大家帮忙看看这里哪里有泄露

- (void)viewDidLoad {
    NSMutableArray *myrssList = [[NSMutableArray alloc] initWithCapacity:1];
    self.rssList = myrssList;
    [myrssList release];
    
    NSString *paths = [[NSBundle mainBundle] resourcePath];
    NSString *xmlFile = [paths stringByAppendingPathComponent:@"rssfeeds.xml"];
    NSURL *xmlURL = [NSURL fileURLWithPath:xmlFile isDirectory:NO];
    
    NSXMLParser *toutiaoParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];
    [toutiaoParser setDelegate:self];
    [toutiaoParser parse];
    [super viewDidLoad];
}

instruments老是显示NSXMLParser *toutiaoParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];这一行有泄露，怎么回事啊。
在下面我已经清理了解析器，所以如果在这里release掉toutiaoParser，会报双释放的错误
大家帮忙看看哪里有问题

答：

随便试了个方法居然没有泄露了
我用了一个NSData的变量做了个过渡
- (void)viewDidLoad {
    NSMutableArray *myrssList = [[NSMutableArray alloc] initWithCapacity:1];
    self.rssList = myrssList;
    [myrssList release];
    
    NSString *paths = [[NSBundle mainBundle] resourcePath];
    NSString *xmlFile = [paths stringByAppendingPathComponent:@"rssfeeds.xml"];
    NSURL *xmlURL = [NSURL fileURLWithPath:xmlFile isDirectory:NO];
//  NSXMLParser *toutiaoParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];  这个是先前有问题的行

    NSData *xmlData = [NSData dataWithContentsOfURL:xmlURL];     //用一个NSData变量过渡
    NSXMLParser *toutiaoParser = [[NSXMLParser alloc] initWithData:xmlData];   //initWithContentsOfURL改成initWithData

    [toutiaoParser setDelegate:self];
    [toutiaoParser parse];

    [super viewDidLoad];
}

下面的解析器清理
//清理解析器
- (void)parserDidEndDocument:(NSXMLParser *)parser {
    [parser release];
}

我想应该是initWithContentsOfURL有什么问题，还是学术才浅啊，都不知道这里有什么不对的.....
