crash - SKScene 无法释放内存导致内存增长受限

Question

我已经为此苦苦挣扎了好几天，由于某种原因，我的 SKScene 没有正确释放，这会导致有限的内存增长，因为每次我退出并进入一个场景时，内存都会跳起来。这意味着在说 10 轮游戏后，应用程序崩溃。据我所知，经过大量检查后，我没有任何保留周期或对场景本身的强引用，虽然我知道纹理在预加载后肯定会被缓存并保存在内存中，但内存不应该每次都增加。

这是我在 View Controller 中设置 skview 和第一个场景的方式:

-(void)loadStartScreen{

    SKView *theView = (SKView *) self.view;
    theView.showsFPS = YES;
    theView.showsNodeCount = YES;
    //Sprite Kit applies additional optimizations to improve rendering performance
    theView.ignoresSiblingOrder = YES;

    // Create and configure the scene.
    MainMenuScene *theScene = [MainMenuScene sceneWithSize:theView.bounds.size];
    theScene.scaleMode = SKSceneScaleModeAspectFill;
    theScene.backgroundColor = [UIColor grayColor];

    // Present the scene
    [theView presentScene:theScene];

这是我的 MainMenuScene 中用于创建并移动到下一个场景的代码:

 SKScene *theScene;
    SKTransition *theTransition;
    switch (theTag.intValue) {
        case 0: // start game
            // stop music
            [[appDelegate musicPlayer]stop];
            theScene  = [[GameLevelScene alloc] initWithSize:self.view.bounds.size];
            // transition type
            theTransition = [SKTransition fadeWithDuration:1.0];
            break;
        case 1: // settings
            theScene  = [[SettingsScene alloc] initWithSize:self.view.bounds.size];
            // transition type
            theTransition = [SKTransition flipHorizontalWithDuration:1.0];
            break;
        case 2: // iap
            theScene  = [[IAPScene alloc] initWithSize:self.view.bounds.size];
            // transition type
            theTransition = [SKTransition flipHorizontalWithDuration:1.0];
            break;
        case 3: // unlocks screen
            NSLog(@"scene is %@",self.view.scene);
             theScene  = [[deletmet alloc] initWithSize:self.view.bounds.size];
            // transition type
            theTransition = [SKTransition flipHorizontalWithDuration:1.0];
            NSLog(@"scene is after %@",self.view.scene);
            break;
        case 4: // level complete
            theScene  = [[LevelCompleteScene alloc] initWithSize:self.view.bounds.size];
            // transition type
            theTransition = [SKTransition flipHorizontalWithDuration:1.0];
            break;
        case 5: // cheats
            theScene  = [[CheatsScene alloc] initWithSize:self.view.bounds.size];
            // transition type
            theTransition = [SKTransition flipHorizontalWithDuration:1.0];
            break;

        default:
            break;
    }

现在我知道你应该使用 "[self.view presentScene:]"作为 SkView 保存场景，但因为没有任何工作，我一直在尝试看看为什么场景似乎没有解除分配。当我尝试按下案例 2 的按钮时，我得到了结果 NSlog:

[self presentScene:theScene];

NSLOG 结果 = "IAP SCENE DEALLOC"但用户不会被带到下一个场景。

[self presentScene:nil];

NSLOG 结果 = "IAP SCENE DEALLOC"但用户不会被带到下一个场景。

[self.view presentScene:theScene];

即使当前 MainMenuScene 具有用于 dealloc 的 NSLOG，也没有 nslog 结果

[self.view presentScene:nil];

NSLOG 结果 = IAP SCENE DEALLOC 屏幕变灰

现在这一切都非常奇怪，因为当我确实收到一条 DEALLOC NSLOG 消息时，它应该为我提供当前场景 aka MainMenuScene 的解除分配的 NSLOG，而不是它应该加载的场景。

难道我做错了什么？我是否错误地使用了 SKView，任何帮助将不胜感激，因为我已经阅读了各种没有帮助的帖子。

更新:这是我在之间来回移动的每个场景的代码，注意缺少 Action 或对 self 的任何强烈引用:

我可能是错的，但我怀疑你的按钮类是你的冒犯者。你打电话时...

[testButton4 addTarget:self selector:@selector(buttonPressed:) withObject:[NSNumber numberWithInt:5] forControlEvent:AGButtonControlEventTouchUpInside];

您通过 self是那个场景。在按钮类中，方法..

-(void)addTarget:(id)target selector:(SEL)selector withObject:(id)object forControlEvent:(AGButtonControlEvent)controlEvent
{
    //check whether selector is already saved, otherwise it will get called twice

    if (marrSelectors == nil)
    {
        marrSelectors = [NSMutableArray new];
    }

    NSMutableDictionary *mdicSelector = [[NSMutableDictionary alloc]init];

    [mdicSelector setObject:target forKey:@"target"];
    [mdicSelector setObject:[NSValue valueWithPointer:selector] forKey:@"selector"];

    if (object)
    {
        [mdicSelector setObject:object forKey:@"object"];
    }

    [mdicSelector setObject:[NSNumber numberWithInt:controlEvent] forKey:@"controlEvent"];

    [marrSelectors addObject:mdicSelector];
}

注意这个..

[mdicSelector setObject:target forKey:@"target"];

target 是你的场景，它被放入一个字典中，然后放入一个数组中。所以理论上这个按钮现在对你的场景有很强的引用，你的场景也有对那个按钮的引用。

为了测试这个理论，在调用之前将所有按钮设置为零

[self.view presentScene:theScene transition:theTransition];

如果我是对的，那应该打破对彼此的强引用。希望这有帮助，这就是问题所在。
