【问题描述】:
所以我最近从客户那里听说了一个奇怪的问题。当他们尝试旋转屏幕时,屏幕会变黑。这似乎只是 iOS 8 的事情,因为我的最新版本只是将 iOS 8 添加到组合中。
从我的视图控制器:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
//
// There are 2 ways to support auto-rotation:
// - The OpenGL / cocos2d way
// - Faster, but doesn't rotate the UIKit objects
// - The ViewController way
// - A bit slower, but the UiKit objects are placed in the right place
//
#if GAME_AUTOROTATION==kGameAutorotationNone
//
// EAGLView won't be autorotated.
// Since this method should return YES in at least 1 orientation,
// we return YES only in the Portrait orientation
//
return ( interfaceOrientation == UIInterfaceOrientationPortrait );
#elif GAME_AUTOROTATION==kGameAutorotationCCDirector
//
// EAGLView will be rotated by cocos2d
//
// Sample: Autorotate only in landscape mode
//
if( interfaceOrientation == UIInterfaceOrientationLandscapeLeft ) {
[[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeRight];
} else if( interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
[[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeLeft];
}
// Since this method should return YES in at least 1 orientation,
// we return YES only in the Portrait orientation
return ( interfaceOrientation == UIInterfaceOrientationPortrait );
#elif GAME_AUTOROTATION == kGameAutorotationUIViewController
//
// EAGLView will be rotated by the UIViewController
//
// Sample: Autorotate only in landscpe mode
//
// return YES for the supported orientations
return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) );
#else
#error Unknown value in GAME_AUTOROTATION
#endif // GAME_AUTOROTATION
// Shold not happen
return NO;
}
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskLandscape;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
我能够在我的设备和模拟器上重现它......
横向左侧 肖像 横向右
根据这个类似的 iPad 测试,我可以判断的是,图像实际上会自行旋转离开屏幕。即使游戏是横向的,我目前也允许所有 4 个方向,因为我正在使用游戏中心,并且至少一些较旧的 iOS 需要纵向登录。我使用的是相当旧的 cocos2d 版本(v1.1.0-beta2b),但我以前从未经历过这样的事情。我可能只是更改支持的方向并关闭自动旋转,但我想修复它。这是怎么回事?
