Xamarin RelativeLayout中的布局不'；不响应iOS中的输入

在iOS中，点击内部布局（在本例中为向上长点击）时不会触发点击事件。在Android上工作得非常好。我尝试过更新Xamarin.表单，使用普通手势识别器，使用Mr.手势，都得到了相同的结果。我做错了什么？有谁能帮帮我吗？我已经试了好几个星期了。谢谢你抽出时间

由于相对布局具有Z-顺序，因此您很有可能用长按注册来掩盖视图。在android中（如果我没记错的话），你可以有一堆手势识别器，每一个都返回它是否处理了触摸事件。事件最终将沿着视图堆栈向上运行，直到其被处理或未被处理；这使得它在iOS无法。。如果您提供一个屏幕截图并突出显示问题所在，这可能会有所帮助。我也尝试过仅使用一个内部只有一个StackLayout的RelativeLayout。我得到了同样的结果。
