import UIKit 

class signUpPage: UIViewController {

override func viewDidLoad() { 
    self.viewDidLoad() 
} 
override func didReceiveMemoryWarning() { 
    self.didReceiveMemoryWarning() 
} 

@IBAction func registerAction(sender: AnyObject) { 
    let email = self.emailTextField.text 
    let pass = self.passTextField.text 
    if (email != "" && pass != ""){ 

     firebase_ref.createUser(email, password: pass, withValueCompletionBlock: { (error, results) in 
      if (error == nil){ 
       firebase_ref.authUser(email, password: pass, withCompletionBlock: { (error, authData) in 
        if (error == nil){ 
         NSUserDefaults.standardUserDefaults().setValue(authData.uid, forKey: "uid") 
         print("Account created Successfully ") 
         self.dismissViewControllerAnimated(true, completion: nil) 
        }else{ 
         print(error.localizedDescription) 
        } 
       }) 
      }else{ 
       print(error.localizedDescription) 
      } 
     }) 


    }else{ 
     let alert = UIAlertController(title: "Error", message: "Enter an email and password", preferredStyle: .Alert) 
     let okAction = UIAlertAction(title: "ok", style: .Default, handler: nil) 
     alert.addAction(okAction) 
     self.presentViewController(alert, animated: true, completion: nil) 
    } 
} 

@IBAction func cancleAction(sender: AnyObject) { 

    self.dismissViewControllerAnimated(true, completion: nil) 
}

} 在此先感謝您的幫助:)
