Landscape Apps Xcode 5 / iOS 7
提问by Teofilo Israel Vizcaino Rodrig
I have a piano app in the App Store. It works in landscape mode.
我在 App Store 中有一个钢琴应用程序。它在横向模式下工作。
Now iOS 7 appears to be ignoring the Landscape setting in IB
现在 iOS 7 似乎忽略了 IB 中的 Landscape 设置
The app works as expected in iOS 6 and below, in landscape. In iOS 7 appears in portrait. Here are settings and relevant code:
该应用程序在 iOS 6 及更低版本中按预期运行。在 iOS 7 中以纵向出现。以下是设置和相关代码：
//iOS 6+
- (BOOL)shouldAutorotate

return YES;
}
//iOS 6+
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight);
}
//iOS 5.1.1-
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

Thanks to @shawnwall comment I realised I didn't have a Root View Controller. In the past my app given support yo iOS 3.1.3 O_O:
感谢@shawnwall 评论，我意识到我没有根视图控制器。过去，我的应用程序支持 iOS 3.1.3 O_O：
[self.window addSubview:self.viewController.view];
I dropped 3.1.3 support a long time ago, so I can set up a root view controller:
我很久以前就放弃了 3.1.3 支持，所以我可以设置一个根视图控制器：
self.window.rootViewController = self.viewController;
That was the thing that caused the visual bug.
这就是导致视觉错误的原因。
