我在我的应用程序中实现了facebook登录集成的概念。 1 ---->我能够登录facebook登录,但在用户登录后我想继续使用我的应用程序,即出现三个标签项的tabbarController,同时我需要获取facebook用户详细信息(电子邮件,名字,姓氏等)
但我无法检索细节。我不明白我哪里出错了。
在我的ViewController.m中:
- (IBAction)performLogin:(id)sender
{
AppAppDelegate *appDelegate = (AppAppDelegate *) [[UIApplication sharedApplication] delegate];
[appDelegate openSessionWithAllowLoginUI:YES];
UITabBarController *tabBarController=[[UITabBarController alloc]init];
SearchViewController *searchViewController=[[SearchViewController alloc]initWithNibName:@"SearchViewController" bundle:nil];
UserProfile *userprofile=[[UserProfile alloc]initWithNibName:@"UserProfile" bundle:nil];
userprofile.title=@"My Profile";
LogOut *logout=[[LogOut alloc]initWithNibName:@"LogOut" bundle:nil];
logout.title=@"Log Out";
tabBarController.viewControllers=[NSArray arrayWithObjects:searchViewController,userprofile,logout, nil];
[self presentModalViewController:tabBarController animated:YES];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(sessionStateChanged:)
name:FBSessionStateChangedNotification
object:nil];
}
- (void)sessionStateChanged:(NSNotification*)notification {
if (FBSession.activeSession.isOpen) {
[FBRequestConnection
startForMeWithCompletionHandler:^(FBRequestConnection *connection,
id<FBGraphUser> user,
NSError *error) {
if (!error) {
NSString *fbUserEmail= @"";
NSLog(@"%@",user);
fbUserEmail=[user objectForKey:@"email"];
AppAppDelegate *appDelegate = (AppAppDelegate *) [[UIApplication sharedApplication] delegate];
appDelegate.fbEmail=fbUserEmail;
}
}
];
}
}
但是这里没有显示facebook登录页面我得到tabbarController而我无法获取用户详细信息。
如何首先显示facebook登录页面,然后使用tabbarController显示用户详细信息。

您可以使用Facebook Graph API获取Facebook用户详细信息,下面链接演示使用Graph API获取基本用户详细信息。点击此处:http://www.raywenderlich.com/1578/how-to-get-a-user-profile-with-facebooks-new-graph-api-from-your-iphone-app
