旋转IOS模拟器与现实

Question

我遇到了 Storyboards AutoRotation 和 iPhone 的问题。我已经将一个非常简单的项目与 3 个视图控制器放在一起，我将其上传到 gitHub 以演示该问题

我已在以下设备上对此进行了测试：

• IPAD 3
• iPhone 5s
• 模拟器（iphone / ipad）

在 iPad 和模拟器 (Iphone/Ipad) 上似乎一切正常，但是当我在 5s 上运行它时，它无法正确旋转。

在 iPhone 上，它会旋转警报视图，但不会旋转它出现的视图控制器

在模拟器上这是结果（看起来正确）

示例项目的代码可以在：
https://github.com/jlss/RotationIssues

我很高兴并愿意尝试任何人的任何建议。

注意事项：（我正在使用电话 objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeLeft); ）但据我所知，这应该没问题。

最后我有一个简单的故事板：

Answer 1

很遗憾，如果您使用的是 push segues，您将无法做到这一点。你必须使用模态。
