ios - Autorotation 仅适用于模拟器而不适用于设备(​​IOS 7.1)

Question

我尝试了此处发布的各种方法，以使用 Storyboard在 IOS7 中正确设置 AutoRotation。我所拥有的“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 而不是 Mini 或 iPhone 上旋转？？？]

在模拟器(和 IPAD)中:

• 导航到 Controller :加载正确的方向
• 旋转 Controller :只允许指定方向

在 IPHONE/IPAD Mini 上:

• 导航到 Controller :不改变方向
• 旋转 Controller :只允许指定方向

我不知道有什么区别。如果有人有任何建议，那将非常有帮助，因为它让我发疯。

我采用的方法详述如下:

我按照某处提到的方法创建了 UINavigationController 的子类，名为 RotationControlledViewController(代码如下)。

然后我制作了 LandscapeViewController 和 PortraitViewController，它们是 UIViewController 的子类。我想锁定到特定方向的 View Controller 继承自这些类而不是 UIViewController

(是的 - 我确实确保我的旋转锁在设备上被禁用)

更新 -- 其他异常:

在无法正常工作的 IPAD Mini 上，我处于横向模式并导航到“应该”为纵向的 View 。它会启动纵向对齐的警报，但 View 本身会出现横向。查看比较:

我注意到屏幕截图以纵向显示(警报也是如此)。这对我来说意味着迷你“认为”它处于纵向模式，但不知何故它没有正确更新 View Controller 。

IPAD 显然看起来是正确的。

我在 GitHUB 上做了一个示例项目来演示这个问题:

Answer 1

您遇到的情况似乎与 IOS7 以上版本有关。据我所见，完成您所寻求的唯一方法是使用模态转场将第二个导航 Controller 实际添加到您的堆栈中。或者，您可以尝试关闭 AutoLayout。我认为这两种选择都不是您想听到的。
