ios - Cocos2d Xcode - SLComposeViewController 黑屏

Question

我有一个我一直在开发的 Cocos2d 游戏，我已经设法通过在屏幕上创建一个按钮来让它显示 SLComposeViewController，如下所示:

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 ViewController 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

代码显示了 SLComposeViewController，但在显示时，我得到了黑色背景，在我点击发布或取消后，屏幕保持黑色。我正在考虑将 rootViewController 设置为 HighScores，但鉴于它不是 ViewController，我无法做到这一点。

我现在没有代码，但我相信过去我创建了 SLComposeViewController 并将其添加为类似于以下的 subview :

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

要删除它，您必须删除 subview 。您也可以尝试:

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