Question

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

这是我第一次使用instriments尝试解决内存泄漏并将其归结为违规方法..

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...因为我发布了myDataArray和解析器...我只是不确定我哪里出错了...我还需要分配它们吗？< / p>

- (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];
}

任何帮助将不胜感激。

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，请在控制台中进行操作...

尝试将其放入.h

@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];
}
