iphone - 在 iPhone 的 Google Auth 2.0 中成功认证后如何继续下一个 API 请求？

Question

在 iPhone 的 google auth2.0 中成功认证后如何进行下一个 api 请求？我得到了带键的返回数据。我需要使用日历 api 和任务 api。

- (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController
  finishedWithAuth:(GTMOAuth2Authentication *)auth
             error:(NSError *)error {


NSString *nextURLString = [NSString stringWithFormat:@"https://www.google.com/calendar/feeds/default/allcalendars/mymail@gmail.com"];
 //i just gave this url for testing. dont know which url is required here.
NSURL *nextURL = [NSURL URLWithString:nextURLString];
NSURLRequest *request = [NSURLRequest requestWithURL:nextURL];
GTMHTTPFetcher *fetcher = [GTMHTTPFetcher fetcherWithRequest:request];
if (error != nil) {
    // Authentication failed
} else {
    // Authentication succeeded

    [fetcher setAuthorizer:auth];
}

}
