所以我最近听到了客户关于一个奇怪问题的消息。当他们试图旋转屏幕时,屏幕会变黑。这似乎是iOS 8的东西,因为我的最新版本只是添加iOS 8。
来自我的viewcontroller:
- (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....
左侧风景 肖像 景观正确
据我所知,基于此类似的iPad测试,图像实际上是在屏幕上自动旋转。我目前允许所有4个方向,即使游戏是在风景中,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。我正在使用相当旧版本的cocos2d(v1.1.0-beta2b),但我以前从未经历过这样的事情。我可以只改变支持的方向并关闭自动旋转,但我想修复它。这是怎么回事?
答案 0 :(得分:6)
当我为ios8编译时,我也遇到了cocos1.0的问题。在我的代码中,我发现我确实有一个用作根视图控制器的UIViewController(它的子节点在Cocos2D使用的EAGLView中)。
我找到的修复是从我的UIViewController
注释以下方法-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
我已经对ios8和ios7进行了快速测试,并且可以正常运行
