如何獲取Facebook SDK的用戶名和電子郵件ID？

的代碼，我從這個代碼，我需要獲得用戶名和郵件ID使用如何獲取Facebook SDK的用戶名和電子郵件ID？

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]; 
     }]; 
    }

。如果有人知道解決方案，請提前幫助我。

「user.username」不起作用。改用「user [@」name「]」。 – Sebyddd

「basic_info」不再可用，您應該使用「public_info」權限。資料來源：http://stackoverflow.com/questions/24762791/facebook-sdk-invalide-scope-basic-info-use-public-profile-user-friends-inst –

對新代碼的Facebook SDK版本4.0及以上

看到這個link

下面

// use facebook SDK 3.8

加入的AppDelegate下面的方法。 m

-(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:. 
}

本身在viewcontroler的follwing代碼.H

#import <UIKit/UIKit.h> 
#import <FacebookSDK/FacebookSDK.h> 
#import <CoreLocation/CoreLocation.h> 

@interface ViewController : UIViewController<FBLoginViewDelegate> 


@property (strong, nonatomic) IBOutlet UILabel *lblUserName; 
@property (strong, nonatomic) IBOutlet UITextField *txtEmailId; 
@property (strong, nonatomic) IBOutlet UIButton *lblCreate; 
@property (strong, nonatomic) IBOutlet FBProfilePictureView *profilePic; 

@property (strong, nonatomic) id<FBGraphUser> loggedInUser; 

- (IBAction)butCreate:(id)sender; 

- (void)showAlert:(NSString *)message 
     result:(id)result 
     error:(NSError *)error; 

@end

//應用下面的代碼到視圖Controller.m或者

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
FBLoginView *loginview=[[FBLoginView alloc]initWithReadPermissions:@[@"email",@"user_likes"]]; 
loginview.frame=CGRectMake(60, 50, 200, 50); 
loginview.delegate=self; 
[loginview sizeToFit]; 
[self.view addSubview:loginview]; 

} 

-(void)loginViewShowingLoggedInUser:(FBLoginView *)loginView 
{ 
self.lblCreate.enabled=YES; 
self.txtEmailId.enabled=YES; 
self.lblUserName.enabled=YES; 


} 

-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user 
{ 
self.lblUserName.text=[NSString stringWithFormat:@"%@",user.name]; 
self.txtEmailId.text=[user objectForKey:@"email"]; 
//self.profilePic.profileID=user.id; 
self.loggedInUser=user; 
} 

-(void)loginViewShowingLoggedOutUser:(FBLoginView *)loginView 
{ 

self.txtEmailId.text=nil; 
self.lblUserName.text=nil; 
self.loggedInUser=nil; 
self.lblCreate.enabled=NO; 

} 
-(void)loginView:(FBLoginView *)loginView handleError:(NSError *)error{ 
    NSLog(@"Show the Error ==%@",error); 
}

夫特1.2 &上述

創建詞典：

class ViewController: UIViewController { 
    var dict : NSDictionary! 
}

獲取數據：

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) 
     } 
    }) 
}

輸出應該是：

{ 
    email = "[email protected]"; 
    "first_name" = Karthi; 
    id = 924483474253864; 
    "last_name" = keyan; 
    name = "karthi keyan"; 
    picture =  { 
     data =   { 
      "is_silhouette" = 0; 
      url = "XXXXXXX"; 
     }; 
    }; 
}

您可以通過使用NSDictionary: NSDictionary<FBGraphUser> *user，你只需要使用objectforkey訪問這樣的價值觀得到這些信息爲你工作。

首先，您必須通過GraphAPI獲取您的應用程序的訪問權限。

用objectandKey創建一個NSMutableDictionary。你的對象將是你正在接受的價值，例如你的名字和你的emailId。

代碼片段：

NSMutableDictionary *params=[[NSMutableDictionary alloc]init]; 

[params setObject:nameStr forKey:@"name"]; 

[params setObject:emailStr forKey:@"email"];

謝謝，它爲我工作 – Anshul

這個目前與最新版本的FB SDK的：

某處設置之前正確設置FB登錄按鈕（假設爲self.facebookLoginButton通過IB初始化）：

self.facebookLoginButton.readPermissions = @[@"public_profile", @"email"]; 
self.facebookLoginButton.delegate = self;

然後在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); 
    }]; 
}

用戶對象的用戶名字段已被刪除，並且在Graph API v2.0中不存在。在API的v2.0中，沒有辦法獲得用戶的FB用戶名。您可以使用應用作用域ID作爲用戶名。

Facebook擺脫了用戶名，因爲用戶名是通過Facebook發送電子郵件的一種方式。例如，給定URL http://www.facebook.com/sebastian.trug 相應的Facebook電子郵件將是[email protected] ，如果通過電子郵件發送，它將直接收到消息（如果消息設置設爲公開），否則將收到其他收件箱。
