iOS拓展-APP版本更新

1.获取Apple ID

---

登录iTunes Connect, 在APP信息中,查看应用的Apple ID

2.获取本地应用版本号

---

- (NSString *)getBundleShortVersion {
    // 本地应用信息
    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
    // 本地应用版本号
    NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
    return app_Version;
}

3.请求AppStore中应用信息

---

请求链接:https://itunes.apple.com/lookup?id=(获取的Apple ID)

- (void)getAppStoreVersion {
    NSURL *url = [NSURL URLWithString:@"https://itunes.apple.com/lookup?id=533314804"]; 
    NSURLRequest  *request = [NSURLRequest requestWithURL:url];
    NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        if (data) {
            NSString *JSONStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
            NSLog(@"JSONStr IS %@",JSONStr);
            NSDictionary *JSONDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
            // 正在销售的应用版本号
            self.appStoreVersion = [[JSONDic objectForKey:@"result"] objectForKey:@"version"];
        }
    }];
    [dataTask resume];
}

4.获取当前APP AppStore中的下载链接

---

在AppStore中找到应用,在"获取"中复制链接

5.跳转到AppStore更新应用

---

// 你的应用AppStore下载链接
  NSURL *url = [NSURL URLWithString:@"https://itunes.apple.com/us/app/......."];
// 跳转
 [[UIApplication sharedApplication] openURL:url];
