取消隐藏视图时出现iOS Autolayout致命错误NSInternalInconsistencyException
我正在使用具有3个视图的堆栈视图，一个是具有集群图标的GMS mapview，另外两个视图是具有多个嵌套堆栈视图的视图。当我在mapview上选择一个图标时，它将在动画块中取消隐藏其他两个视图中的一个或两个。
有时而且并非总是当我点击以在地图视图上选择群集图标时，它会导致以下崩溃错误。请参阅界面构建器中视图的附加图像。每个标签都使用高度约束，优先级为@ 999，以满足堆栈视图的歧义。

答案 0 :(得分：0)
我发现蓝绿色的高度为'＃34; Station Name＆＃34;查看高度约束优先级为1000.将此更改为999解决了问题。
垂直堆栈视图的所有其他高度限制都具有999的优先级，因此堆栈视图可以在动画期间折叠视图。
