SKScene 无法释放内存，导致内存增长受限
SKScene Fails to deallocate memory resulting in bounded memory growth
几天来我一直在为此苦苦挣扎，由于某种原因，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，内存都会跳起来。这意味着在进行了 10 轮游戏后，应用程序崩溃了。据我所知，经过多次检查后，我没有任何保留周期或对场景本身的强引用，虽然我知道纹理被缓存并保存在内存中，但一旦预加载，内存不应该每次都增加。
这就是我在 viewcontroller 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 中用于创建和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:]”，因为 SkView 持有场景，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 NSlogs:
[self presentScene:theScene];
NSLOG 结果 = "IAP SCENE DEALLOC" 但用户没有被带到下一个场景。
[self presentScene:nil];
NSLOG 结果 = "IAP SCENE DEALLOC" 但用户没有被带到下一个场景。
[self.view presentScene:theScene];
即使当前 MainMenuScene 有 dealloc 的 NSLOG，也没有 nslog 结果
[self.view presentScene:nil];
NSLOG 结果= IAP SCENE DEALLOC 并且屏幕变灰
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，它应该给我当前场景的 dealloc 的 NSLOG，也就是 MainMenuScene，而不是它应该加载的场景。
我做错了什么吗？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帖子，所有这些都没有帮助。
- 更新：这是我在每个场景之间来回移动的代码，请注意缺少动作或任何对自身的强引用：

根据您发布的代码，我建议您将此添加到您的 MainMenu：

[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;
}
将此添加到您的 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 使用您无法控制的自己的缓存。这意味着您会在切换场景的前几次看到内存增加，但会在某个时候趋于平稳。我建议你来回移动15到20次，看看会发生什么。
在我正在开发的游戏中，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()
}
每一关都是一个场景，继承了这个方法。 （我有一个GameScene.swift，每一层都是它的子类）
每个级别的方法如下所示：
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)
}
显然这是 swift 并且您的游戏在 Objective C 但希望您明白了。
我可能是错的，但我怀疑你的按钮 class 是你的冒犯者。当你打电话...

注意这个..
[mdicSelector setObject:target forKey:@"target"];
target 是你的场景，它被扔进一个字典，然后被扔进一个数组。所以理论上那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。
为了验证这个理论，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，那应该打破彼此之间的强引用。希望这会有所帮助，这就是问题所在。
几天来我一直在为此苦苦挣扎，由于某种原因，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，内存都会跳起来。这意味着在进行了 10 轮游戏后，应用程序崩溃了。据我所知，经过多次检查后，我没有任何保留周期或对场景本身的强引用，虽然我知道纹理被缓存并保存在内存中，但一旦预加载，内存不应该每次都增加。
这就是我在 viewcontroller 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 中用于创建和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:]”，因为 SkView 持有场景，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 NSlogs:
[self presentScene:theScene];
NSLOG 结果 = "IAP SCENE DEALLOC" 但用户没有被带到下一个场景。
[self presentScene:nil];
NSLOG 结果 = "IAP SCENE DEALLOC" 但用户没有被带到下一个场景。
[self.view presentScene:theScene];
即使当前 MainMenuScene 有 dealloc 的 NSLOG，也没有 nslog 结果
[self.view presentScene:nil];
NSLOG 结果= IAP SCENE DEALLOC 并且屏幕变灰
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，它应该给我当前场景的 dealloc 的 NSLOG，也就是 MainMenuScene，而不是它应该加载的场景。
我做错了什么吗？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帖子，所有这些都没有帮助。
- 更新：这是我在每个场景之间来回移动的代码，请注意缺少动作或任何对自身的强引用：

根据您发布的代码，我建议您将此添加到您的 MainMenu：

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;
}
将此添加到您的 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 使用您无法控制的自己的缓存。这意味着您会在切换场景的前几次看到内存增加，但会在某个时候趋于平稳。我建议你来回移动15到20次，看看会发生什么。
在我正在开发的游戏中，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()
}
每一关都是一个场景，继承了这个方法。 （我有一个GameScene.swift，每一层都是它的子类）
每个级别的方法如下所示：
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)
}
显然这是 swift 并且您的游戏在 Objective C 但希望您明白了。
我可能是错的，但我怀疑你的按钮 class 是你的冒犯者。当你打电话...
[testButton4 addTarget:self selector:@selector(buttonPressed:) withObject:[NSNumber numberWithInt:5] forControlEvent:AGButtonControlEventTouchUpInside];
你通过了self那个场景。在按钮class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，它被扔进一个字典，然后被扔进一个数组。所以理论上那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。
为了验证这个理论，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，那应该打破彼此之间的强引用。希望这会有所帮助，这就是问题所在。
