【中文标题】如何获取 Facebook SDK 的用户名和电子邮件 ID？【英文标题】：How to get user name and email id for Facebook SDK? 【发布时间】：2014-02-25 09:54:49 【问题描述】：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];
];
我需要从这段代码中获取用户名和邮件 ID。如果有人知道解决方案，请帮助我提前谢谢。

[Facebook-ios-SDK 4.0]How to get user email address from FBSDKProfile的可能重复 【参考方案1】： if ([FBSDKAccessToken currentAccessToken])
[[[FBSDKGraphRequest alloc] initWithGraphpath:@"me" parameters:@@"fields": @"email,name,first_name"]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
if (!error)

【参考方案2】：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,

NSLog(@"accesstoken %@",[NSString stringWithFormat:@"%@",session.accessTokenData]);
NSLog(@"user id %@",user.id);
NSLog(@"Email %@",[user objectForKey:@"email"]);
NSLog(@"User Name %@",user.username);
];
];
【讨论】：
“basic_info”不再可用，您应该使用“public_info”权限。来源：***.com/questions/24762791/…【参考方案3】：对于新代码 facebook SDK ver 4.0 及更高版本
看到这个link
下面
// use facebook SDK 3.8
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:.
查看 viewcontroler .h 中的以下代码
#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
// 将以下代码应用到您的视图控制器.m
- (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);
Swift 1.2 及以上版本
创建字典：
class ViewController: UIViewController
var dict : NSDictionary!
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)
)
输出应该是：
email = "karthik.saral@gmail.com";
"first_name" = Karthi;
id = 924483474253864;
"last_name" = keyan;
name = "karthi keyan";
picture =
data =
"is_silhouette" = 0;
url = "XXXXXXX";
;
;
【讨论】：
只是我还是这个答案是 Objective-C 和 Swift 的奇怪组合？【参考方案4】：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 */
];
点击此链接：https://developers.facebook.com/docs/graph-api/reference/user
【讨论】：
【参考方案5】：您可以使用NSDictionary: NSDictionary<FBGraphUser> *user获取这些信息，
您只需要使用objectforkey 来访问这些值，例如：
[user objectForKey:@"id"],
[user objectForKey:@"username"],
[user objectForKey:@"email"].
希望它对你有用。
【讨论】：
【参考方案6】：这目前适用于最新版本的 FB SDK：
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;
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);
];
这里是有帮助的参考页面：https://developers.facebook.com/docs/graph-api/reference/user
【讨论】：
【参考方案7】：User 对象的用户名字段已被移除，并且在 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 删除了用户名，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 电子邮件是 sebastian.trug@facebook.com 如果通过电子邮件发送，将直接接收到消息（如果消息设置设置为公开），否则将接收到另一个收件箱。

这里是 swift 3.0 的代码
let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me",
parameters: ["fields":"first_name,email, picture.type(large)"])
graphRequest.start(completionHandler: (connection, result,
error) -> Void in
if ((error) != nil)
print("Error: \(error)")
else
let data:[String:AnyObject] = result as! [String : AnyObject]
print(data)
)

【参考方案8】：[FBRequestConnection startWithGraphPath:@"/me"
parameters:nil
HTTPMethod:@"GET"
completionHandler:^(
FBRequestConnection *connection,
NSDictionary *result,
NSError *error
)
/* handle the result */
_fbId = [result objectForKey:@"id"];
_fbName = [result objectForKey:@"name"];
_fbEmail = [result objectForKey:@"email"];
NSLog(@"%@",_fbId);
NSLog(@"%@",_fbName);
NSLog(@"%@",_fbEmail);
];
【讨论】：
【参考方案9】：使用此代码：
FBSession *session = [[FBSession alloc] initWithPermissions:@[@"public_profile"]];
[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(@"%@", user);
[[[UIAlertView alloc] initWithTitle:@"welcome"
message:[NSString stringWithFormat:@"%@\n%@\n%@\n%@\n%@\n%@",
user[@"name"],
user[@"gender"],
user[@"id"],
user[@"link"],
user[@"email"],
user[@"timezone"]]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil]
show];
];
];

print(fbDetails)
else

【参考方案11】：Xcode 8.2.1 和 Objective-C
杀掉应用后在任何地方获取登录信息
FBRequest *friendRequest = [FBRequest requestForGraphPath:@"me/?fields=name,picture,birthday,email,location"];
[friendRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error)
if(error == nil)
UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Facebook" message:@"Success in fetching Facebook information." delegate:self cancelButtonTitle:@"OK"otherButtonTitles:nil, nil];
[alert show];
else
UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Facebook" message:@"Problem in fetching Facebook Information. Try Later!" delegate:self cancelButtonTitle:@"OK"otherButtonTitles:nil, nil];
[alert show];
];
【讨论】：
【参考方案12】：-
首先您必须通过 GraphAPI 获得您的应用程序的访问权限。
使用 objectandKey 创建一个 NSMutableDictionary。 您的对象将是您收到的值，例如您的姓名和 emailId。
代码sn-p：
NSMutableDictionary *params=[[NSMutableDictionary alloc]init];
[params setObject:nameStr forKey:@"name"];
[params setObject:emailStr forKey:@"email"];
