当我使用下面的代码，我有错误消息：错误消息：从公共有效的用户设置＆[MC]雷丁[MC]为systemgroup.com.apple.configurationprofiles路径系统组容器是
[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] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles
2017-02-27 01:13:30.090449 RENAULT[210:12313] [MC] Reading from public effective user settings.
的〔自requestFunction]功能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];
我确切的说connectionDidFinishLoading：没有被调用，但是如果我没有使用sendAsynchronousRequest直接启动它，它就可以工作。 那么，为什么我使用sendAsynchronousRequest：函数的事实让我看起来是两个错误消息，以及connectionDidFinishLoading的失误？
预先感谢您。
