c++ - Cocos2d replaceScene 不释放旧场景

Question

我有一个有多个级别的 box2d-cocos2d 游戏。我的关卡是使用从另一个类继承的 Box2d 功能的图层。例如第一层看起来像:

Level1Layer : Box2DLevel : Box2DLayer : CCLayer : CCNode : NSObject

我的问题是层没有在应该释放的时候释放。例如，如果我用这段代码重放关卡:

[[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:0.5f scene:[[self class] node]]];

然后内存占用量就会增加。如果我有一个像菜单这样的圆圈，同样的事情也会发生 -> Level 1 -> menu -> Level 1 并且我的应用程序在一段时间后因为内存不足而崩溃。我跟踪了 dealloc使用 NSLogs 的方法，但是当我替换场景时，每个 dealloc 方法都会被调用。 我的日志看起来像:

*** DEALLOC ***<Level1Layer = 0x1cdcfe70 | Tag = -1>
2013-08-26 12:05:57.089 Myapp[6334:907] 
***BOX2DLEVEL DEALLOC ***<Level1Layer = 0x1cdcfe70 | Tag = -1>
2013-08-26 12:05:57.093 Myapp[6334:907] ***BOX2DLAYER DEALLOC ***
<Level1Layer = 0x1cdcfe70 | Tag = -1> 

我真的卡住了，因为在 iPhone 4 上玩了 3 个关卡后应用程序崩溃了。 我怎么解决这个问题？任何解决方案和指针表示赞赏。

1 级释放:

-(void)dealloc{
    NSLog(@"\n*** DEALLOC ***%@",self);
    [self removeAllChildrenWithCleanup:YES];
    [super dealloc];
}

Box2dLevel 释放:

-(void) dealloc{
    NSLog(@"\n***BOX2DLEVEL DEALLOC ***%@",self);
    [self removeChild:_label cleanup:YES];
    [self removeChild:labelForCoins cleanup:YES];
    [self removeChild:labelForTime cleanup:YES];
    [self removeChild:freezeCountDown cleanup:YES];
    [self removeChild:freezedMask cleanup:YES];
    [self removeChild:_backGround cleanup:YES];
    [self removeChild:darkLayer cleanup:YES];
    [self removeChild:flashlayer cleanup:YES];
    [self removeChild:skillsMenu cleanup:YES];
    [arrayForObjects release];
    [skillsMenuArray release];
    [super dealloc];
}

Box2dLayer 释放:

-(void) dealloc
{
    NSLog(@"***BOX2DLAYER DEALLOC ***\n%@",self);
    if (debugDraw) {
        delete debugDraw;
        debugDraw = NULL;
    }
    if (mouseJoint) {
        world->DestroyJoint(mouseJoint);
        mouseJoint = NULL;
    }
    if (groundBody) {
        world->DestroyBody(groundBody);
        groundBody = NULL;
    }
    if (referenceBody) {
        world->DestroyBody(referenceBody);
        referenceBody = NULL;
    }
    if (bombSensor) {
        world->DestroyBody(bombSensor);
        bombSensor = NULL;
    }
    if (laserSensor) {
        world->DestroyBody(laserSensor);
        laserSensor = NULL;
    }
    if (_contactListener) {
        free(_contactListener);
        _contactListener = NULL;
    }
    [self removeChild:_obj cleanup:YES];
    [super dealloc];
    NSLog(@"\n***Box2dLayer superclass deallocated");

尝试使用[Level1layer scene]代替[[self class] node](示例项目也是这样做的)
