【问题描述】:
我正在一个 cocos2d 游戏项目中实现 Game Kit。
游戏仅横向。 gamekit 也应该如此。
当我展示用于匹配的 gamekit 模态视图控制器时,它以横向显示。但是底层的 cocos2d CCLayer 变成了纵向。
rootViewContollers 定位代码如下所示:
// Override to allow orientations other than the default portrait orientation.
- (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 ( UIInterfaceOrientationIsLandscape(interfaceOrientation) );
#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;
}
如果我将 GAME_AUTOROTATION 定义为 kGameAutorotationUIViewController 或 kGameAutorotationCCDirector 或 kGameAutorotationNone 没有区别
