Question

我有一个相当简单的应用程序，我有一个问题。它工作正常几秒钟，但过了一会儿，它崩溃了。这是我的代码：

-(id) init
{
    if( (self=[super init] )) {
        self.isTouchEnabled = YES;
        trail = [[CCMotionStreak streakWithFade:3.0f minSeg:1 image:@"streak.png" width:6 length:50 color:ccc4(120, 250, 150, 200)] autorelease];
        [self addChild:trail z:1 tag:2];    
    }
    return self;
}
-(BOOL) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self ccTouchesMoved:touches withEvent:event];
    return YES;
}

-(BOOL)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch = [touches anyObject];
    CGPoint touchLocation = [touch locationInView: [touch view]]; 
    touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
    [trail setPosition:touchLocation]; 
    return YES;
}


-(BOOL)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    return YES;
}

这是来自调试器控制台的会话数据：

崩溃的时候就是它给出了deallocing语句。知道这里发生了什么吗？

其他细节：我尝试用'保留'替换路径初始化中的'autorelease'并将其完全删除，但似乎没有任何区别。

此行中的autorelease会导致问题：

    trail = [[CCMotionStreak streakWithFade:3.0f minSeg:1 image:@"streak.png" width:6 length:50 color:ccc4(120, 250, 150, 200)] autorelease];

streakWithFade:minSeg:image:width:length:color:返回一个自动释放的对象。由于此代码再次自动释放，因此在自动释放池耗尽时会释放太多的释放调用。

cocos2d ios应用程序崩溃没有错误 - 意外dealloc
