自动旋转仅适用于不在设备上的模拟器（IOS 7.1）

Question

我已尝试在此处发布各种方法，以便使用故事板在IOS7中正确设置AutoRotation。我有“应该”工作，因为它在模拟器中运行得非常好但是当我将代码加载到设备（iPad或iPhone）上时它不会旋转。

[更新：代码现在可以在iPad上旋转，但不能在Mini或iPhone上旋转???]

在模拟器（和IPAD）中：

• 导航到控制器：加载正确的方向
• 旋转控制器：仅允许指定方向

在IPHONE / IPAD Mini上：

• 导航至控制器：不更改方向
• 旋转控制器：仅允许指定方向

我不知道有什么区别。如果有人有任何建议，那将是超级有用的，因为它让我疯狂。

我遵循的方法详述如下：

我遵循了某处提到的方法，并创建了一个名为UINavigationController RotationControlledViewController的子类（代码如下）。

然后我制作了LandscapeViewController和PortraitViewController子类UIViewController。视图控制器我希望锁定到从这些类继承而不是UIViewController

的特定方向

（是的 - 我确实确保我的旋转锁已在设备上禁用）

更新 - 其他异常：

在IPAD Mini上，事情并没有完全正常工作我在风景中并导航到“应该”是肖像的视图。它会启动一个纵向对齐的警报，但视图本身会出现景观。见比较：

我注意到屏幕截图是纵向的（警报也是如此）。这对我来说意味着迷你“认为”它在纵向模式，但不知何故它没有正确更新视图控制器

IPAD显然看起来很正确。

我在GitHUB上制作了一个示例项目来演示这个问题：

Answer 1

您似乎遇到的情况与IOS7以后有关。从我所看到的，你所寻求的唯一方法就是用模态segue将第二个导航控制器添加到你的堆栈中。或者，您可以尝试关闭AutoLayout。我认为这些选项都不是你想要听到的。
