iOS 6游戏中心崩溃的身份验证 [英] iOS 6 Game Center Crash on Authentication

问题描述

我在Cocos2d-iPhone中构建一个游戏，当我更新到iOS 6时，我注意到苹果改变了Game Center身份验证的方式，使用 authenticateHandler 而不是 authenticateWithCompletionHandler 。

我添加了新的身份验证方法，但如果玩家尚未登录游戏中心，游戏现在会崩溃。如果用户已经登录，没有问题。

这是我的代码：

  if（SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO（@6.0））
 {
 GKLocalPlayer * localPlayer = [GKLocalPlayer localPlayer]; 
 localPlayer.authenticateHandler = ^（UIViewController * viewController，NSError * error）
 {
 if（viewController！= nil）
 {
 AppController * appDelegate = ）[UIApplication sharedApplication] .delegate; 
 
 [delegate.viewController presentViewController：viewController animated：YES completion：nil]; 
} 
 else if（localPlayer.isAuthenticated）
 {
 NSLog（@Player authenticated）; 
} 
 else 
 {
 NSLog（@Player authentication failed）; 
} 
}; 
} 
  

看起来像在试图呈现Game Center viewController时崩溃，我使用完全相同的代码来呈现 GKTurnBasedMatchmakerViewController 没有问题。

任何帮助将非常感谢。 / p>

编辑：
以下是在崩溃时抛出的异常：

未捕获异常UIApplicationInvalidInterfaceOrientation：支持的方向与应用程序没有通用方向，shouldAutorotate正在返回YES

$

解决方案

在这里你可以找到有关崩溃的有用信息，我认为这是根本原因。

应用程式应提供委托方法应用程式：supportedIntefaceOrientationsForWindow，并确保肖像是

 
 
 $ b 
 code>  - （NSUInteger）application：（UIApplication *）application supportedInterfaceOrientationsForWindow：（UIWindow *）window 
 {
 return UIInterfaceOrientationMaskAllButUpsideDown; 
} 
  

I am building a game in Cocos2d-iPhone, and while I was updating to iOS 6, I noticed that Apple changed the way Game Center authentication is done, using authenticateHandler instead of authenticateWithCompletionHandler.

I added the new authentication method, but the game now crashes if a player is not already logged in to Game Center. There is no problem authenticating if a user is already logged in.

Here is my code:

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0"))
{
    GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
    localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error)
    {
        if (viewController != nil)
        {
            AppController *appDelegate = (AppController*)[UIApplication sharedApplication].delegate;

            [delegate.viewController presentViewController:viewController animated:YES completion:nil];
        }
        else if (localPlayer.isAuthenticated)
        {
            NSLog(@"Player authenticated");
        }
        else
        {
            NSLog(@"Player authentication failed");
        }
    };
}

It seems like it's crashing when trying to present the Game Center viewController, even though I use the exact same code to present the GKTurnBasedMatchmakerViewController with no issues.

Any help would be much appreciated.

EDIT: Here is the exception getting thrown on crash:

Uncaught Exception UIApplicationInvalidInterfaceOrientation: Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES

解决方案

Here you can find useful information about your crash, I think it is the underlying reason. https://developer.apple.com/library/ios/#releasenotes/General/RN-iOSSDK-6_0/_index.html

Apps should provide the delegate method application:supportedIntefaceOrientationsForWindow and ensure that portrait is one of the returned mask values.

I added below code to fix this crash.

- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}
