How to get user name and email id for Facebook SDK?
提问by Peer Mohamed Thabib
The code I have used
我用过的代码
if (FBSession.activeSession.state == FBSessionStateOpen
|| FBSession.activeSession.state == FBSessionStateOpenTokenExtended) {
// Close the session and remove the access token from the cache
// The session state handler (in the app delegate) will be called automatically
[FBSession.activeSession closeAndClearTokenInformation];
// If the session state is not any of the two "open" states when the button is clicked
} else {
// Open a session showing the user the login UI
// You must ALWAYS ask for basic_info permissions when opening a session
[FBSession openActiveSessionWithReadPermissions:@[@"basic_info,email"]
allowLoginUI:YES
completionHandler:
^(FBSession *session, FBSessionState state, NSError *error) {
// Retrieve the app delegate
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
// Call the app delegate's sessionStateChanged:state:error method to handle session state changes
[appDelegate sessionStateChanged:session state:state error:error];
}];
}

使用以下代码
FBSession *session = [[FBSession alloc] initWithPermissions:@[@"basic_info", @"email"]];
[FBSession setActiveSession:session];
[session openWithBehavior:FBSessionLoginBehaviorForcingWebView
completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (!error) {
NSLog(@"accesstoken %@",[NSString stringWithFormat:@"%@",session.accessTokenData]);
NSLog(@"user id %@",user.id);
NSLog(@"Email %@",[user objectForKey:@"email"]);
NSLog(@"User Name %@",user.username);
}
}];
}
}];

if ([FBSDKAccessToken currentAccessToken]) {
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"email,name,first_name"}]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

// use facebook SDK 3.8
add the following methods in AppDelegate.m
在 AppDelegate.m 中添加以下方法
-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication: (NSString *)sourceApplication annotation:(id)annotation
{
return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication fallbackHandler:^(FBAppCall *call)
{
NSLog(@"Facebook handler");

}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
[FBAppEvents activateApp];
[FBAppCall handleDidBecomeActive];
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
- (void)applicationWillTerminate:(UIApplication *)application
{
[FBSession.activeSession close];
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

se the follwing code in your viewcontroler .h
在您的视图控制器 .h 中查看以下代码

// apply the below code to your view controller.m
// 将以下代码应用到您的视图 controller.m

loginview.frame=CGRectMake(60, 50, 200, 50);
loginview.delegate=self;
[loginview sizeToFit];
[self.view addSubview:loginview];
}
-(void)loginViewShowingLoggedInUser:(FBLoginView *)loginView
{
self.lblCreate.enabled=YES;

Create a dictionary :
创建字典：
class ViewController: UIViewController {
var dict : NSDictionary!
}
Fetching the data :
获取数据：
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
self.dict = result as NSDictionary
println(self.dict)
NSLog(self.dict.objectForKey("picture")?.objectForKey("data")?.objectForKey("url") as String)
}
})
}
Output should be :
输出应该是：
{
email = "[email protected]";
"first_name" = Karthi;
id = 924483474253864;
"last_name" = keyan;
name = "karthi keyan";
picture = {
data = {
"is_silhouette" = 0;
url = "XXXXXXX";
};
};
}

Make the following request after successfully login in, you don't read publish_actions permissions for it.
成功登录后发出以下请求，您没有读取它的publish_actions权限。
/* make the API call */
[FBRequestConnection startWithGraphPath:@"/me"
parameters:nil
HTTPMethod:@"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
/* handle the result */
}];

You can get these information by using the NSDictionary: NSDictionary<FBGraphUser> *user,
you just need to use objectforkeyto access these values like :
您可以通过使用 来获取这些信息NSDictionary: NSDictionary<FBGraphUser> *user，您只需要使用objectforkey来访问这些值，例如：
[user objectForKey:@"id"],
[user objectForKey:@"username"],
[user objectForKey:@"email"].
Hopefully it will work for you.
希望它对你有用。

This currently works with the latest version of the FB SDK:
这目前适用于最新版本的 FB SDK：
Somewhere before set up the FB login button correctly (assuming self.facebookLoginButtonis initialized via IB):
在正确设置 FB 登录按钮之前的某个地方（假设self.facebookLoginButton是通过 IB 初始化的）：
self.facebookLoginButton.readPermissions = @[@"public_profile", @"email"];
self.facebookLoginButton.delegate = self;
Then in loginButton:didCompleteWithResult:error::
然后在loginButton:didCompleteWithResult:error:：
- (void)loginButton:(FBSDKLoginButton *)loginButton
didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result
error:(NSError *)error
{
NSDictionary *parameters = @{@"fields":@"email,name"};
FBSDKGraphRequest *graphRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:parameters];
[graphRequest startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
{
LogInfo(@"fetched user:%@", result);
}];
}

The username field of the User object has been removed, and does not exist in Graph API v2.0. In v2.0 of the API is there is no way to get the FB username of a user.you can use app scope id though as username.
User 对象的 username 字段已被移除，在 Graph API v2.0 中不存在。在 API 的 v2.0 中，无法获取用户的 FB 用户名。您可以使用应用范围 ID 作为用户名。
Facebook got rid of the username because the username is one way of sending emails via Facebook. For example, given the url http://www.facebook.com/sebastian.trugthe corresponding Facebook email would be [email protected] which, if emailed, would be received to messages directly (if the message setting is set to public), otherwise to the other inbox.
Facebook 去掉了用户名，因为用户名是通过 Facebook 发送电子邮件的一种方式。例如，给定 url http://www.facebook.com/sebastian.trug，相应的 Facebook 电子邮件将是 [email protected]，如果通过电子邮件发送，它将直接接收到消息（如果设置了消息设置到公共），否则到另一个收件箱。
