从iOS的Facebook获取用户的个人信息

问题描述：

我对Objective-C和iPhone开发环境颇为陌生。从iOS的Facebook获取用户的个人信息

我在我的应用程序中实现Facebook登录以获取用户的姓名，电子邮件和个人资料图片。我已成功实施登录部分并已收到人员的姓名和用户标识。

现在我想从Facebook获取用户的电子邮件和个人资料图片，但我没有任何想法如何得到它。我使用的是Facebook IOS SDK v4.0。

如何从Facebook获取用户的个人资料图片和电子邮件ID时，我有用户ID？

@Shruti没关系我已经尝试过实现这个链接，但我只有名字和姓氏，没有提供获得电子邮件ID – 2015-04-06 12:27:34

要获取用户电子邮件ID，您必须在登录时询问电子邮件地址的权限。

FBSDKLoginButton *loginView = [[FBSDKLoginButton alloc] init]; 
loginView.readPermissions = @[@"email"]; 
loginView.frame = CGRectMake(100, 150, 100, 40); 
[self.view addSubview:loginView];

您可以使用GraphPath在New SDK中获取用户电子邮件ID。

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil] 
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 

      if (!error) { 
       NSLog(@"fetched user:%@ and Email : %@", result,result[@"email"]); 
     } 
     }]; 
    }

结果将让你所有的用户详细信息和结果[@“电子邮件”对于登录的用户会得到你的电子邮件。

获得简介图片您可以使用

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=normal",result[@"id"]]]; 
NSData *data = [NSData dataWithContentsOfURL:url]; 
_imageView.image = [UIImage imageWithData:data];

或u还可以使用FBSDKProfilePictureView通过将用户个人资料ID来获得的个人资料图片：

FBSDKProfilePictureView *profilePictureview = [[FBSDKProfilePictureView alloc]initWithFrame:_imageView.frame]; 
[profilePictureview setProfileID:result[@"id"]]; 
[self.view addSubview:profilePictureview];

参考：https://developers.facebook.com/docs/facebook-login/ios/v2.3#profile_picture_view

或你也可以通过传递参数

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" 
              parameters:@{@"fields": @"picture, email"}] 
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
      if (!error) { 
       NSString *pictureURL = [NSString stringWithFormat:@"%@",[result objectForKey:@"picture"]]; 

       NSLog(@"email is %@", [result objectForKey:@"email"]); 

       NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:pictureURL]]; 
       _imageView.image = [UIImage imageWithData:data]; 

      } 
      else{ 
       NSLog(@"%@", [error localizedDescription]); 
      } 
     }];

嗨dheeraj我试过这个，但我在我的电子邮件中为空。 – 2015-04-07 09:10:52

您在登录时必须要求电子邮件许可。 – 2015-04-07 09:11:37

我已经完成 FBSDKLoginButton * loginButton = [[FBSDKLoginButton alloc] init]; loginButton.center = self.view.center; [self.view addSubview：loginButton]; self.loginButton.readPermissions = @ [@“public_profile”，@“email”]; 在我的viewDidLoad – 2015-04-07 09:13:02

对不起，这是凌乱的答案，这是我的第一个答案。您可以使用FBSDK Graph请求获取用户的所有配置文件信息和FBSDKProfilePictureView类以轻松获取用户的配置文件图片。此代码用于手动Facebook登录UI。

首先，你必须把这段代码登录过程开始：

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init]; 

[login logInWithReadPermissions:@[@"public_profile", @"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { 

    if (error) 
    { 

    // There is an error here. 

    } 
    else 
    { 
     if(result.token) // This means if There is current access token. 
     {  
      // Token created successfully and you are ready to get profile info 
      [self getFacebookProfileInfo]; 
     }   
    } 
}];

而如果登录全成，实现这个方法来获取用户的公众形象;

-(void)getFacebookProfileInfos { 

FBSDKGraphRequest *requestMe = [[FBSDKGraphRequest alloc]initWithGraphPath:@"me" parameters:nil]; 

FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init]; 

[connection addRequest:requestMe completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 

     if(result) 
     {    
     if ([result objectForKey:@"email"]) { 

      NSLog(@"Email: %@",[result objectForKey:@"email"]); 

     } 
     if ([result objectForKey:@"first_name"]) { 

      NSLog(@"First Name : %@",[result objectForKey:@"first_name"]); 

     } 
     if ([result objectForKey:@"id"]) { 

      NSLog(@"User id : %@",[result objectForKey:@"id"]); 

     } 

     } 

}]; 

[connection start];

获取用户的个人资料图片当前登录：

FBSDKProfilePictureView *pictureView=[[FBSDKProfilePictureView alloc]init]; 

[pictureView setProfileID:@"user_id"]; 

[pictureView setPictureMode:FBSDKProfilePictureModeSquare]; 

[self.view addSubview:pictureView];

您必须添加清爽码到您的viewDidLoad方法：

[FBSDKProfile enableUpdatesOnAccessTokenChange:YES];

facebookLoginButtonTouched没有被调用 – 2015-04-07 04:58:21

我在我的项目中使用自定义的Facebook登录按钮。所以“facebookLoginButtonTouched”是我的自定义登录按钮的“触及内部”方法。我正在编辑我的答案。 – 2015-04-07 08:55:47
