    IBOutlet UITextField *txtPassword;
    IBOutlet UILabel *lblMessage;
    IBOutlet FBLoginButton* _loginButton;

Answer 1

Now i found out that when am calling - (void)logout

its checking if (_sessionKey) condition....

my condition giving false when i call from another view controller..so it will o to else part.. so it will call unsave function..

• (void)logout {

  if (_sessionKey) { NSLog(@"Logout clicked with session key");

  for (id delegate in _delegates) { if ([delegate respondsToSelector:@selector(session:willLogout:)]) { [delegate session:self willLogout:_uid]; } }

  // Remove cookies that UIWebView may have stored NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage]; NSArray* facebookCookies = [cookies cookiesForURL: [NSURL URLWithString:@"http://login.facebook.com"]]; for (NSHTTPCookie* cookie in facebookCookies) { [cookies deleteCookie:cookie]; }

  _uid = 0; [_sessionKey release]; _sessionKey = nil; [_sessionSecret release]; _sessionSecret = nil; [_expirationDate release]; _expirationDate = nil; [self unsave];

  for (id delegate in _delegates) { if ([delegate respondsToSelector:@selector(sessionDidLogout:)]) { [delegate sessionDidLogout:self]; } } } else { NSLog(@"Logout clicked with out session key");

  [self unsave]; } }

So how i can retain my sessionkey in another viewcontroller ?

any body please answer me....thanks in advance..
