我是ObC的新手并且有一个我无法解决的问题。可能还有其他问题,但主要问题是:
由于我是新手,我想我做了很多这个错误,但有人可以看看代码并给我一些建议。我会假设我在发布内容时遇到问题。

你过度释放了readDataArray(在没有创建它的方法中称为propArray1)。您创建它并在第二种方法中自动释放它,然后在第一种方法结束时再次释放它(未创建的地方)。

我建议您使用最新XCode附带的Analyze功能。这是一个很好的功能,我总是用来跟踪我是否忘记释放或释放太多。
我还发现你也过度释放propertiesArray
,因为它包含来自[fileString componentsSeparatedByString:]
的结果,根据Cocoa惯例,它将自动释放。
