memory-leaks - CCTexture2D 内存泄漏

Question

任何人都可以回答，我应该改变精灵图像，我用我的功能来做

-(void) openKeyWithSprite:(id) sender withSpriteName:(NSString*)spriteName

这会导致内存泄漏还是可以？

在初始化

_spriteBonus=[CCSprite spriteWithFile:@"monstr_1_1.png"];

按计划进行

-(void) openKeyWithSprite:(id) sender withSpriteName:(NSString*)spriteName
{
        CCTexture2D* tex = [[CCTextureCache sharedTextureCache] addImage:spriteName];
        [_spriteBonus setTexture: tex];


}

If you want to create frame animation, use CCAnimate action. For example,

id yourAnimation = [CCAnimation animationWithFrames: arrayOfFrames];
id animateAction = [CCAnimate actionWithDuration: animationDuration 
                                       animation: yourAnimation
                            restoreOriginalFrame: YES];
[yourSprite runAction: animateAction];

if you need to repeat your animation, use CCRepeat of CCRepeatForever action, for example

id resultAction = [CCRepeatForever actionWithAction: animateAction];
[yourSprite runAction: resultAction];

您在此处显示的代码应该没问题，并且不会泄漏任何内存。 setTexture释放旧的纹理参考并保留新的。

但是，假设您没有使用 ARC:[CCSprite spriteWithFile:@"monstr_1_1.png"];在autorelease池中，因此请确保将其添加到父CCNode级（在退出您创建它的任何函数之前），以便将其保留在内存中。
