My name is Nicolás and I am learning how to develop apps for iOS using swift. I need an advice on how to save the user information I retrieve from Facebook Login in order to use it from any view (I was able to use fb login thanks to this tutorial). I tried passing this information through segues but I couldn't achieve this (I recibe this error: Use of unresolved identifier 'userName'). I was thinking maybe something like creating a "global variable" (If they exist in Swift) would be a better practice.
Here is the code of my view controller:
import UIKit
class ViewController: UIViewController, FBLoginViewDelegate {
@IBOutlet var fbLoginView : FBLoginView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.fbLoginView.delegate = self
self.fbLoginView.readPermissions = ["public_profile", "email", "user_friends"]
}
// FACEBOOK DELEGATE METHODS
func loginViewShowingLoggedInUser(loginView : FBLoginView!) {
println("User Logged In")
println("This is where you perform a segue.")
self.performSegueWithIdentifier("gotoview2", sender: self)
}
func loginViewFetchedUserInfo(loginView : FBLoginView!, user: FBGraphUser){
var userName = user.name
}
func loginViewShowingLoggedOutUser(loginView : FBLoginView!) {
println("User Logged Out")
}
func loginView(loginView : FBLoginView!, handleError:NSError) {
println("Error: \(handleError.localizedDescription)")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
if (segue.identifier == "gotoView2") {
let viewController:SecondViewController = segue!.destinationViewController as SecondViewController
viewController.name = userName // !! HERE IS WHERE I RECIBE THE ERROR !!
}
}
}
Thanks you all very much for your help. I am new to this world and the fact that Swift is so new doesn't helps.
Greetings, Nico
