仅横向应用程序中的GameCenter身份验证会引发UIApplicationInvalidInterfaceOrientation [英] GameCenter authentication in landscape-only app throws UIApplicationInvalidInterfaceOrientation

问题描述

问题：
如果用户未登录GameCenter帐户 - GameCenter身份验证视图以纵向模式启动（在ios 5中有一个模态对话框）要求登录。但是如果我在xcode中禁用纵向模式（项目摘要）或在supportedInterfaceOrientationsForWindow :(因为我的应用程序应该只在横向模式下运行）我得到：

Problem: If user is not logged into GameCenter account - GameCenter authentication view is launched in portrait mode (in ios 5 there were a modal dialog) asking to log in. But if I disable Portrait mode in xcode (Project Summary) or in supportedInterfaceOrientationsForWindow: (as my app supposed to run in landscape mode ONLY) I get:

由于未捕获的异常而终止应用程序' UIApplicationInvalidInterfaceOrientation'，原因：'支持的方向与应用程序没有共同的方向，shouldAutorotate返回YES'

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'

如果我启用了Portrait for ipad / iphone（和/或注释出supportedInterfaceOrientationsForWindow :)它没有崩溃，但我不希望启用纵向模式。

If I enable Portrait for ipad/iphone (and/or comment out supportedInterfaceOrientationsForWindow:) it works without crash, but I don't want portrait mode to be enabled.

推荐答案

在撰写此问题并尝试使用代码时，似乎我找到了一个解决方案：
enable all项目摘要中的方向和删除应用程序：supportedInterfaceOrientationsForWindow。

While writing this question and experimenting with code, it seems that I've found a solution: enable all orientations in project summary and remove application:supportedInterfaceOrientationsForWindow.

将此代码添加到ViewController：

Add this code to ViewController:

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

现在无缝运行。
