

    }

    [super addGestureRecognizer:gestureRecognizer];

}

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

{

    return NO;

}
