コールバックURLを指定する必要があります。デフォルトでは "oob"で、検証者コードを与えます。独自のWebビューを表示し、Webビューの代理人によって検証コードを監視する方が良いでしょう。あなたのやり方は次のとおりです。
YOSSession *yahooSession; //instance variable
- (IBAction)yahooButtonAction:(UIButton *)sender {
yahooSession = [YOSSession sessionWithConsumerKey:YAHOO_CONSUMER_KEY
andConsumerSecret:YAHOO_CONSUMER_SECRET
andApplicationId:YAHOO_APP_ID];
// try to resume a user session if one exists
BOOL hasSession = [yahooSession resumeSession];
if(hasSession == FALSE) {
[self fetchSession];
}else{
[self sendRequests];
}
}
-(void)fetchSession{
// create a new YOSAuthRequest used to fetch OAuth tokens.
YOSAuthRequest *tokenAuthRequest = [YOSAuthRequest requestWithSession:yahooSession];
// fetch a new request token from oauth.
YOSRequestToken *newRequestToken = [tokenAuthRequest fetchRequestTokenWithCallbackUrl:@"http://localhost"];
// if it looks like we have a valid request token
if(newRequestToken && newRequestToken.key && newRequestToken.secret) {
// store the request token for later use
[yahooSession setRequestToken:newRequestToken];
[yahooSession saveSession];
// create an authorization URL for the request token
NSURL *authorizationUrl = [tokenAuthRequest authUrlForRequestToken:yahooSession.requestToken];
[self presentWebViewForYahooWithAuthURL:authorizationUrl];
//present it in webview
} else {
// NSLog(@"error fetching request token. check your consumer key and secret.");
}
}
-(void) presentWebViewForYahooWithAuthURL:(NSURL *)url{
_yahooWebView = [[UIWebView alloc] initWithFrame:self.view.frame];
_yahooWebView.delegate=self; //so that we can observe the url for verifier
[_yahooWebView loadRequest:[NSURLRequest requestWithURL:url]];
[self.view addSubview:_yahooWebView];
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
NSString *requestString = request.URL.absoluteString;
if ([requestString rangeOfString:@"http://localhost"].length>0) {
NSRange verifierRange = [requestString rangeOfString:@"oauth_verifier="];
