It worked

2.

viewDidLoad{
    .......
    [self setupExclude];
}

- (void)setupExclude{
    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPG)];
    longPress.minimumPressDuration = 0.2;
    [self.webview addGestureRecognizer:longPress];

    UITapGestureRecognizer *singleTapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:nil];
    singleTapGesture.numberOfTapsRequired = 1;
    singleTapGesture.numberOfTouchesRequired  = 1;
    [self.webview addGestureRecognizer:singleTapGesture];

    UITapGestureRecognizer *doubleTapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(longPG)];
    doubleTapGesture.numberOfTapsRequired = 2;
    doubleTapGesture.numberOfTouchesRequired = 1;
    [self.webview addGestureRecognizer:doubleTapGesture];
    [singleTapGesture requireGestureRecognizerToFail:doubleTapGesture];
}
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender{
    BOOL res = [super canPerformAction:action withSender:sender];
    UIMenuController.sharedMenuController.menuVisible = NO;
    self.webview.userInteractionEnabled = NO;
    self.webview.userInteractionEnabled = YES;
    return res;
}
- (void)longPG{
    UIMenuController.sharedMenuController.menuVisible = NO;
    self.webview.userInteractionEnabled = NO;
    self.webview.userInteractionEnabled = YES;
}

3. Done!
