这里是InState, tInState are nsmutablearray,被我分配用于负载功能,并在释放时释放。我通过国家抽样调查文件,并说,当我们使用复制件来转让所有权时。我释放了我的所有阵列,为什么它仍然造成问题?

Please help with this. Thanks

Answer 1

第81行,你正在制作一张数字数据,但没有公布,因此正在泄漏。而不是在<代码>addObject上印本电话,将其分配给变量,然后通过addObject,然后予以公布。

id temp = [tData copy];
[tInState addObject:temp];
[temp release];

另外,我假定,<代码>[tData autorelease]实际上是要公布复印件。如果是,就没有必要了。

Answer 2

造成你泄露的原因是,塔瓦塔正在做你告诉它的事情,并归还一份副本。在下一条线路上将自动释放拖拉机,使原来的拖拉机自动化,从而导致释放过多。您将需要将这一行文改为<代码>。 InState AddObject:[tData拷贝] autorelease]]; andmov the autorelease calls on the next line.
