iOS App检测更新

// 1. 获取App的版本

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary]; NSString *currentVersion = [infoDic objectForKey:@"CFBundleShortVersionString"];

// 2. 获取苹果服务器端App 版本号

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];  [manager POST:@"https://itunes.apple.com/lookup?id=Your App Id" parameters:nil success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {             NSArray *array = responseObject[@"results"];             NSDictionary *dict = [array lastObject];             NSString *appStoreVersion = dict[@"version"]; // 苹果服务器端版本号             if (![currentVersion isEqualToString:appStoreVersion]) {

            //3. 如果App的版本号与苹果服务器端App 版本号不一致, 则认为App 非最新版本

                NSLog(@"有新版本可供下载");             }                               } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {          }];

// 备注: 如果App 只在中国上架, 则请求网址:  https://itunes.apple.com/cn/lookup?id=Your App Id
