- (void)connectionDidFinishLoading:(NSURLConnection *)connection

    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; 

    // create the queue to run our ParseOperation 
    self.queue = [[NSOperationQueue alloc] init]; 

    // create an ParseOperation (NSOperation subclass) to parse the RSS feed data so that the UI is not blocked 
    // "ownership of mediaListData has been transferred to the parse operation and should no longer be 
    // referenced in this thread. 
    // 
    ParseOperation *parser = [[ParseOperation alloc] initWithData:listData delegate:self]; 

    [queue addOperation:parser]; // this will start the "ParseOperation" 

    [parser release]; 
    [queue release]; 
    // ownership of mediaListData has been transferred to the parse operation 
    // and should no longer be referenced in this thread

如果錯誤消息來自Xcode靜態分析器，請記住它並不完美，並且可能有誤報。其實，我沒有看到你的代碼有任何問題，但會建議嘗試並用它替換它：

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    self.listFeedConnection = nil; // release our connection 

    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; 

    // create the queue to run our ParseOperation 
    self.queue = [[[NSOperationQueue alloc] init] autorelease]; 

    // create an ParseOperation (NSOperation subclass) to parse the RSS feed data so that the UI is not blocked 
    // "ownership of mediaListData has been transferred to the parse operation and should no longer be 
    // referenced in this thread. 
    // 
    ParseOperation *parser = [[[ParseOperation alloc] initWithData:listData delegate:self] autorelease]; 

    [queue addOperation:parser]; // this will start the "ParseOperation" 

    // ownership of mediaListData has been transferred to the parse operation 
    // and should no longer be referenced in this thread 
    self.listData = nil; 
}
