我一直在努力解决这个问题，因为某些原因我的SKScenes没有正确解除分配，这导致内存增长有限，因为每次我退出并进入场景时内存会跳起来。这意味着在玩了10轮比赛之后App崩溃了。据我所知，经过多次检查，我没有任何保留周期或对场景本身的强烈引用，虽然我知道纹理被缓存并保存在内存中，一旦预加载，内存不应该上升每一次。
这就是我在viewcontroller中设置skview和第一个场景的方法：
-(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中的代码，用于创建并移动到下一个场景：
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＆＃34; [self.view presentScene：]＆＃34;因为SkView掌握了这个场景，但由于没有任何工作，我一直在试验为什么这个场景似乎没有解除分配。当我尝试按下案例2的按钮后，我得到了结果的NSlog：
[self presentScene:theScene];
NSLOG结果=＆＃34; IAP SCENE DEALLOC＆＃34;但用户不会被带到下一个场景。
[self presentScene:nil];
NSLOG结果=＆＃34; IAP SCENE DEALLOC＆＃34;但用户不会被带到下一个场景。
[self.view presentScene:theScene];
即使当前的MainMenuScene具有针对dealloc的NSLOG
，也没有nslog结果[self.view presentScene:nil];
NSLOG结果= IAP SCENE DEALLOC，屏幕变为灰色
现在这一切都非常奇怪，当我得到一个DEALLOC NSLOG消息时，它应该给我NSLOG用于当前场景的dealloc，即MainMenuScene，而不是它应该加载的场景。
我做错了吗？我正在使用SKView错误，任何帮助将不胜感激，因为我已经阅读了各种帖子，所有这些都没有帮助。

我可能错了，但我怀疑你的按钮类是你的罪犯。当你打电话......
[testButton4 addTarget:self selector:@selector(buttonPressed:) withObject:[NSNumber numberWithInt:5] forControlEvent:AGButtonControlEventTouchUpInside];
你传递self成为那个场景。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];
}
请注意..
[mdicSelector setObject:target forKey:@"target"];
目标是你的场景，它被扔进一个被扔进阵列的字典里。因此理论上，按钮现在具有对场景的强引用，并且您的场景具有对该按钮的引用。
为了测试这个理论，在调用
之前将所有按钮设置为nil[self.view presentScene:theScene transition:theTransition];
如果我是正确的，应该打破对彼此的强烈引用。希望这有助于解决问题。
答案 1 :(得分：0)
根据您发布的代码，我建议您将其添加到MainMenu：
-(void) willMoveFromView:(SKView *)view {
[self removeAllChildren];
backgroundImage = nil;
topBar = nil;
bottomBar = nil;
ladybirds = nil;
title = nil;
subtitle = nil;
coffee = nil;
settingsWin = nil;
iapWin = nil;
unlocksWin = nil;
startButton = nil;
continueButton = nil;
settingsButton = nil;
iapButton = nil;
unlocksButton = nil;
theParticles = nil;
}
将其添加到您的SettingsScene：
-(void) willMoveFromView:(SKView *)view {
[self removeAllChildren];
backButton = nil;
resetButton = nil;
resetTutorialsButton = nil;
creditsButton = nil;
titleLabel = nil;
copyrightLabel = nil;
resetGameAlert = nil;
resetTutAlert = nil;
theScene = nil;
theTransition = nil;
menuBg = nil;
}
请记住，SK使用自己无法控制的缓存。这意味着您在切换场景的前几次会看到内存增加，但在某些时候会升级。我建议你来回移动15至20次，看看会发生什么。
答案 2 :(得分：0)
在我正在进行的游戏中，我有一种方法可以进入下一个场景。它看起来像这样：
func proceedToNextLevel() {
// Go to next level
self.physicsWorld.removeAllJoints()
self.enumerateChildNodesWithName("cube", usingBlock: {
(node: SKNode!, stop: UnsafeMutablePointer <ObjCBool>) -> Void in
// do something with node or stop
node.removeFromParent()
})
player.removeFromParent()
hud.removeFromParent()
}
每个级别都是继承此方法的场景。 （我有一个GameScene.swift，每个级别都是它的子类）
每个级别的此方法如下所示：
override func proceedToNextLevel() {
super.proceedToNextLevel()
let transition = SKTransition.revealWithDirection(SKTransitionDirection.Right, duration: 3)
let newScene: LevelFourScene = LevelFourScene.unarchiveFromFile("LevelFourScene") as! LevelFourScene
newScene.scaleMode = SKSceneScaleMode.AspectFit
self.view?.presentScene(newScene)
}
显然这很快，你的游戏是在Objective C中，但希望你能得到这个想法。
