旋转IOS模拟器与现实

Question

我遇到了Storyboard AutoRotation和iPhone的问题。我已经整理了一个非常简单的项目，有3个视图控制器，我上传到gitHub来演示问题

我在以下设备上测试了这个：

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

一切似乎在iPad和iPad上完美运行模拟器（Iphone / Ipad），但是当我在5s上运行它时，它无法正确旋转。

在iPhone上，它将旋转警报视图，但不会显示它出现的视图控制器

在模拟器上这是结果（看起来正确）

示例项目代码可在以下位置找到：

我很高兴并愿意尝试任何人提出的任何建议。

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

不幸的是，如果您使用push segues，则无法执行此操作。你必须使用模态。
