添加UIViewController会使屏幕方向混乱 [英] Adding UIViewController messes up screen orientation

问题描述

我从一个GLSprite示例应用开始(源代码)，然后通过添加

I started with a GLSprite sample app (source code), then added a UIViewController by adding

UIViewController *vc = [[UIViewController alloc] init];
vc.view = glView;
self.window.rootViewController = vc;
[window makeKeyAndVisible];

到GLSpriteAppDelegate::applicationDidFinishLaunching.的末尾控制器似乎正在工作，因为现在我可以弹出游戏中心窗口，但是它弄乱了我的屏幕orientation.该应用程序在portrait中效果很好，但在所有其他rotations中，它的侧面错误地带有白色条，就像其中一个视图旋转了90度一样.

to the end of GLSpriteAppDelegate::applicationDidFinishLaunching. The controller seems to be working as now I can pop up gamecenter windows, but it has messed up my screen orientation. The app is fine in portrait, but in all other rotations it incorrectly has white bars on the side, like one of the views is rotated 90 degrees.

我在EAGLView::initWithCoder中执行[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];，然后尝试将其移到applicationDidFinishLaunching的末尾，但是它具有相同的行为.

I was doing [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight]; in EAGLView::initWithCoder, I then tried moving it to the end of applicationDidFinishLaunching but it had the same behavior.

任何人都可以帮忙吗?我该怎么做才能解决或调试此问题?谢谢！

Can anyone help? What can I do to fix or debug this? Thank you!

推荐答案

问题是新的UIViewController正在旋转，而我的游戏需要始终显示纵向屏幕.要修复，我创建了一个自定义的viewcontroller并实现了

The issue was the new UIViewController was rotating, when my game expects an always portrait screen. To fix I created a custom viewcontroller and implemented

- (BOOL)shouldAutorotate
{
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return 0;
}
