Ios 紧凑型<--&燃气轮机；通过旋转进行常规大小更改=以编程方式使用自动布局时无法同时满足约束

我以编程方式定义了四个按钮，并将它们添加到UIStackview名称“finalStack”中。在旋转过程中，我能够成功更改finalStack方向，但在调整中心定位值后无法移动它。在控制台中，我有一些错误，指出我未能删除前面的约束。我取消激活约束的代码是否不正确，或者我是否遗漏了其他内容？if/else语句中的两个print语句告诉我，在旋转设备后，我正确地命中了相应的代码块

与此同时，我正试图遵循这些建议，并尝试实现符号断点，但这一主题正成为我的另一项主要任务。如果您能深入了解这两个主题，我将不胜感激
