PFFacebookUtils logInWithPermissions在模拟器上失败

我正在将我的iOS应用程序与Parse和Facebook集成.它在我的iPhone 4s上工作正常 - 运行iOS 6 - 但是当我在我的xCode 5模拟器上尝试测试帐户时它失败了.

当我用facebook按钮登录时,我会看到一个屏幕说:你已经授权Test999(我的应用程序名称.)当我打电话给这一行时,就会发生这种情况:

[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) 

我按OK.它将我发送到"您必须先登录"屏幕.我输入了我的用户名和密码,然后按下登录状态 - 我将被发送回您已经授权的Test999.我按OK - 我看到一个空白视图,左上方有一个x来关闭它.没有别的事可做,所以我推它,我被送回"你必须先登录"屏幕.

因此,无法使用模拟器登录.我试图"重置内容和设置",但它没有帮助.

关于类似问题的答案后,我尝试添加一个reconnectWithFb方法(下面),我还将我的Facebook sdk更新到版本3.9.什么都没有帮助.

这是我用facebook方法登录的:

[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {

if (!user) {
    if (!error) {
        NSLog(@"Uh oh. The user cancelled the Facebook login.");
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"User cancelled facebook login" message:@"Uh oh. The user cancelled the Facebook login." delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Dismiss", nil];
        [alert show];
    } else {
        NSLog(@"welcome screen loginWithFB: Uh oh. An error occurred: %@", error);
        [self performSelector:@selector(reconnectWithFB) withObject:nil afterDelay:0.5];
    }
} else if (user.isNew) {
    NSLog(@"New user with facebook signed up and logged in!");
} else {
    NSLog(@"User with facebook logged in!");        
    FBRequest *request = [FBRequest requestForMe];
    [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
        if (!error) {
            NSString *facebookUsername = [result objectForKey:@"name"];
            [PFUser currentUser].username = facebookUsername;
            [[PFUser currentUser] setObject:[result objectForKey:@"id"] forKey:@"facebookid"];
            [[PFUser currentUser] saveEventually];
            [[NSNotificationCenter defaultCenter] postNotificationName:kUsersToWatchNotification object:result];
        } else {
            NSLog(@"Error getting the FB username %@", [error description]);
        }
    }];
}

和我的reconnectWithFB(在模拟器上总是有一个空的fbAccounts数组:)

-(void) reconnectWithFB {
    NSLog(@"reconnectWithFB called");
    ACAccountStore *accountStore;
    ACAccountType *accountTypeFB;
    if ((accountStore = [[ACAccountStore alloc] init]) && (accountTypeFB = [accountStore  accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook] ) ){
    NSArray *fbAccounts = [accountStore accountsWithAccountType:accountTypeFB];

    NSLog(@"fbAccounts %@", fbAccounts);

    id account;
    if (fbAccounts && [fbAccounts count] > 0 && (account = [fbAccounts objectAtIndex:0])){
        [accountStore renewCredentialsForAccount:account completion:^(ACAccountCredentialRenewResult renewResult, NSError *error) {
                //we don't actually need to inspect renewResult or error.
                if (error){
                    NSLog(@"error in reconnectWithFB %@", error);
                }
        }];
      } 
   }
}

任何有关这方面的帮助将不胜感激.
