的cocos2d的Xcode - SLComposeViewController黑屏

我有一个cocos2d的游戏，我一直在努力，我已经成功地得到它通过创建一个按钮在屏幕上像这样为呈现SLComposeViewController：的cocos2d的Xcode - SLComposeViewController黑屏

的头文件是这样的：

@interface HighScores : Main 
@end 

@interface socialViewControllerAtTheBottomOfThisClass : UIViewController 
@end

.m文件中的代码：

@implementation HighScores 
- (init) { 
UIButton *shareButton = [[UIButton alloc] initWithFrame:CGRectMake(screenWidth/2, screenHeight/2, 100, 30)]; 
[shareButton addTarget:self action:@selector(shareAction) forControlEvents:UIControlEventTouchUpInside]; 
} 

- (void)shareAction { 

// I created a ViewController class at the end of the .m file containing the social stuff 
// but I did this and managed to get it to present the SLComposeViewController: 

socialViewControllerAtTheBottomOfThisClass *bottomController = [[socialViewControllerAtTheBottomOfThisClass alloc] init]; 
[[[[CCDirector sharedDirector] openGLView] window] setRootViewController:bottomController]; 
[bottomController shareToFacebook]; 

} 
} 
@end

然后在底部的视图控制器实现：

@implementation socialViewControllerAtTheBottomOfThisClass 

- (void)shareToFacebook { 
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) { 

SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; 
[controller setInitialText:@"This is my facebook status!"]; 

[self presentViewController:controller animated:YES completion:nil]; 

controller.completionHandler = ^(SLComposeViewControllerResult result) { 
switch(result) { 
case SLComposeViewControllerResultCancelled: [self actionForCancelled]; 
break; 
case SLComposeViewControllerResultDone: [self actionForDone]; 
break; 
}}; 

} 
} 

- (void)actionForCancelled { 
} 
- (void)actionForDone { 
} 

@end

该代码提供了SLComposeViewController，但呈现时，我得到一个黑色背景，点击Post或Cancel后，屏幕保持黑屏。我正在考虑将rootViewController设置为HighScores，但是由于它不是ViewController，我无法做到这一点。

我已经设法通过运行[[CCDirector shareDirector] replaceWithScene：[Game scene]]来显示白色屏幕; – iOSDec

不要更改根视图控制器。试试像在[[CCDirector sharedDirector] openGLView]上的其他视图控制器一样呈现它。 –

试过这个家伙，我的Cocos2d版本老了 - 所以要做到这一点我必须做的：[[[CCDirector sharedDirector] openGLView] window] rootViewController] presentViewController：controller animated：YES completion：nil]; 但由于某种原因，它不会呈现它？任何想法哈哈？ – iOSDec

我没有在那里我在现在的代码，但我相信在我创建了SLComposeViewController并将其添加为类似于子视图过去：

[[[CCDirector sharedDirector] openGLView] addSubView:controller.view];

，并删除它，你会必须删除子视图。你也可以尝试：

AppController* app = (AppController*) [[UIApplication sharedApplication] delegate]; 
[[app navController] presentModalViewController:controller animated:YES];
