註銷Facebook的sdk 3.08

我有一個問題，我的Facebook應用程序的斷開是一個簡單的應用程序，上傳一張照片到Facebook。要登錄，您需要註銷safari，但不能完全註銷並在我的帳戶中執行下一次登錄。我在php中看到了幾個選項，但沒有工作。附帶代碼註銷Facebook的sdk 3.08

- (void)viewDidLoad 
{ 
[buttonPost setHidden:NO]; 

     FBLoginView *loginview = [[FBLoginView alloc] initWithPermissions:[NSArray arrayWithObject:@"publish_actions"]]; 

     loginview.frame = CGRectOffset(loginview.frame, 5, 5); 
     loginview.delegate = self; 

     [self.view addSubview:loginview]; 

     [loginview sizeToFit]; 
} 

- (IBAction)Post:(UIButton *)sender{ 
    [FBRequestConnection startForUploadPhoto:self.imageScreen completionHandler:^(FBRequestConnection *connection, id result, NSError *error) 
     { 
      [self showAlert:@"Photo Post" result:result error:error]; 
     }]; 
} 

- (void)loginViewShowingLoggedOutUser:(FBLoginView *)loginView { 
    [self.buttonPost setHidden:YES]; 

    self.labelFirstName.text = nil; 


} 
- (void)loginViewShowingLoggedInUser:(FBLoginView *)loginView { 
    // first get the buttons set for login mode 
    [self.buttonPost setHidden:NO]; 

} 
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user { 
    // here we use helper properties of FBGraphUser to dot-through to first_name and 
    // id properties of the json response from the server; alternatively we could use 
    // NSDictionary methods such as objectForKey to get values from the my json object 
    self.labelFirstName.text = [NSString stringWithFormat:@"Hello %@!", user.first_name]; 
    // setting the profileID property of the FBProfilePictureView instance 
    // causes the control to fetch and display the profile picture for the user 
    self.loggedInUser = user; 
} 

- (void)showAlert:(NSString *)message 
      result:(id)result 
      error:(NSError *)error { 

    NSString *alertMsg; 
    NSString *alertTitle; 
    if (error) { 
     alertMsg = error.localizedDescription; 
     alertTitle = @"Error"; 
    } else { 
     NSDictionary *resultDict = (NSDictionary *)result; 
     alertMsg = [NSString stringWithFormat:@"Successfully posted", 
        message, [resultDict valueForKey:@"id"]]; 
     alertTitle = @"Success"; 
    } 

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:alertTitle 
                 message:alertMsg 
                 delegate:nil 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
    [alertView show]; 
}

此問題與Safari的Cookie和緩存機制有關。

不幸的是，我知道讓Safari忘記以前的登錄憑據的唯一方法是清除設備設置中的Cookie和數據。

我還沒有真正嘗試過，但我相當肯定，當您使用FBSession而不是FBLoginView時，也會發生這種情況。 Clear Safari's cookies and Data on iPad
