我已经在我的应用程序中实现了 facebook 登录集成的概念。1---->我能够进行facebook登录,但在用户facebook登录后我想继续我的应用程序,即出现一个带有三个选项卡项目的tabbarController,同时我需要获取facebook用户详细信息(电子邮件、名字、姓氏等)
但我无法检索详细信息。我不明白我要去哪里错了。
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;
}
}
];
}
}
但是在这里没有显示 facebook 登录页面,我得到了 tabbarController,我无法检索用户详细信息。
如何先显示 facebook 登录页面,然后显示 tabbarController 和用户详细信息。?
