swift - dismissing mail view controller from Sprite Kit - swift

Question

I am trying to add a send email button to a Sprite Kit game. I can get the email dialog to show up. But if I hit cancel, the app will crash or do nothing. If I hit send, the email will send, but the dialog stays. I cannot get the mailComposeController function to fire...please help!
Code:
import Foundation
import UIKit
import MessageUI
class MailViewController: UIViewController, MFMailComposeViewControllerDelegate {
let systemVersion = UIDevice.currentDevice().systemVersion
let devicemodel = UIDevice.currentDevice().model
let appVersion = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String
let appBuild = NSBundle.mainBundle().infoDictionary?["CFBundleVersion"] as! String
let myrootview2 = UIApplication.sharedApplication().keyWindow?.rootViewController
let mailComposerVC = MFMailComposeViewController()
override func viewDidLoad() {
super.viewDidLoad()
}
func sendEmailButtonTapped(sender: AnyObject) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.view.window?.rootViewController = mailComposerVC
print("This is the rootview2: \(myrootview2)")
myrootview2!.presentViewController(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func configuredMailComposeViewController() -> MFMailComposeViewController {
var msgbody: String
mailComposerVC.mailComposeDelegate = self
msgbody = "\n\nDevice: \(devicemodel)\niOS Version: \(systemVersion)\nApp Version: \(appVersion)\nApp Build Number: \(appBuild)\n"
mailComposerVC.setToRecipients(["test1#test.com"])
mailComposerVC.setSubject("test subject")
mailComposerVC.setMessageBody(msgbody, isHTML: false)
//print(mailComposerVC)
return mailComposerVC
}
func showSendMailErrorAlert() {
let sendMailErrorAlert = UIAlertView(title: "Could Not Send Email", message: "Your device could not send e-mail. Please check e-mail configuration and try again.", delegate: self, cancelButtonTitle: "OK")
sendMailErrorAlert.show()
}
// THIS DOESN'T GET CALLED WHEN SENDING OR CANCELLING EMAIL!
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
let test1 = result.rawValue
print(test1)
print(controller)
print(self)
print(myrootview2)
}

Answer 1

The issue is you are making the mailVC as the root view, you have to present it on your view like given below
#IBAction func sendEmailButtonTapped(sender: AnyObject) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.presentViewController(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
 func mailComposeController(controller: MFMailComposeViewController!, didFinishWithResult result: MFMailComposeResult, error: NSError!) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
