 ////////////////////////////////////////////////////////////////版本更新开始    //判断是不是WiFi，如果是WiFi则提醒用户更新    [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {        if ([AFStringFromNetworkReachabilityStatus(status) isEqualToString:@"Reachable via WiFi"]) [self update];    }];    [[AFNetworkReachabilityManager sharedManager] startMonitoring];    /////////////////////////////////////////////////////////////////版本更新结速

二.把更新的代码重构到一个方法里

- (void)update {    NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];    NSString *oldVersion = infoDict[@"CFBundleShortVersionString"];    NSString *url = [[NSString alloc] initWithFormat:@"http://itunes.apple.com/lookup?id=%@", @"你的appID"];    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];    //申明返回的结果是json类型    manager.responseSerializer = [AFJSONResponseSerializer serializer];    //申明请求的数据是json类型    manager.requestSerializer = [AFJSONRequestSerializer serializer];    //如果报接受类型不一致请替换一致text/html或别的  //  manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/javascript", nil nil];   // manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/javascript"];    [manager POST:url parameters:nil progress:^(NSProgress * _Nonnull uploadProgress) {    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {        NSNumber *number = responseObject[@"resultCount"];        if (number.intValue == 1) {            NSString *newVersion = responseObject[@"results"][0][@"version"];            NSString *updateMsg = responseObject[@"results"][0][@"releaseNotes"];            if (![newVersion isEqualToString:oldVersion]) {                //图2样式                //UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"有新版本可供更新" message:updateMsg preferredStyle:UIAlertControllerStyleAlert];//图1样式                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"有新版本可供更新" message:nil preferredStyle:UIAlertControllerStyleAlert];                UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"更新" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"URLString"]];                }];                UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:nil];                [alertController addAction:cancleAction];                [alertController addAction:okAction];                [self presentViewController:alertController animated:YES completion:nil];            }        }    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {        NSLog(@"%@", error);    }];  }

上面的URLString是你的应用在app store的链接:打开iTunes,搜索到你的应用后右单击应用的logo,如下图,选择拷贝链接.
上面的appID就是链接中id后面的数字.
