How to get user info from Facebook SDK in iOS?
提问by Peer Mohamed Thabib
How to get user name when user session is open.I tried the session login sample from Facebook sdk samples. if any one knows the solution please help me out. Thanks in advance.
如何在用户会话打开时获取用户名。我尝试了 Facebook sdk 示例中的会话登录示例。如果有人知道解决方案，请帮助我。提前致谢。
- (IBAction)buttonClickHandler:(id)sender {
// get the app delegate so that we can access the session property
SLAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
// this button's job is to flip-flop the session from open to closed
if (appDelegate.session.isOpen) {
// if a user logs out explicitly, we delete any cached token information, and next
// time they run the applicaiton they will be presented with log in UX again; most
// users will simply close the app or switch away, without logging out; this will
// cause the implicit cached-token login to occur on next launch of the application
//hear i need to fetch user name ?
[appDelegate.session closeAndClearTokenInformation];
} else {
if (appDelegate.session.state != FBSessionStateCreated) {
// Create a new, logged out session.
appDelegate.session = [[FBSession alloc] init];
}
// if the session isn't open, let's open it now and present the login UX to the user
[appDelegate.session openWithCompletionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// and here we make sure to update our UX according to the new session state
[self updateView];
}];
}
}

After login authentication, you can get details from active FBSession like below
登录验证后，您可以从活动的 FBSession 中获取详细信息，如下所示
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *user,
NSError *error) {
if (!error) {
NSString *firstName = user.first_name;
NSString *lastName = user.last_name;
NSString *facebookId = user.id;
NSString *email = [user objectForKey:@"email"];
NSString *imageUrl = [[NSString alloc] initWithFormat: @"http://graph.facebook.com/%@/picture?type=large", facebookId];
}
}];
}
Update:Instead of iduse objectIDproperty, after release of version v3.14.1(May 12, 2014), the idproperty has been deprecated
更新：代替iduseobjectID属性，v3.14.1 版本发布后（2014 年 5 月 12 日），该id属性已被弃用
NSString *facebookId = user.objectID;

Hi you can get the details of Facebook user like:
嗨，您可以获取 Facebook 用户的详细信息，例如：
- (void)sessionStateChanged:(NSNotification*)notification {
if ([[FBSession activeSession] isOpen]) {
[FBRequestConnection
startForMeWithCompletionHandler:^(FBRequestConnection *connection,
id<FBGraphUser> user,
NSError *error) {
if (! error) {
//details of user
NSLog(@"User details =%@",user);
}
}];
}else {
[[FBSession activeSession] closeAndClearTokenInformation];
}
}
Thanks
谢谢

if (!error && state == FBSessionStateOpen){
NSLog(@"Session opened");
// Show the user the logged-in UI
FBRequest* userupdate = [FBRequest requestWithGraphPath:@"me" parameters: [NSMutableDictionary dictionaryWithObject:@"picture.type(large),id,birthday,email,gender,username,name,first_name" forKey:@"fields"] HTTPMethod:@"GET"];
[drk showWithMessage:nil];
[userupdate startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,NSError *error)
{
NSLog(@"dict = %@",result);
}];
return;
}

FBSDKGraphRequest(graphPath: "me", parameters: nil).startWithCompletionHandler({ (connection, object, error) in
guard let user = object as? Dictionary<String, NSObject> else {
alert("facebook sdk gave me trash object \(object)")
return
}
if let error = error {
alert(error.localizedDescription)
}
else {
if let userID = user["id"] {
// gr8t success
}
}
})

-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id)user {
-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id)user {
NSLog(@"user facebook details:%@",user.objectID);
}
}
You can implement this delegate method.
您可以实现此委托方法。
