Switch Account

[khalid usman]

Hi,

I am using google api's in my IOS application. I have added multiple accounts in my IOS device, now I want to get and show all the email id's added on that device. When the user click on specific email, that should be login.

Thanks

SEL finishedSelector = @selector(viewController:finishedWithAuth:error:);
    GTMOAuth2ViewControllerTouch *authViewController =
    [[GTMOAuth2ViewControllerTouch alloc] initWithScope:kGTLAuthScopeDrive
                                               clientID:kClientID
                                           clientSecret:kClientSecret
                                       keychainItemName:userKeyChainName
                                               delegate:self
                                       finishedSelector:finishedSelector];

Here keychainItemName use different value for each user like user1,user2,..........

Retrive user by:

if keychainItemName value is user1

 GTMOAuth2Authentication *auth =[GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:user1
                                                          clientID:kClientID
                                                      clientSecret:kClientSecret];

  GTLServiceDrive *driverService=[[GTLServiceDrive alloc]init];
                 // Have the service object set tickets to fetch consecutive pages
                 // of the feed so we do not need to manually fetch them.
                 driverService.shouldFetchNextPages = YES;
                 // Have the service object set tickets to retry temporary error conditions
                 // automatically.
                 driverService.retryEnabled = YES;
                 [driverService setAuthorizer:auth];
