我使用的代码
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];
}];
}
从这段代码我需要获取用户名和邮件ID。如果有人知道解决方案，请提前帮助我。

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)

[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:.

Swift 1.2＆amp;上述
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)
}
})
}
输出应为：
{
email = "karthik.saral@gmail.com";
"first_name" = Karthi;
id = 924483474253864;
"last_name" = keyan;
name = "karthi keyan";
picture = {
data = {
"is_silhouette" = 0;
url = "XXXXXXX";
};
};
}

成功登录后发出以下请求，您不会为其读取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 */
}];

您可以使用NSDictionary: NSDictionary<FBGraphUser> *user获取这些信息，
您只需使用objectforkey来访问这些值，例如：
[user objectForKey:@"id"],
[user objectForKey:@"username"],
[user objectForKey:@"email"].
希望它适合你。

目前适用于最新版本的FB SDK：
在正确设置FB登录按钮之前的某处（假设self.facebookLoginButton通过IB初始化）：
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);
}];

User对象的用户名字段已被删除，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app范围ID作为用户名。
Facebook取消了用户名，因为用户名是通过Facebook发送电子邮件的一种方式。 例如，给定网址http://www.facebook.com/sebastian.trug 相应的Facebook电子邮件将是sebastian.trug@facebook.com 如果通过电子邮件发送，将直接接收消息（如果消息设置设置为公共），否则接收到另一个收件箱。来源：https://developers.facebook.com/docs/apps/changelog#v2_0_graph_api
这是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)")
}

使用objectandKey创建NSMutableDictionary。 您的对象将是您正在回收的价值，例如您的姓名和您的emailId。
代码段：
NSMutableDictionary *params=[[NSMutableDictionary alloc]init];
[params setObject:nameStr forKey:@"name"];
[params setObject:emailStr forKey:@"email"];
