I am using facebook sdk for ios for the first time. I have been facing a weird problem. The facebook sdk lets me logout but wont let me login with a different user. do you guys have any idea how to solve this.
I am pasting something that i have used for logout..
- (IBAction)buttonTouched:(id)sender
{
// If the session state is any of the two "open" states when the button is clicked
if (FBSession.activeSession.state == FBSessionStateOpen
|| FBSession.activeSession.state == FBSessionStateOpenTokenExtended) {
// Close the session and remove the access token from the cache
// The session state handler (in the app delegate) will be called automatically
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];
}
}
[FBSession.activeSession closeAndClearTokenInformation];
// If the session state is not any of the two "open" states when the button is clicked
} else {
// Open a session showing the user the login UI
// You must ALWAYS ask for public_profile permissions when opening a session
[FBSession openActiveSessionWithReadPermissions:@[@"public_profile"]
allowLoginUI:YES
completionHandler:
^(FBSession *session, FBSessionState state, NSError *error) {
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (error) {
NSLog(@"error:%@",error);
} else {
NSLog(@"user dictionary %@",user);
// retrive user's details at here as shown below
NSLog(@"FB user first name:%@",user.first_name);
NSLog(@"FB user last name:%@",user.last_name);
NSLog(@"FB user birthday:%@",user.birthday);
NSLog(@"FB user location:%@",user.location);
NSLog(@"FB user username:%@",user.username);
NSLog(@"FB user gender:%@",[user objectForKey:@"gender"]);
NSLog(@"email id:%@",[user objectForKey:@"email"]);
NSLog(@"location:%@", [NSString stringWithFormat:@"Location: %@\n\n",
user.location[@"name"]]);
}
}];
// Retrieve the app delegate
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
// Call the app delegate's sessionStateChanged:state:error method to handle session state changes
[appDelegate sessionStateChanged:session state:state error:error];
}];
}
}
I am getting a text "You have already authorized Myappname" logging in for the second time after logout. But i am not getting the option for other users to get logged in.
Any help will be appreciated. Thanks in advance.
