我正在快速处理Imessage应用程序。每当我向下滑动以从展开视图转到紧凑视图时，都会收到以下错误。 注意：它会进入紧凑视图，但在过渡时会冻结几秒钟，然后显示紧凑视图
Bounding path likely out of sync with its coordinate space: The view's bounds must contain the bounding rect. Bounding rect: {{0, 0}, {414, 646}}; coordinate space: <_UIHostedWindow: 0x101200120; frame = (0 0; 414 267); gestureRecognizers = <NSArray: 0x281357cc0>; layer
= <UIWindowLayer: 0x281d50d40>>
到目前为止，这是我的代码的副本，我有2个View Controller Compact和另一个ExpandedVC
