Question

我在更改场景时难以解决崩溃问题。这是被替换的场景的dealloc方法。它被调用，我知道没有内存泄漏或堆膨胀。任何人都可以建议我可能犯的愚蠢/明显的错误。我为白痴道歉。

-(void) dealloc
{
NSLog(@"Dungeon.m dealloc called");

[self removeAllChildrenWithCleanup:true];
[self unscheduleAllSelectors];
[[CCScheduler sharedScheduler]unscheduleAllSelectors];

if (entityList) [entityList release];
if (lopsidedList) [lopsidedList release];
if (monsterNames) [monsterNames release];
if (menuSprites) [menuSprites release];
if (menuLabels) [menuLabels release];
if (monsterLevels) [monsterLevels release];
if (theMagicFactory) [theMagicFactory release];
if (theDM) [theDM release];
if (theDisplay) [theDisplay release];
if (aDungeonLevel) [aDungeonLevel release];
NSLog([NSString stringWithFormat:@"Player Retain Count: %i",[thePlayer retainCount]]);

[super dealloc]
}

我已经确认调用了重要列出的对象的deallocs：

2012-09-09 10:51:31.840 Pocket Dungeons[947:707] Dungeon.m dealloc called
2012-09-09 10:51:31.878 Pocket Dungeons[947:707] DungeonMaster.m dealloc called.
2012-09-09 10:51:31.910 Pocket Dungeons[947:707] DungeonDisplay.m dealloc called
2012-09-09 10:51:31.915 Pocket Dungeons[947:707] dungeonlevel.m dealloccalled

这是不断变化的场景代码：

            else if (whatIsHere==STAIRS_UP) {
                if (thePlayer.currentDungeonLevel==1) {
                    NSLog([NSString stringWithFormat:@"Self Retain Count: %i",[self retainCount]]);
                    thePlayer.theDungeon = nil;
                    theDM.theDungeon = nil;
                    theDisplay.theDungeon = nil;

                    for (int i=0; i<[aDungeonLevel.mArray count]; i++) {
                        Monster *aMonster = [aDungeonLevel.mArray objectAtIndex:i];
                        aMonster.theDungeon = nil;
                    }


                    NSLog([NSString stringWithFormat:@"Self Retain Count: %i",[self retainCount]]);
//                    CCScene *aScene = [Town nodeWithPlayer:thePlayer];
                    CCScene *aScene = [CharacterMaker2 nodeWithPlayer:thePlayer];
                    [[CCDirector sharedDirector] replaceScene:aScene];

这是发生崩溃的地方：

感谢。

Answer 1

希望我可以充分回答我自己的问题，尽管答案可以使用一些进一步的输入。

我认为问题在于cocos2d正在发布＆＃34;正在运行的场景＆＃34;来自CCDirector：setNextScene，在我允许它被解除分配之后。通过仔细检查我的发布和保留，我能够让它保留更长时间，以便让cocos2d有时间进行管理。

我过于热心地试图不在任何地方保留我的物品，因为我使用了CCScheduler UnscheduleAllSelectors，这对像我这样的普通人来说是禁忌。对我来说，最重要的是：当你试图纠正它时，小心不要搞砸你的代码;并保持耐心：逻辑是合乎逻辑的。另外，我学会了访问cocos2d源代码来帮助我，并且在使用这些乐器方面也获得了更好的技巧，尤其是对堆的检查。
