iphone - ios内存泄漏

Question

我有一个方法可以使用正确的数据设置 NSXMLParser，我很确定会导致内存泄漏。

这是我第一次使用工具来尝试解决内存泄漏并将其归结为有问题的方法..

通过查看仪器内存泄漏测试中的响应调用者值。

我希望你能告诉我内存泄漏在哪里...因为我释放了 myDataArray 和解析器...我只是不确定我哪里出错了..我是否也需要将它们分配为零？

- (void)startTheParsingProcess:(NSData *)parserData
{
    [myDataArray release]; // clears array for next time it is used.
    myDataArray = [[NSMutableArray alloc] init];

    NSXMLParser *parser = [[NSXMLParser alloc] initWithData:parserData]; //parserData passed to NSXMLParser delegate which starts the parsing process 

    [parser setDelegate:self];
    [parser parse]; // starts the event-driven parsing operation.
    [parser release];
}

如有任何帮助，我们将不胜感激。

更新:

我已经对我的应用程序进行了更改，当我在模拟器上运行它时，我没有收到任何内存泄漏错误。

但是，如果我在手机上运行它，请在控制台中获取它...

试着把它放在 .h 中

@property (nonatomic, retain) NSMutableArray *myDataArray

.m

@synthesize myDataArray

in the method...

- (void)startTheParsingProcess:(NSData *)parserData
{
    self.myDataArray = [NSMutableArray arrayWithCapacity:8];

    NSXMLParser *parser = [[NSXMLParser alloc] initWithData:parserData]; //parserData passed to NSXMLParser delegate which starts the parsing process 

    [parser setDelegate:self];
    [parser parse]; // starts the event-driven parsing operation.
    [parser release];
}
