将字符串泄露给对象时泄漏

我正在接收可追溯至以下方法的NSCFSting泄漏。我解析XML文件，并使用从textForElement获取的字符串并将它们设置为对象中的变量（EventArticleObject）。我知道泄漏不是来自textForElement，因为我没有在另一个解析方法中泄漏，我没有将字符串设置为对象。将字符串泄露给对象时泄漏

我正在填充的数组和字典没有被泄漏，它只是字符串。当我转到堆栈跟踪并单击其中一个泄漏字符串时，显示如下： pic http://img820.imageshack.us/img820/9456/screenshot20110512at939.png ＃2 CFRetain在下面的方法中追溯到setLink，这就是我相信我在做错某事的时候使用对象。

有没有人看到我在这里做错了什么？非常感谢！

TBXML *tbxml;

这里是我的EventArticleObject.m：

@implementation EventArticleObject 

@synthesize link, date, title; 

- (id)initWithTitle:(NSString *)title2 
      date:(NSString *)date2 
      link:(NSString *)link2; 
{ 
    self = [super init]; 
if(!self) 
    return nil; 

    [self setLink:link2]; 
    [self setDate:date2]; 
    [self setTitle:title2]; 

    return self; 
}

我建议你从https://github.com/jayway/CWFoundation抛出赞成CWXMLTranslator'的''TBXML' - 这种方式可以用两条语句和一条小三线DSL替换容易出错的XML解析器代码。 – PeyloW 2011-05-12 13:51:51

@PeyolW感谢您的链接！如果我无法弄清楚这一点，我将继续尝试CWXMLTranslator。 – RyanG 2011-05-12 13:59:23

你还可以发布如何在EventArticleObject中设置属性吗？如果属性被覆盖而不是合成，那么发布这些方法。还有你在哪里发布了eventsDict和datesArray？ – 2011-05-12 14:16:29

验证EventArticleObject类，如果所有的变量被释放正确

你在EventArticleObject的-dealloc方法释放link？
