无法在ios 7设备上的视图控制器上隐藏状态栏.

已经尝试通过plist文件和Appcontroller.mm设置,但我仍然没有隐藏状态栏

[[UIApplication sharedApplication] setStatusBarHidden:YES];//Doesn't help

我正在使用AFNetworking进行一些GET查询.但我的函数总是返回nil值.哪里错了？

+ (NSString *)getRequestFromUrl:(NSString *)requestUrl {
    NSString * completeRequestUrl = [NSString stringWithFormat:@"%@%@", BASE_URL, requestUrl];
    __block NSString * results;
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager GET:completeRequestUrl parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        results = [NSString stringWithFormat:@"%@", responseObject];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        results = [NSString stringWithFormat:@"Error"];
    }];
    NSLog(@"%@", results);
    return results;
}

谢谢!阿尔乔姆.
