作为说按这里 LearnCocos2D ：

  而应用程序进入后台

问题是AVAudioSession不能活动。

  
  

解决方法是相当简单，而且也适用于ObjectAL =>设置AVAudioSession为无效，而应用程序是在后台，当应用程序进入前景激活音频会话。

  
  

此修复程序简化的AppDelegate看起来像这样：

块引用>

 ＃进口＆LT; AVFoundation / AVFoundation.h＆GT;... - （无效）applicationWillResignActive：（UIApplication的*）的应用
{
    // prevent音频崩溃
    [AVAudioSession sharedInstance] SETACTIVE：没有错误：无];
} - （无效）applicationDidEnterBackground：（UIApplication的*）的应用
{
    // prevent音频崩溃
    [AVAudioSession sharedInstance] SETACTIVE：没有错误：无];
} - （无效）applicationWillEnterForeground：（UIApplication的*）的应用
{
    //恢复音频
    [AVAudioSession sharedInstance] SETACTIVE：YES错误：无];
}
 

  

PS：此修复程序将包含在狗头包v7.0.3

I tried to search everywhere in the code:Explained documentry what it does when going to background, or if it is even paused sometime, but to no avail- can someone direct me in the way of what is recommended to do when going to background in sprite kit enabled game?

Should I just call scene.paused = YES, or how can I confirm that no drawing occurs in background so I can avoid termination by iOS which won't allow me that?

Thanks!

As said here by LearnCocos2D:

The problem is AVAudioSession can't be active while the app enters background.

The fix is quite simple, and also applies to ObjectAL => set the AVAudioSession to inactive while the app is in background, and reactivate the audio session when the app enters foreground.

A simplified AppDelegate with this fix looks like so:

#import <AVFoundation/AVFoundation.h>

...

- (void)applicationWillResignActive:(UIApplication *)application
{
    // prevent audio crash
    [[AVAudioSession sharedInstance] setActive:NO error:nil];
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    // prevent audio crash
    [[AVAudioSession sharedInstance] setActive:NO error:nil];
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    // resume audio
    [[AVAudioSession sharedInstance] setActive:YES error:nil];
}

PS: this fix will be included in Kobold Kit v7.0.3.
