Register your application to launch from a custom URL scheme, and use that with the path /success as your callback URL. The callback for the custom URL scheme should send a notification, which will complete the OAuth transaction.
Here's how to create a client and authenticate:
AFOAuth1Client *twitterClient = [[[AFOAuth1Client alloc] initWithBaseURL:[NSURL URLWithString:@"https://twitter.com/oauth/"] key:@"..." secret:@"..."] autorelease];
// Your application will be sent to the background until the user authenticates, and then the app will be brought back using the callback URL
[twitterClient authorizeUsingOAuthWithRequestTokenPath:@"/request_token" userAuthorizationPath:@"/authorize" callbackURL:[NSURL URLWithString:@"x-com-YOUR-APP-SCHEME://success"] accessTokenPath:@"/access_token" success:^(AFOAuth1Token *accessToken) {
NSLog(@"Success: %@", accessToken);
} failure:^(NSError *error) {
NSLog(@"Error: %@", error);
}];Here's how to respond to the custom URL scheme on iOS:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
NSNotification *notification = [NSNotification notificationWithName:kAFApplicationLaunchedWithURLNotification object:nil userInfo:@{kAFApplicationLaunchOptionsURLKey: url}];
[[NSNotificationCenter defaultCenter] postNotification:notification];
return YES;
