ios - Cocos2D pauseAllRunningActions？

Question

我很难在我的 Cocos2D 应用程序中恢复动画。我将 CCSprite 作为子级添加到 CCSpriteBatchNode，它会播放动画。

所以当我点击暂停按钮时，我会这样做:

[[[CCDirector sharedDirector] actionManager] pauseAllRunningActions];

现在在他们说要使用的文档中:

[[[CCDirector sharedDirector] actionManager] resumeTargets:];

但是，我已经尝试了所有可能的目标，包括 Sprite 本身、batchnode、self (CCLayer) 和当前的 CCScene，但没有任何效果。

是否有某种方法可以恢复所有目标？

编辑:我在 Singleton 中声明了一个 NSSet 并且我这样做了:

[Singleton sharedSingleton].pauseTargets = [[[CCDirector sharedDirector] actionManager] pauseAllRunningActions];
[[[CCDirector sharedDirector] actionManager] pauseAllRunningActions];

然后我继续:

[[[CCDirector sharedDirector] actionManager] resumeTargets:[Singleton sharedSingleton].pauseTargets];

但是我崩溃了:

Answer 1

存储暂停的目标

NSSet *pausedTargets = [[NSSet alloc] initWithSet:[[[CCDirector sharedDirector] actionManager] pauseAllRunningActions]];

恢复暂停的目标

[[[CCDirector sharedDirector] actionManager] resumeTargets:pausedTargets];

此外，不要忘记在取消暂停后释放 pausedTargets。
