Ios 使用块、ARC泄漏sendSynchronousRequest

仪表显示我的代码有漏洞： 泄漏：CFHTTPCookieStorage ->

NSData*resultData=[NSURLConnection sendSynchronousRequest:request returningResponse:&响应错误：&错误]//100.0%

我使用块执行异步下载：

   NSURL *url = [NSURL URLWithString:user.user_photo];
   NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url];
   [NSURLConnection asyncRequestSimple:request success:^(NSData *data) {
        user.user_photo_data=data;
        NSLog(@"Image Downloaded");
        dispatch_async(dispatch_get_main_queue(), ^{
           [tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
        });     

    } failure:^(NSError *error) {
        NSLog(@"Failed downloading");
    }];

使用类别的异步实现：

NSURLConnection+MyExtensions.h

+ (void)asyncRequestSimple:(NSURLRequest *)request success:(void(^)(NSData* data))successBlock_ failure:(void(^)(NSError *error))failureBlock_;

NSURLConnection+MyExtensions.m

+ (void)asyncRequestSimple:(NSURLRequest *)request success:(void(^)(NSData* data))successBlock_ failure:(void(^)(NSError *error))failureBlock_
{

     [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        NSURLResponse *response = nil;
        NSError *error = nil;
        NSData *resultData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];//100% leak

        dispatch_sync(dispatch_get_main_queue(), ^{
            [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
        });

        if (error) {
            failureBlock_(error);
        } else {
            successBlock_(resultData);
        }
    });
}

为什么会漏水

---

已经有一个参数

NSData*data

我更改了名称，泄漏保持不变。我在这里没有看到泄漏。您确定没有将

resultData

泄漏到其他地方吗？可能在您的成功块中？在仪器中，以下行以红色突出显示，标题为100%泄漏：NSData*resultData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]；看到这个问题，可能会给你一个线索。
