ios – 错误消息：[MC]从公共有效用户设置读取和[MC] systemgroup.com.apple.configurationprofiles路径的系统组容器是

[NSURLConnection sendAsynchronousrequest:request queue:myQueue completionHandler:^(NSURLResponse *response,NSData *data,NSError *error) {
        NShttpURLResponse *httpResponse = (NShttpURLResponse *) response;
        NSLog(@"response status code: %ld,error status : %@",(long)[httpResponse statusCode],error.description);

        if ((long)[httpResponse statusCode] >= 200 && (long)[httpResponse statusCode]< 400)
            {
               // do stuff
                [self requestFunction]; //Web service
            }
}];

错误消息：

2017-02-27 01:13:30.088641 RENAULT[210:12313] [MC] Sy@R_403_2407@ group container for sy@R_403_2407@group.com.apple.configurationprofiles path is /private/var/containers/Shared/Sy@R_403_2407@Group/sy@R_403_2407@group.com.apple.configurationprofiles
2017-02-27 01:13:30.090449 RENAULT[210:12313] [MC] Reading from public effective user setTings.

[self requestFunction]函数启动一个简单的请求：

NSMutableURLrequest* request = [[NSMutableURLrequest alloc] init];
        NSString *url_String = [bytes StringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
        [request setURL:[NSURL URLWithString:[set_send_order StringByAppendingString: url_String]]];
        [request setCachePolicy:NSURLrequestReloadIgnoringLocalCacheData];
        [request setTimeoutInterval:timeOut];
        [NSURLConnection connectionWithrequest:request delegate:self];

我确切地说没有调用connectionDidFinishLoading：但是如果我在没有sendAsynchronousrequest：的情况下直接启动它,它就可以工作了.
那么为什么我使用sendAsynchronousrequest：函数会让我出现两条错误消息,并且错误地调用了connectionDidFinishLoading？

先感谢您.
