我正在使用滑动手势在选项卡之间使用假的uitabbarcontroller在uIscrollview内的4个UiviewController子类中播放，并在UISCrollview内部进行4个UiviewController子类，并在每个中都有UipangeSturreerecognizer，并在每个中都有uipangeSturreerecognizer，以检测Swipes和Swips swips tabs。最终的效果是核心导航，就像您在Snapchat上看到的那样。但是，这些屏幕之一包含地图视图(Mapbox Map(，该视图具有其自己的手势识别器。
我希望用户能够通过从屏幕的右边缘检测滑动来在地图本身上滑动到另一个选项卡。我已经尝试在右侧的该区域中的一个看不见的Uiview中添加一个UipangeSturerecognizer，但这提供了一个繁琐的，毫无疑问的选项卡开关，并且从下面的地图中拦截了触摸事件。
。如何同时允许两个手势识别者同时接收事件，或仅根据滑动的开始位置及其距离和方向过滤一些事件？
