problem with intergating facebook session - iphone

I am using Facebook in my music application where user post comment on wall paper after listening the songs . So problem arises that user have to login again for next song. so please provide me code for session retains when he clicked on the tab where it written "keep me login".
Thanks

I have a file called FacebookHelper.m, here is the code there:
- (id)init {
if (self = [super init]) {
session_ = [[FBSession sessionForApplication:kAPIKey secret:kApplicationSecret delegate:self] retain];
[session_ resume];
}
return self;
}
If you want to control the login dialog yourself, here is the code:
- (void)loginByShowingDialog {
self.isDialogShown = YES;
FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:self.session] autorelease];
dialog.delegate = self;
[dialog show];
}
For your cases, I think you only need to get the session back and resume it.

Logout of Facebook in app using Facebook ios SDK

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];
}
}

How to accept an invitation in Game Center

I'm trying to implement invitations with Game Center and there's one thing that i don't understand. Ok, i've sent an invitation from one device to another. Then i have an UIAlertView on receiver which asks me i would like to accept or decline the invitation. when i accept it it is handled like this:
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite)
{
// Insert application-specific code here to clean up any games in progress.
if (acceptedInvite)
{
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
mmvc.matchmakerDelegate = self;
[presentingViewController presentModalViewController:mmvc animated:YES];
}
else if (playersToInvite)
{
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = 2;
request.maxPlayers = 4;
request.playersToInvite = playersToInvite;
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;
[presentingViewController presentModalViewController:mmvc animated:YES];
}
};
Well, that's great, but what next? the sender device is obviously waiting for some standard type of response, cause it also shows an alert telling me that there's some invitations not answered yet if i tap "Play now".
So how do i accept an invitation? What kind of data (and how) should i send back? And what exactly should i do on the receiver's side? Should game start instantly after tapping "Accept" or i should dismiss the AlertView first and then tap "Play now"?
Ray Wenderlich's tutorial says that i should choose second way but when dismiss the alert and tap "Play now" it turns out the sender device is still waiting for response and is not aware that i have already accepted the invitation. if i tap "Play now" at this moment then, as i said above, it shows an alert which says that the application is waiting for the response. So if you've ever done that then please explain me what should i do. Thanks!
I register for invites as soon as the game is loaded and call the
delegate when an invite is received
So inviteReceived calls the match maker for dismissing the game
center controller and creating the match
And finally, when the match is being found, the method
connectionStatusChanged takes care of presenting all the game's
views and players and stuff
Here is the code:
I register for invites as soon as the game is loaded and call the delegate when an invite is received:
- (void)registerInvites {
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
self.pendingInvite = acceptedInvite;
self.pendingPlayersToInvite = playersToInvite;
[delegate inviteReceived];
};
}
So inviteReceived calls the match maker for dismissing the game center controller and creating the match:
- (void)inviteReceived {
[[GCMultiplayerHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController:(UIViewController*)[self.superview nextResponder] delegate:self];
}
- (void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers viewController:(UIViewController *)viewController delegate:(id<GCMultiplayerHelperDelegate>)theDelegate {
if (!gameCenterAvailable) return;
matchStarted = NO;
self.match = nil;
self.presentingViewController = viewController;
delegate = theDelegate;
[presentingViewController dismissModalViewControllerAnimated:YES];
GKMatchmakerViewController *mmvc;
if (pendingInvite != nil) {
mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:pendingInvite] autorelease];
} else {
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = minPlayers;
request.maxPlayers = maxPlayers;
request.playersToInvite = pendingPlayersToInvite;
mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
}
mmvc.matchmakerDelegate = self;
[presentingViewController presentModalViewController:mmvc animated:YES];
self.pendingInvite = nil;
self.pendingPlayersToInvite = nil;
}
And finally, when the match is been found, the method connectionStatusChanged takes care of presenting all the game's views, players and starting the match:
- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)theMatch
{
self.match = theMatch;
match.delegate = self;
if (!matchStarted && match.expectedPlayerCount == 0) {
NSLog(#"Ready to start match! - didFindMatch");
[presentingViewController dismissModalViewControllerAnimated:YES];
[self.delegate connectionStatusChanged:CONNECTIONSUCCESS];
}
}
I've successfully implemented an online game center match following Ray's tutorials. The answer to you question is: You don't have to send anything to the inviting device. When you call the line:GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];, the matchMakerVController handles the connection . However, you should write an invitation handler ASAP, preferably in the authentication changed method. See mine:
-(void) authenticationChanged {
if ([GKLocalPlayer localPlayer].isAuthenticated && !userAuthenticated) {
NSLog(#"Authentication changed: player authenticated.");
userAuthenticated = TRUE;
[self sendUnsentScores];
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite){
NSLog(#"Invite");
if([AppDelegate mainMenuController].presentedViewController!=nil) {
[[AppDelegate mainMenuController] dismissViewControllerAnimated:NO completion:^{
}];
} // if we're not on the main menu, or another game is going on.
// this would be easier to do if you were using a navigation controller
// where you'd just push the multiplayer menu etc.
self.pendingInvite = acceptedInvite;
self.pendingPlayersToInvite = playersToInvite;
[[AppDelegate mainMenuController] presentViewController:[AppDelegate mainMenuController].multiGameMenu animated:NO completion:^{ // push the multiplayer menu
[[AppDelegate mainMenuController].multiGameMenu duel:nil];
}];
};
}
and here is the duel method if you're interested. Very messy code but deal with it :)
- (IBAction)duel:(id)sender {
NSLog(#"duel");
if (presentingMenu.multiGameController==nil || presentingMenu.multiGame.gameInProgress==NO) {
presentingMenu.multiGame=nil;
presentingMenu.multiGameController=nil;
MultiViewController *mvc = [[MultiViewController alloc] init]; //create game VC
presentingMenu.multiGameController = mvc; //presenting menu is just the main menu VC
// it holds this menu, and the game
// objects.
}
if (presentingMenu.multiGame == nil) {
presentingMenu.multiGame = [[MultiGame alloc] // similarly create the game object
initWithViewController:presentingMenu.multiGameController];
//they both have pointers to each other (A loose, bad MVC).
presentingMenu.multiGameController.game = presentingMenu.multiGame;
[presentingMenu.multiGame startGame];
}
if (presentingMenu.multiGameController.gameState==0) { //new game
presentingMenu.multiGameController.game = presentingMenu.multiGame;
[[GCHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController:self delegate:presentingMenu.multiGame]; // the GC magic happens here - it know about the invite.
} else {
[self presentViewController:presentingMenu.multiGameController animated:YES completion:^{
}];
}
}
inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) is deprecated now. See the new way to register for invite notifications.

Adding the Facebook Like Button in an iPhone App

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 GarcĂ­a 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
http://www.raywenderlich.com/1626/how-to-post-to-a-users-wall-upload-photos-and-add-a-like-button-from-your-iphone-app
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/

When is Facebook Connect supposed to call its delegate methods?

The Facebook connect code is eluding me a bit.
I have no problem doing a login, and a wall post, however, I simply can not
figure out how the delegate methods for the FBDialog andFBStreamDialog is supposed to work.
- (void)postToWall {
FBStreamDialog *dialog = [[[FBStreamDialog alloc] init] autorelease];
dialog.delegate = self;
dialog.userMessagePrompt = #"Enter your message:";
dialog.attachment = [NSString stringWithFormat:#"JSONpost code"];
[dialog show];
}
I adhere to these protocols in my controller:
<FBDialogDelegate, FBSessionDelegate, FBRequestDelegate>
I then implement the two methods:
- (void) dialogDidCancel:(FBDialog *)dialog {
NSLog(#"Failed");
}
- (void) dialogDidSucceed:(FBDialog *)dialog {
NSLog(#"Success");
}
After I tap "publish" and the postToWall methods is done executing the Facebook "pop up" in the UI is empty, except a small "X" in the top right corner and a "F" (facebook logo) in the top left corner.
The UI will stay there until I tap the "X", this results in the dialogDidCancel delegate method being called. The post data is showing up on the Facebook page, everything seems to work.
Why is thedialogDidSucceedmethod never called? I need this to release my facebook controller and restore the UI back to where the user was before "starting" FB Connect.
Thank You:)
Facebook has fixed this issue, as you can see from their post at:
http://bugs.developers.facebook.com/show_bug.cgi?id=10531
I see where the problem is, but not sure what if anything we can do about it. It happens in the UIWebView Delegate method in the FBDialog class. If you click the Skip button, the request.URL is populated with 'fbconnect:success', it should really be 'fbconnect:cancel' but other people have already pointed out this problem out before. Our problem is that when you click the Publish button, the request.URL should read 'fbconnect:success' however, it ends up containing 'http://www.facebook.com/fbconnect/prompt_feed.php', so, it never calls dismissWithSuccess:YES or dialogDidSucceed.
I can't find anyplace where the Publish button's post URL is set, but if we can change it to fbconnect:success, it might work.
FBDialog.m
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
NSURL* url = request.URL;
if ([url.scheme isEqualToString:#"fbconnect"]) {
if ([url.resourceSpecifier isEqualToString:#"cancel"]) {
[self dismissWithSuccess:NO animated:YES];
} else {
[self dialogDidSucceed:url];
}
return NO;
} else if ([_loadingURL isEqual:url]) {
return YES;
} else if (navigationType == UIWebViewNavigationTypeLinkClicked) {
if ([_delegate respondsToSelector:#selector(dialog:shouldOpenURLInExternalBrowser:)]) {
if (![_delegate dialog:self shouldOpenURLInExternalBrowser:url]) {
return NO;
}
}
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
} else {
return YES;
}
}

FBDialog cancel button callback

When user hits the Cancel button in the FBStreamDialog, which inherits from FBDialog, I am having trouble differentiating it from when user clicks on the Publish button. Seems that the callback FBDialog dismissWithSuccess is always passed with the status:NO regardless of which button is clicked. What am I doing wrong? Thanks!
Here's the class that handles all the FBConnect in my app:
#interface SocialMediaViewController : UIViewController <FBSessionDelegate, FBRequestDelegate, FBDialogDelegate> {...
Here's how I instantiated the login.
FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:self.fbSession] autorelease];
dialog.delegate = self;
[dialog show];
Here's how I instantiated the FBStreamDialog.
FBStreamDialog* dialog = [[FBStreamDialog alloc] init];
dialog.delegate = self;
dialog.userMessagePrompt = #"Enter additional comment:";
dialog.attachment = [NSString stringWithFormat:#"{\"name\":\"My name string %#\"," "\"href\":\"http://xyz.com/\"," "\"caption\":\"placeholder-%#\",\"description\":\"%#\"," "\"properties\":{\"More like this\":{\"text\":\"XYZ website\",\"href\":\"http://XYZ.com/\"}}}", self.curReview.businessName, self.curReview.reviewType, self.curReview.reviewDetail];
[dialog show];
Add the following as the first line in FBDialog.m / webViewDidFinishLoad :
[_webView stringByEvaluatingJavaScriptFromString:#"document.getElementById('cancel').onclick = function onclick(event) { window.location.href = 'fbconnect:cancel'; }"];
Bear in mind that Facebook doesn't let you "punish" users for canceling :-)
