    // 兼容系统pop手势 / FDFullscreenPopGesture / 如有自定义手势，需自行在此处判断
    if ([otherGestureRecognizer.view isKindOfClass:NSClassFromString(@"UILayoutContainerView")]) {

    // ReSideMenu 及其他一些手势的开启，需要在这自行此有些。目前还没完全兼容好，会引起一个小问题
    if (self.otherGestureRecognizerSimultaneously) {
        // 再判断系统手势的state是began还是fail，同时判断scrollView的位置是不是正好在最左边
        if (otherGestureRecognizer.state == UIGestureRecognizerStateBegan && self.contentOffset.x == 0) {
            return YES;
        }
    }
    
    return NO;
