Question

快速提问，我到处寻找答案无济于事。我有一个stroyboard加载tabViewController作为初始视图。第一个选项卡是自动选择和加载的（这就是我想要的）。我以编程方式定制了此视图的布局。它有一个UIImage和6个UIButtons。我在代码中以proprotionately调整了一切。当ViewController加载时，它不会应用我的编程格式。如果我离开选项卡或选择一个按钮，然后返回到ViewController，那里的格式正确 IS 。我不明白为什么它不加载我编程的格式开始。我通过调用函数在viewDidLoad中初始化了格式但是它仍然加载了storyboard布局。请指教。

谢谢你

Answer 1

好的，所以我发现了问题。当编译器进入orientationAdjust初始构建时的方向值是UIDeviceOrientationUnknown所以我添加了

else if (orientation == UIDeviceOrientationUnknown)

条件与我想要的格式。这加载了我需要的视图。

感谢大家为我调查此事。
