Question

我的（Unity）应用程序抱怨我的iPod没有网络连接，而设备具有完整的Wi-Fi连接（所有其他应用程序，包括Safari）都证明了这一点。

这不仅仅是一个API点 - 所有这些（Facebook，StoreKit等）声称网络不可用。

此消息会定期从我的应用程序发送到控制台：

<Error>: Could not successfully update network info during initialization.

可能（我认为）来自 CoreTelephony 。

知道造成这种情况的原因是什么？我在调试和adhoc构建中得到它。我没有在设备上激活任何限制（来自设置）。

该设备是iOS 6，基本sdk是iOS 5.

Answer 1

＆＃34;无法在初始化期间成功更新网络信息。＆＃34;每次在没有SIM卡的设备（iPod touch或没有3G的iPad）中初始化CTTelephonyNetworkInfo时都会显示日志。

如果它非常烦人，您只需初始化一次并对该实例进行网络检查。

Answer 2

检查开发者工具，检查您是否意外开启了100％互联网丢失。它应该在调试菜单中。

Answer 3

我尝试在appDelegate.m中的模拟器和CTTelephonyNetworkInfo初始化中设置位置但不起作用。我通过定义一个新类APIAgent.m来修复它：

+ (APIAgent *)manager {
    static APIAgent *_manager = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _manager = [[APIAgent alloc] initWithBaseURL:[NSURL URLWithString:API_URL]];
        _manager.responseSerializer = [AFJSONResponseSerializer serializer];
        NSMutableIndexSet* codes = [NSMutableIndexSet indexSetWithIndexesInRange: NSMakeRange(200, 100)];
        [codes addIndex: 400];
        [codes addIndex: 401];
        [codes addIndex: 404];
        [codes addIndex: 409];
        [codes addIndex: 500];
        _manager.responseSerializer.acceptableStatusCodes = codes;
    });

    return _manager;
}

- (id)initWithBaseURL:(NSURL *)url {
    self = [super initWithBaseURL:url];
    if (!self) {
        return nil;
    }

    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];

    [self setHeaders];

    return self;
}

                     complete:(void (^)(NSURLSessionDataTask *task, id responseObject, NSError *error))complete {
    return [self GET:URLString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        if (complete) {
            complete(task, responseObject, nil);
        }
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        if (complete) {
            complete(task, nil, error);
        }
    }];
}

- (NSURLSessionDataTask *)POST:(NSString *)URLString parameters:(id)parameters complete:(void (^)(NSURLSessionDataTask *task, id responseObject, NSError *error))complete {
    return [self POST:URLString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        if (complete) {
            complete(task, responseObject, nil);

    } failure:^(NSURLSessionDataTask *task, NSError *error) {

    } else {

        }

}

- (void)setHeaders {
    NSString *time = [NSString stringWithFormat:@"%f", [[[NSDate alloc] init] timeIntervalSince1970]];
    AFHTTPRequestSerializer * serializer = self.requestSerializer;
    [serializer setValue:time forHTTPHeaderField:@"X-API-TIME"];
    [serializer setValue:[UIDevice currentDevice].identifierForVendor.UUIDString forHTTPHeaderField:@"X-UUID"];

    [serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

    NSString *preferredLang = [NSLocale preferredLanguages].firstObject;

    [serializer setValue:preferredLang forHTTPHeaderField:@"X-USER-LANGUAGE"];
}

为什么这个iOS应用程序无法访问网络？
