Unable to use FBSDKGraphRequest with Parse login - ios

Question

I'm using Parse to login with facebook on my app.
This is my code :
//set permissions required
let permissionsArray = ["user_about_me"]
//log in
PFFacebookUtils.logInWithPermissions(permissionsArray, block: { (pUser, pError) -> Void in
//if user is correctly loggin
if pUser != nil && pError == nil{
//request facebook for more informations
var request = FBSDKGraphRequest(graphPath: "me", parameters: nil)
request.startWithCompletionHandler({ (connection, result, error) -> Void in
NSLog("\(error)")
})
}
})
I am correctly log in with parse, but when i'am asking for my informations, have always have this message :
com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={
body = {
error = {
code = 2500;
message = "An active access token must be used to query information about the current user.";
type = OAuthException;
};
};
code = 400;
}}

I have used Facebook SDK for login, i make a Parse login with returned token and i can get my user's informations after that.
I have solved my issue with this code :
FBSDKLoginManager().logInWithReadPermissions(["user_about_me"], handler: { (result, error) -> Void in
if let resultLogin : FBSDKLoginManagerLoginResult = result as? FBSDKLoginManagerLoginResult{
//if no error
if error == nil
&& resultLogin.grantedPermissions.contains("user_about_me"){
var accessToken = FBSDKAccessToken.currentAccessToken().tokenString
var expiration = FBSDKAccessToken.currentAccessToken().expirationDate
var facebookID = FBSDKAccessToken.currentAccessToken().userID
PFFacebookUtils.logInWithFacebookId(facebookID, accessToken: accessToken, expirationDate: expiration, block: { (pUser, pError) -> Void in
//if user is correctly loggin
if pUser != nil && pError == nil{
//request facebook for more informations
var request = FBSDKGraphRequest(graphPath: "me", parameters: nil)
request.startWithCompletionHandler({ (connection, result, error) -> Void in
NSLog("\(error)")
})
}
})
}
}
})
