I am making an application to integrate gmail to my app. I am able to login to gmail by gadata-objective c-client-1.11.0.a. I am giving the code
-(IBAction)googlelogin
{
NSString *scope = #"https://www.googleapis.com/auth/plus.me"; // scope for Google+ API
GTMOAuth2ViewControllerTouch *viewController = [[[GTMOAuth2ViewControllerTouch alloc] initWithScope:scope clientID:kMyClientID clientSecret:kMyClientSecret keychainItemName:nil delegate:self finishedSelector:#selector(viewController:finishedWithAuth:error:)] autorelease];
NSString *html = #"<html><body><div align=center>Loading sign-in page...</div></body></html>";
[viewController setInitialHTMLString:html];
[self presentModalViewController:viewController animated:NO];
}
now i want to redirect back to my app after google login to get the contacts of gmail. Help me how to generate taken and return back to my app after login
thanks
you should implement the method
- (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController
finishedWithAuth:(GTMOAuth2Authentication *)auth
error:(NSError *)error {
if (error != nil) {
// Authentication failed
} else {
// Authentication succeeded
// here you should push your the root view controller of your app.
}
}

I have integrated Facebook login in my app and therfore user can login with both my app account and also Facebook and do corresponding actions.For Facebook integration I have added Facebook SDK.Now when Logout button is clicked in my app it has to clear all the credentials of Facebook Account.I have gone for :
-(IBAction)btnlogOutClicked:(id)sender
{
[appDelegate fbDidlogout];
}
-(void)fbDidlogout
{
FBSession* session = [FBSession activeSession];
[session closeAndClearTokenInformation];
[session close];
[FBSession setActiveSession:nil];
}
But when I again click on button I m redirected directly to my account without going to Facebook Login page.
How can I logout of Facebook?
Using new Facebook SDK login kit just write below line and thats it..
[[FBSDKLoginManager new] logOut];
If using swift, make sure to have the necessary imports
import FBSDKLoginKit
func logout() {
FBSDKLoginManager().logOut()
}
For logout you should try this
you can add the Logout button on Navigation Controller (Top Right Corner) in viewDidLoad method
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithTitle:#"Logout"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(logoutButtonWasPressed:)];
and the action method for above added button is
-(void)logoutButtonWasPressed:(id)sender {
[FBSession.activeSession closeAndClearTokenInformation];
}
Hope this will help you!
Reference
Edit:
As you asked why its not asking for UserName and Password,So the reason is :
When we integrate Facebook SDK in our app and try to login, it automatically check two places (to make sure we have already logged-in Facebook or not)
First of all It checks whether we have already logged-in into Facebook Native app which is installed on this device.
then It checks whether we have saved our FaceBook UserName and Password in Device Settings.
If both places we haven't logged-in then It will ask UserName and Password in application
you can check Facebook account setup in Device Settings as shown in below screen shot,
Press Home Button --> Settings -->Facebook
FBSDK is doing logout like this:
[FBSession.activeSession closeAndClearTokenInformation];
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logOut];
If using swift 3 or 4:
var loginManager = LoginManager()
Paste this code when some action is need to be done for logging out
loginManager.logOut()
In your postButtonClicked write following if else :
-(void)postButtonClicked
{
_session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain];
[_session resume];
posting = YES;
showSlideShow = 1;
if (_facebookName != nil)
{
[self logoutButtonClicked];
}
if (![_session isConnected])
{
self.loginDialog = nil;
_loginDialog = [[FBLoginDialog alloc] init];
[_loginDialog show];
}
else {
self.loginDialog = nil;
_loginDialog = [[FBLoginDialog alloc] init];
[_loginDialog show];
}
}
I have this code in my Application:
if (self.uiSwtichState == TRUE)
{
if ([CLLocationManager locationServicesEnabled])
{
[self.textString stringByAppendingString:[[[SMSLocationModel alloc] init] getLocation]];
}
}
MFMessageComposeViewController *sms = [[MFMessageComposeViewController alloc] init];
sms.messageComposeDelegate = self;
sms.body = self.textString;
sms.recipients = self.arrayOfNumbers;
[self presentModalViewController:sms animated:YES];
this code is into a method called "send".
As you can imagine, the method getLocation get the current user location and, the first time the Application run, a UIAlertView appear on the screen asking the user if he want to allow the application to get his location.
The problem is that when this UIAlertView appear, she is immediately replaced by the sms Vie Controller (MFMessageComposeViewController) and in this way the user doesn't have enough time for answer YES or NO in the UIAlertView.
There is a way for wait that the user press a button in the UIAlertView and THEN present the ModalViewController?
Thanks!
you could use the CLLocationManagers delegate method to wait until the authorization state changes. Save the sms viewController to an instance variable if you are not authorized to use location services. then ask the location manager to authorize you. If the authorization state changes present that view controller.
// somewhere else
self.locationManager.delegate = self;
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
NSLog(#"New Authorization State: %d", status);
if (self.viewControllerToPresentAfterLocationDidChange) {
if (status == kCLAuthorizationStatusAuthorized) {
// set location of viewController
[self presentViewController:self.viewControllerToPresentAfterLocationDidChange animated:YES completion:NULL];
}
else {
// user did not authorize you to use location services
}
self.viewControllerToPresentAfterLocationDidChange = nil;
}
}
- (IBAction)buttonPressed:(id)sender {
UIViewController *vc = [[UIViewController alloc] init];
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorized) {
// authorized already, no alert will appear.
// set location of vc
[self presentViewController:vc animated:YES completion:NULL];
}
else if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined){
self.viewControllerToPresentAfterLocationDidChange = vc;
// access location so alert will show
}
else {
// not authorized or restricted.
}
}
Maybe you can use this delegate:
- (void)didPresentAlertView:(UIAlertView *)alertView{
}
For example, initializing a boolean which can prevent of presenting this modal view controller. Then if dismissed change the boolean to allow presenting this view controller.
Yes, you can implement the AlertViewDelegate.
See UIAlertViewDelegate Documentation for further information.
Then you can use the alertView:clickedButtonAtIndex: method and present your MessageComposer when the user has clicked the alert view.
I am using xcode 4.2 and i am developing an iphone APP , part of this app is sending SMSs
here is the code that I typed:
-(IBAction)SMSbutton{
MFMessageComposeViewController *sms = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText]) {
sms.body= [NSString stringWithFormat: #"text"];
sms.messageComposeDelegate = self;
[self presentModalViewController:sms animated:YES];
}
I can open the SMS application and send SMS but the problem is whether I click on the "cancel" or the "send" button the message application does not go away . how to do that ?
thanks
Set your calling class to be a delegate of the message composer, then catch the cancel and send events to dismiss the modal view controller as needed.
Set your header file to adhere to the MFMessageComposeViewControllerDelegate, and when you initialize the composer, set the message delegate to self:
MFMessageComposeViewController *george = [MFMessageComposeViewController alloc] init];
george.messageComposeDelegate = self;
Then implement the delegate method...easiest way is:
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissModalViewControllerAnimated:YES];
}
...but you can catch and deal with errors and events as necessary.
Implement messageComposeViewController:didFinishWithResult: in your delegate"
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
if(result == MessageComposeResultCancelled) {
//Message cancelled
} else if(result == MessageComposeResultSent) {
//Message sent
}
[self dismissModalViewControllerAnimated:YES];
}
Have you tried dismissViewControllerAnimated:completion: or dismissModalViewControllerAnimated:?
[self dismissModalViewControllerAnimated: YES];
I am developing a iPhone application which sends tweets to twitter. For this I am using SA_OAuthTwitterEngine + MGTwitterEngine classes.
I register applicaiton to www.twitter.com/apps and pass Consumer key and Consumer secret to controller my code is this.
if(!_engine){
_engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate:self];
_engine.consumerKey = slPcFUjUh5y1hex0zvEhPg;
_engine.consumerSecret = u6ydovMdP9yeiVqDukVhIzZPgJR9XDPUwfxymzNs;
}
UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine:_engine delegate:self];
if (controller){
[self presentModalViewController: controller animated: YES];
intTwitterFlag = 1;
}
Previously on twitter.com/apps I select Application type = client and my application will generate PIN and accessToken. But when i change my Application type = Browser it cannot generate PIN and accessToken.
Previously when application type is client i am giving user name and password and then control return to my application from the webview but now after entering user name and password it cannot dismissModalViewController but showing Select and Copy the PIN.
Thank you for your time and any help you can give me!
Here it is:just replace the method in SA_OAuthTwitterController.m:
- (void) webViewDidFinishLoad: (UIWebView *) webView {
_loading = NO;
//[self performInjection];
if (_firstLoad) {
[_webView performSelector: #selector(stringByEvaluatingJavaScriptFromString:) withObject: #"window.scrollBy(0,200)" afterDelay: 0];
_firstLoad = NO;
} else {
/*
NSString *authPin = [self locateAuthPinInWebView: webView];
NSLog(#"authPin: %#", authPin);
if (authPin.length) {
[self gotPin: authPin];
return;
}
NSString *formCount = [webView stringByEvaluatingJavaScriptFromString: #"document.forms.length"];
if ([formCount isEqualToString: #"0"]) {
[self showPinCopyPrompt];
}*/
//*****************************************************
// This is to bypass the pin requirement
// in case the call back URL is set in Twitter settings
//*****************************************************
[_engine requestAccessToken];
if ([_delegate respondsToSelector: #selector(OAuthTwitterController:authenticatedWithUsername:)])
{
[_delegate OAuthTwitterController: self authenticatedWithUsername: _engine.username];
}
[self performSelector: #selector(dismissModalViewControllerAnimated:) withObject: (id) kCFBooleanTrue afterDelay: 1.0];
//[self dismissModalViewControllerAnimated:YES];
}
[UIView beginAnimations: nil context: nil];
_blockerView.alpha = 0.0;
[UIView commitAnimations];
if ([_webView isLoading]) {
_webView.alpha = 0.0;
} else {
_webView.alpha = 1.0;
}
}
I too faced the same issue, and i just removed callback url from the twitter app settings. For my surprise login proceeds without any issue.
The replacement for this method
(void) webViewDidFinishLoad: (UIWebView *) webView
in the class SA_OAuthTwitterController.m works well.
Its better to use xAuth route for mobile apps
http://dev.twitter.com/pages/xauth
check XAuthTwitterEngine which implements xauth for the MGTwitterEngine
Does anyone know how I would include a facbeook "like button" in an iphone app. I tried calling the iframe inside of a UIWebView but that doesn't work.
Check out this nice bit of code:
http://angelolloqui.blogspot.com/2010/11/facebook-like-button-on-ios.html
Add the FBLikeButton class to your view:
FBLikeButton *likeButton = [[FBLikeButton alloc] initWithFrame:CGRectMake(0, 372, 320, 44)
andUrl:#"http://www.facebook.com/pages/De-Zilk/108209735867960"];
Thanks a lot Angel García Olloqui
EDIT: Nice to add... For bonus points:
If you use above method the webpage is not well formatted for an iPhone. What you can do is run some JavaScript code to remove all the disturbing divs. Use this (long sentence):
[_webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:#"javascript:document.getElementsByClassName('uiButton')[2].style.visibility='hidden';var child1 = document.getElementById('standard_status');var parent1 = document.getElementById('login_form');parent1.removeChild(child1);var child2 = document.getElementById('pageheader');var parent2 = document.getElementById('booklet');parent2.removeChild(child2);document.getElementById('loginform').style.width = '200px';var child3 = document.getElementById('reg_btn_link');var parent3 = document.getElementsByClassName('register_link')[0];parent3.removeChild(child3);var child4 = document.getElementById('signup_area');var parent4 = document.getElementById('login_form');parent4.removeChild(child4);var child5 = document.getElementsByClassName('mbm')[0];var parent5 = document.getElementById('loginform');parent5.removeChild(child5);var child6 = document.getElementsByClassName('reset_password form_row')[0];var parent6 = document.getElementById('loginform');parent6.removeChild(child6);var child7 = document.getElementsByClassName('persistent')[0];var parent7 = document.getElementById('loginform');parent7.removeChild(child7);"]];
You can place it in the delegate method webViewDidFinishLoad from the FBDialog Facebook class.
Fb like Widget can be embedded in our application. You just have to add a webView and get the Fb Like Widget html code/URL here.
in ViewController.h where you want to add fb like button:
#import <UIKit/UIKit.h>
#interface TestViewController : UIViewController <UIWebViewDelegate>
#property (strong, nonatomic) UIWebView * fbLikeWebView;
-(void)embedFBLikeButton;
#end
in TestViewController.m
#import "AboutUsViewController.h"
#implementation AboutUsViewController
#synthesize fbLikeWebView = _fbLikeWebView;
- (void)viewDidLoad
{
[super viewDidLoad];
//Add this code for FbLike Webview
self.fbLikeWebView = [[UIWebView alloc] initWithFrame: CGRectMake(100.0, 50.0, 55.0, 70.0)];
_fbLikeWebView.opaque = NO;
_fbLikeWebView.backgroundColor = [UIColor clearColor];
_fbLikeWebView.delegate = self;
[self.view addSubview:_fbLikeWebView];
for (UIScrollView *subview in _fbLikeWebView.subviews)
{
if ([subview isKindOfClass:[UIScrollView class]]) {
subview.scrollEnabled = NO;
subview.bounces = NO;
}
}
}
then in ViewWillAppear method call the enbeddFBLikeButton Method to add the fbLike button wigdet on web view:
-(void)viewWillAppear:(BOOL)animated
{
[self embedFBLikeButton];
[_fbLikeWebView reload];
}
-(void)embedFBLikeButton
{
NSString *facebookUrl = //here paste the url you get from fb developer link above;
[self.fbLikeWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:facebookUrl]]];
}
You conform to UIWebViewDelegate now its turn to defining th edelegate method here:
#pragma mark - WebView Delgate Methods
- (BOOL)webView:(UIWebView *)webview shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
if ([request.URL.lastPathComponent isEqualToString:#"login.php"])
{
[self login];
return NO;
}
return YES;
}
-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
[_fbLikeWebView stopLoading];
}
This method for login the user to facebook Account:
- (void)login
{
[FBSession setActiveSession: [[FBSession alloc] initWithPermissions:#[#"publish_actions", #"publish_stream", #"user_photos"]]];
[[FBSession activeSession] openWithBehavior: FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
// call the legacy session delegate
//Now the session is open do corresponding UI changes
if (session.isOpen) {
FBRequest *me = [FBRequest requestForMe];
[me startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *my,
NSError *error) {
if (!my) {
NSLog(#"Facebook error:\n%#", error.description);
[[[UIAlertView alloc] initWithTitle: #"Error"
message: #"Facebook Login error."
delegate: self
cancelButtonTitle: #"Ok"
otherButtonTitles: nil, nil] show];
return;
}
}];
[_fbLikeWebView reload];
[[[UIAlertView alloc] initWithTitle: #""
message: #"Successfully Login. Please click on like button"
delegate: self
cancelButtonTitle: #"Ok"
otherButtonTitles: nil, nil] show];
}
break;
case FBSessionStateClosedLoginFailed:
{
[_fbLikeWebView reload];
}
break;
default:
break; // so we do nothing in response to those state transitions
}
}];
}
It is an old question, but we just got the answer
By using fb sdk now we can simply add the like button
FBLikeControl *likeButton = [[FBLikeControl alloc] init];
like.objectID = #"http://ihackthati.wordpress.com/photo1/";
[self addSubview:like];
https://developers.facebook.com/docs/ios/like-button/
Several of the solutions above (e.g. #floorjiann, #fabiobeta, #Stephen-Darlington, #scott) assume that the iPhone application is also a Facebook application (with its own id).
However if your iPhone application just has a fan page, this is not the case.
You can include it in a UIWebView, just make sure it's inside <html><body>. The problem is that once the user clicks the button, the UIWebView may redirect to a log-in form, so you would have to make it large enough to fit that thing.
Have fun creating a design that presents the button in a sensible fashion.
maybe this is helpful

Facebook have recently updated their iPhone Facebook Connect framework to work with the Graph API. This is the API that you need to "Like" objects on Facebook.
Here you go - w the source code...enjoy -and please leave a comment if its useful.
http://nowbranded.com/blog/adding-a-facebook-like-button-to-an-iphone-application/
First check your authentication on Facebook, then use url code instead of iFrame like this:
NSURL *url = [NSURL URLWithString:#"http://www.facebook.com/plugins/like.php?href=https%3A%2F%2Fwww.facebook.com%2FRemtechConfessionChambers&width=200&height=80&colorscheme=light&layout=standard&action=like&show_faces=true&send=false"];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[webViewFb loadRequest:req];
You can use the open source SOOMLA Profile plugin:
https://github.com/soomla/ios-profile
There are code examples there for lots of Facebook related actions (login, like, share status, upload image, get contacts, invite, etc.). See:
https://github.com/soomla/ios-profile/blob/master/SoomlaiOSProfileExample/SoomlaiOSProfileExample/ViewController.m
I this moment in time you can't. The mobile APIs are not exposing this capability.
You can use some workaround consisting in embedding the html way of doing it in your app.
Some details on the workaround here: http://petersteinberger.com/2010/06/add-facebook-like-button-with-facebook-connect-iphone-sdk/
