I am implementing Facebook integration using FBConnct and it works fine but when I
want to log out from the Facebook it doesn't work.
My code is as follows:
- (IBAction)logOutbuttonPressed:(id)sender {
[Facebook logout:self];
}
- (void)fbDidLogout {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults removeObjectForKey:#"FBAccessTokenKey"];
[defaults removeObjectForKey:#"FBExpirationDateKey"];
NSLog(#" after %#",facebook.accessToken);
NSLog(#" date%#",facebook.expirationDate);
[defaults synchronize];
}
- (void)logout:(id<FBSessionDelegate>)delegate {
[self logout];
if (delegate != self.sessionDelegate &&
[delegate respondsToSelector:#selector(fbDidLogout)]) {
[delegate fbDidLogout];
}
+(void)fbDidLogout
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:#"FBAccessTokenKey"])
{
[defaults removeObjectForKey:#"FBAccessTokenKey"];
[defaults removeObjectForKey:#"FBExpirationDateKey"];
[defaults synchronize];
}
// Hide the publish button.
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
NSString* domainName = [cookie domain];
NSRange domainRange = [domainName rangeOfString:#"facebook"];
if(domainRange.length > 0)
{
[storage deleteCookie:cookie];
}
}
}
You need to implement this code for facebook logout as well
- (void)fbDidLogout {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults removeObjectForKey:#"FBAccessTokenKey"];
[defaults removeObjectForKey:#"FBExpirationDateKey"];
NSLog(#" after %#",facebook.accessToken);
NSLog(#" date%#",facebook.expirationDate);
[defaults synchronize];
// Finding the Facebook Cookies and deleting them
NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray* facebookCookies = [cookies cookiesForURL:
[NSURL URLWithString:#"http://login.facebook.com"]];
for (NSHTTPCookie* cookie in facebookCookies) {
[cookies deleteCookie:cookie];
}
fbGraph = nil;
}
Try this
import 'FBConnect.h'
in ur second view controller
then .......
FBSession *session = [FBSession session]; [session logout];
Call this method to logout from facebook.
- (void)logOutFB {
fbGraph.accessToken = nil;
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
NSString* domainName = [cookie domain];
NSRange domainRange = [domainName rangeOfString:#"facebook"];
if(domainRange.length > 0)
{
[storage deleteCookie:cookie];
}
}
}

}
Please help as I am trying to solve this for hours.strong text
I am integrating twitter in my app for sharing a text. My architecture of twitter integration is I have two Button _btnTwitter and _btntwitteLogout and when the user successfully login the twitter his name will display in _btntwitterLogout as title.
When the user tap the _btntwitterLogout it logs out the twitter and logout button hides and login button comes.every thing went ok.but when the user tap the login button(_btnTwitter) the Twitter login popup cmes for login purpose,here is the problem that am facing ,when the popup comes the user tap the cancel button of that popup the popup disappears and here the previous username of the user in the logout button.it didn't changes. I have put user defaults to check.
-(IBAction)_clickbtnTwitter:(id)sender
{
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:#"Twitter_logged"];
[_btntwitterLogeout setTitle:nil forState:UIControlStateNormal];
_btntwitterLogeout.hidden = NO;
_btnTwitter.hidden=YES;
if (_engine) return;
_engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate: self];
_engine.consumerKey = kOAuthConsumerKey;
_engine.consumerSecret = kOAuthConsumerSecret;
UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine: _engine delegate: self];
if (controller)
[self presentModalViewController: controller animated: YES];
else {
[_engine sendUpdate: [NSString stringWithFormat: #"Already Updated. %#", [NSDate date]]];
}
}
}
then logout code
-(IBAction)_clickbtntwitterlogeout:(id)sender
{
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:#"Twitter_logged"];
crosstwitterimage.hidden = YES;
[_btntwitterLogeout setTitle:nil forState:UIControlStateNormal];
_btntwitterLogeout.hidden = YES;
_btnTwitter.hidden=NO;
_btnTwittermain.enabled = NO;
[_engine clearAccessToken];
[_engine clearsCookies];
[_engine setClearsCookies:YES];
[[NSUserDefaults standardUserDefaults] removeObjectForKey:#"authData"];
[[NSUserDefaults standardUserDefaults]removeObjectForKey:#"authName"];
NSLog(#"%#",[[NSUserDefaults standardUserDefaults]valueForKey:#"authName"]);
NSLog(#"%#",[[NSUserDefaults standardUserDefaults]valueForKey:#"authData"]);
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:#"Twitter_logged"];
[_engine release];
_engine=nil;
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
NSString* domainName = [cookie domain];
NSRange domainRange = [domainName rangeOfString:#"twitter"];
if(domainRange.length > 0)
{
[storage deleteCookie:cookie];
}
}
}
in viewwillappear
BOOL logged = [[NSUserDefaults standardUserDefaults] boolForKey:#"Twitter_logged"];
;
if (logged == YES) {
_btnTwitter. hidden = YES;
_btntwitterLogeout.hidden = NO;
crosstwitterimage.hidden = NO;
_btnTwittermain.enabled =YES;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
//Checks if there is a saved User Name
if([defaults objectForKey:#"kTwitterUserName"])
{
NSString *username = [defaults objectForKey:#"kTwitterUserName"];
[_btntwitterLogeout setTitle:username forState:UIControlStateNormal];
crosstwitterimage.hidden = NO;
}
}
else
{
_btnTwitter. hidden = NO;
crosstwitterimage.hidden = YES;
[_btntwitterLogeout setTitle:nil forState:UIControlStateNormal];
_btnTwittermain.enabled =NO;
crosstwitterimage.hidden = YES;
}
but when i tap the cancel button in loginwindow of twitter,an comes back the username with the logout button shows ,if the user is already logedout from twitter.
is there any problem in my code.
thanks in advance.
EDIT
#pragma mark SA_OAuthTwitterEngineDelegate
- (void) storeCachedTwitterOAuthData: (NSString *) data forUsername: (NSString *) username {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject: data forKey: #"authData"];
[defaults synchronize];
}
- (NSString *) cachedTwitterOAuthDataForUsername: (NSString *) username {
return [[NSUserDefaults standardUserDefaults] objectForKey: #"authData"];
}
#pragma mark SA_OAuthTwitterControllerDelegate
- (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username {
NSLog(#"Authenicated for %#", username);
[_btntwitterLogeout setTitle:username forState:UIControlStateNormal];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:username forKey:#"kTwitterUserName"];
[defaults synchronize];
}
- (void) OAuthTwitterControllerFailed: (SA_OAuthTwitterController *) controller {
NSLog(#"Authentication Failed!");
}
- (void) OAuthTwitterControllerCanceled: (SA_OAuthTwitterController *) controller {
NSLog(#"Authentication Canceled.");
}
#pragma mark TwitterEngineDelegate
- (void) requestSucceeded: (NSString *) requestIdentifier {
NSLog(#"Request %# succeeded", requestIdentifier);
}
- (void) requestFailed: (NSString *) requestIdentifier withError: (NSError *) error {
NSLog(#"Request %# failed with error: %#", requestIdentifier, error);
}
Yes there is a problem. Whenever you hit the _btnTwitter, you are setting the Twitter_logged to yes. That's not correct. You should only set it to yes when there is a successful login. That is when the user has NOT hit cancel on the twitter login window.
In other words, you need to set the Twitter_logged to YES once the user has actually logged in, not when the user clicked on the button _btnTwitter
Seems like SA_OAuthTwitterController has a delegate property pointing to self. You should handle code to set Twitter_logged YES in that delegate method.
Hope that helps.
Edit:
Given the latest code here is where you should add the NsUserDefaults data
- (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username {
NSLog(#"Authenicated for %#", username);
[_btntwitterLogeout setTitle:username forState:UIControlStateNormal];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:username forKey:#"kTwitterUserName"];
[defaults setBool:YES forKey:#"Twitter_logged"]; // Right here - mbh
[defaults synchronize];
}
i'm using Facebook native API for sharing in my iPhone App, i need to know as soon as user logged in i need his username, how can i get this?
Any help is appriciated in advance.
You can use Graph API to do this. Just make a request in fbDidLogin delegate method:
- (void)fbDidLogin {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:#"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:#"FBExpirationDateKey"];
[defaults synchronize];
[facebook requestWithGraphPath: #"me" andDelegate: self];
}
And then you can get all the information about current user in didLoad method:
- (void)request:(FBRequest*)request didLoadRawResponse:(NSData*)data
{
NSString *response = [[NSString alloc] initWithData: data
encoding:NSUTF8StringEncoding];
NSLog(#"%#", response);
[response release];
}
- (void) request:(FBRequest*)request didLoad:(id)result
{
if ([result isKindOfClass:[NSDictionary class]])
{
NSString *name = [result objectForKey: #"name"];
NSString *fbID = [result objectForKey:#"id"];
}
}
Hy, i am trying to make from Facebook IOS SDK (Octomber 2011) a class of my own in where i can make all the methods and functions that i need and just import this class in any of my application view controllers and call it.
So this way i don't need to do all the initialization and delegation to the controllers in where i use the facebook.
So i want to do like this, [myfacebookclass initwithappID:myappid]
[myfacebookclass postmessage:#"some message"];
The thing is when i am seting authorizeWithFBAppAuth:YES safariAuth:YES flags in facebook.m ( the original class) and i do a postmessage it redirects me on Facebook Application or Safari and check's for permision, i hit ok and then redirects me in my application and doesn't post message.
WHen i am trying to post message i do like this :
This is in my own facebook class
myfacebookclass *facebook2;
+(void)initWithAppID:(NSString*) facebookAppId {
if (facebook2 == nil) {
facebook2 = [myfacebookclass new];
[facebook2 setWithAppId:facebookAppId];
}
}
- (void) postMessage1:(NSString *)messageToPost {
if ([self.facebook isSessionValid]) {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
self.applicationID, #"api_key",
messageToPost, #"message",
nil];
[self.facebook requestWithGraphPath:#"me/feed" andParams:params andHttpMethod:#"POST" andDelegate:self];
} else {
NSArray * neededPermissions = [[[NSArray alloc] initWithObjects:#"user_about_me", #"publish_stream", nil] autorelease];
[self.facebook authorize:neededPermissions];
}
}
+ (void)postMessage:(NSString*) message {
[facebook2 postMessage1:message];
}
I also implemented:
(BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [facebook handleOpenURL:url];
}
i've didn't modified facebook.m or other classes in Facebook IOS SDK.
a good practice when making a singleton class is to use shared instance. Correct singleton also has to include some memory management overridden methods. In your case it can be done like this:
#implementation FacebookManager
static FacebookManager *mySharedFacebookManager;
+ (FacebookManager*)sharedFacebookManager {
#synchronized(self) {
if(mySharedFacebookManager == nil) {
mySharedFacebookManager = [[self alloc] init];
}
}
return mySharedFacebookManager;
}
+ (id)allocWithZone:(NSZone *)zone {
#synchronized(self) {
if(mySharedFacebookManager == nil) {
mySharedFacebookManager = [super allocWithZone:zone];
return mySharedFacebookManager;
}
}
return nil;
}
- (id)copyWithZone:(NSZone *)zone {
return self;
}
- (id)retain {
return self;
}
- (unsigned)retainCount {
return UINT_MAX;
}
- (oneway void)release {
}
- (id)autorelease {
return self;
}
In your case you may have Facebook type object as ivar, and some methods to wrap over FB API, for example like this:
- (id)init {
self = [super init];
if(self) {
facebook = [[Facebook alloc] initWithAppId:FB_APP_ID andDelegate:self];
// restore previous session
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:#"FBAccessTokenKey"]
&& [defaults objectForKey:#"FBExpirationDateKey"]) {
facebook.accessToken = [defaults objectForKey:#"FBAccessTokenKey"];
facebook.expirationDate = [defaults objectForKey:#"FBExpirationDateKey"];
}
...
}
return self;
}
- (void)login {
NSArray *permissions = [NSArray arrayWithObjects: #"user_about_me", #"publish_stream", nil];
[facebook authorize:permissions];
}
- (void)postToFeed:(NSString*)messageToPost {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
messageToPost, #"message",
nil];
[facebook requestWithGraphPath:#"me/feed"
andParams:params
andHttpMethod:#"POST"
andDelegate:self];
}
From other classes which have to deal with Facebook the construction is simple:
[[FacebookManager sharedFacebookManager] login];
...
[[FacebookManager sharedFacebookManager] postToFeed:#"Hello World!"];
I hope this snippets will help you.
To manage your facebook session you have to remember accessToken manually in FBSessionDelegate methods like that:
- (void)fbDidLogin {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:#"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:#"FBExpirationDateKey"];
[defaults synchronize];
}
- (void)fbDidLogout {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults removeObjectForKey:#"FBAccessTokenKey"];
[defaults removeObjectForKey:#"FBExpirationDateKey"];
[defaults synchronize];
}
I am attempting to write a Facebook integration in an iPhone app I'm working on. I have it logging in just fine, but I don't like the idea of being able to turn a feature on without being able to turn it off. So, in working on the logout functionality, I have been caught in a snag.
- (IBAction) logoutClicked:(id)sender {
if (fbLoggedIn)
{
FBSession * mySession = [FBSession session];
[mySession logout];
}
}
- (void)sessionDidLogout:(FBSession*)session
{
NSLog(#"Session logged out.");
[theLoginButton setTitle:#"Facebook Time!" forState:UIControlStateNormal];
fbLoggedIn = FALSE;
theLogoutButton.enabled = NO;
theLogoutButton.alpha = 0;
}
The logoutClicked method responds to a button in my xib. The delegate method is not getting called. I have tried setting the Facebook session as a property in my ViewController in order to store/access the data across methods, but that didn't seem to work either. Anybody have any solutions?
Is the sessionDidLogout implemented in a class which implements FBSessionDelegate?
And is it an instance of that class that you passed as a delegate when creating the session with the method [FBSession sessionForApplication:#"XXX" secret:#"YYY" delegate:(DELEGATE)] ?
This works for me:
(void)logout {
//self.sessionDelegate = delegate;
appDelegate.facebook.accessToken = nil;
appDelegate.facebook.expirationDate = nil;
NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray* facebookCookies = [cookies cookiesForURL:[NSURL URLWithString:#"http://login.facebook.com"]];
for (NSHTTPCookie* cookie in facebookCookies) {
[cookies deleteCookie:cookie];
}
NSLog(#"Log out");
// Remove saved authorization information if it exists
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
if ([userDefaults objectForKey:#"FBAccessTokenKey"]) {
[userDefaults removeObjectForKey:#"FBAccessTokenKey"];
[userDefaults removeObjectForKey:#"FBExpirationDateKey"];
[userDefaults synchronize];
}
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
NSString* domainName = [cookie domain];
NSRange domainRange = [domainName rangeOfString:#"facebook"];
if(domainRange.length > 0)
{
[storage deleteCookie:cookie];
}
}
}
Put this code for logout. I got this from this link.
- (void) fbDidLogout {
NSLog(#"Log out");
// Remove saved authorization information if it exists
if ([userDefaults objectForKey:#"FBAccessTokenKey"]) {
[userDefaults removeObjectForKey:#"FBAccessTokenKey"];
[userDefaults removeObjectForKey:#"FBExpirationDateKey"];
[userDefaults synchronize];
}
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
NSString* domainName = [cookie domain];
NSRange domainRange = [domainName rangeOfString:#"facebook"];
if(domainRange.length > 0)
{
[storage deleteCookie:cookie];
}
}
}
