Button triggering video to open and play - ios

Question

I am very new to coding and have no experience.
I have found a way to make a video play but it autoplays / autopens. I need the video to only open and play when a button is pressed. Please can someone help me tweak my code to do this.
This is my current code:
import UIKit
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
var playerviewcontroller = AVPlayerViewController()
var playerview = AVPlayer ()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func viewDidAppear(animated: Bool) {
var fileURL = NSURL(fileURLWithPath:"/Users/MorganEvans/Documents/Apps/Warm Up/Video View/Video View/ViewController.swift")
playerview = AVPlayer(URL: fileURL)
playerviewcontroller.player = playerview
self.presentViewController(playerviewcontroller, animated: true){
self.playerviewcontroller.player?.play()
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 1

Try this:
#IBAction func playMusic(sender: AnyObject) {
var fileURL = NSURL(fileURLWithPath:"/Users/MorganEvans/Documents/Apps/Warm Up/Video View/Video View/ViewController.swift")
playerview = AVPlayer(URL: fileURL)
playerviewcontroller.player = playerview
self.presentViewController(playerviewcontroller, animated: true){
self.playerviewcontroller.player?.play()
}
}
You can simply put it anywhere in your ViewController, as long as it is not inside another function.
Then connect it with a button in your storyboard:

this is how a button would set up to look, this example is pulling a movie from firebase but other than that this is how it would look
#IBAction func playV(sender: UIButton) {
let amovieUrl:NSURL? = NSURL(string: "https://firebasestorage.googleapis.com/v0/b/messenger-test-d225b.appspot.com/o/test%2FTestVideo.mov?alt=media&token=bd4ccba3-b446-43bc-809e-b1152aa3c2ff")
if let aurl = amovieUrl {
self.avPlayer = AVPlayer(url: aurl as URL)
self.avPlayerViewController.player = self.avPlayer
self.present(self.avPlayerViewController, animated: true) { () -> Void in
self.avPlayerViewController.player?.play()
}
}
}

Answer 3

Create an Action Connection as explained here.
Move that code in viewDidAppear to the action you created in step 1.
Profit.
Also, you don't need those default implementation for viewDidLoad and didReceiveMemoryWarning:
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
var playerviewcontroller = AVPlayerViewController()
var playerview = AVPlayer ()
#IBAction func yourActionForButton(sender: UIButton) {
// Your code.
}
