关于手势之间的冲突的解决方法

先说下，产生冲突的背景.我的主界面是个UINavigationController，我给导航控制器添加了个UIScreenEdgePanGestureRecognizer，设置滑动边界为左边界.代码如下:

  panGes = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(onSlideEdgeGes:)];

        [navigationController.view addGestureRecognizer:panGes];

        panGes.edges = UIRectEdgeLeft;

然后我在主界面添加了个UIScrollView，ScrollView自带滑动手势会屏蔽panGes的手势.

解决方法:通过设置手势重叠的时候的触发优先级()

CGRect headViewRect = CGRectMake(0, 0, CGRectGetWidth(APPRECT),CGRectGetHeight(self.view.frame) - FOOTERVIEW_HEIGHT);

    headScrollView = (CustomScrollView *)initScrollViewWithClass([CustomScrollView class],self.view, headViewRect, self, CGSizeMake(deviceArrs.count * CGRectGetWidth(headScrollView.frame), CGRectGetHeight(headScrollView.frame)), YES);

    headScrollView.pagingEnabled = YES;

    headScrollView.bounces = FALSE;

    headScrollView.showsVerticalScrollIndicator = FALSE;

关键代码:headScrollView的手势和panges重合时panges优先

    [headScrollView.panGestureRecognizer requireGestureRecognizerToFail:appDelegate.rootNavigtionManager.panGes];
