How can I stop the videobackground when I move to another viewcontroller?
because when I move to another viewcontroller, the video and background music continue to be played, and when I go back to the main page two videos overlap. so I would like the video and the music to stop when I move to another viewcontroller, such as when I move in the viewcontroller for the sign up
import UIKit
import SwiftVideoBackground
import Firebase
import FirebaseAuth
class ViewController: UIViewController {
private let videoBackground = VideoBackground()
#IBOutlet weak var usernameField: UITextField!
#IBOutlet weak var passwordField: UITextField!
#IBOutlet weak var mute_img: UIImageView!
#IBOutlet private var muteSwitch: UISwitch!
#IBAction func `switch`(_ sender: UISwitch) {
if (sender.isOn == true)
{
mute_img.isHidden = false
videoBackground.isMuted = true
}
else
{
mute_img.isHidden = true
videoBackground.isMuted = false
}
let shouldMute = sender.isOn
videoBackground.isMuted = shouldMute
UserDefaults.standard.set(shouldMute, forKey:"isMuted")
}
override func viewDidLoad() {
super.viewDidLoad()
let userDefaults = UserDefaults.standard
let shouldMute = userDefaults.bool(forKey: "isMuted")
videoBackground.play(view: view, videoName: "intro", videoType:
"mp4", isMuted: shouldMute, willLoopVideo : true)
muteSwitch.isOn = shouldMute
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view.endEditing(true)
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
if textField == usernameField {
passwordField.becomeFirstResponder()
} else if textField == passwordField {
textField.resignFirstResponder()
}
return true
}

}

Follow the steps:
1) Make an IBOutlet for the switch
#IBOutlet private var muteSwitch: UISwitch!
Don't forget to connect it to the switch in the storyboard.
2) Read the saved value from UserDefaults ( in viewDidLoad ):
override
func viewDidLoad() {
super.viewDidLoad()
let userDefaults = UserDefaults.standard
let shouldMute = userDefaults.bool(forKey: "isMuted")
videoBackground.play(view: view, videoName: "intro", videoType: "mp4", isMuted: shouldMute, alpha : 0.25, willLoopVideo : true)
muteSwitch.isOn = shouldMute
}
3) Save the switch value to UserDefaults ( in #IBAction func `switch`...) :
#IBAction func `switch`(_ sender: UISwitch) {
let shouldMute = sender.isOn
videoBackground.isMuted = shouldMute
UserDefaults.standard.set(shouldMute, forKey:"isMuted")
}

}
- (IBAction)saveSwitchState:(id)sender

if ([self.bluetoothSwitch isOn])
[defaults setBool:YES forKey:#"SwitchState"];
else
[defaults setBool:NO forKey:#"SwitchState"];
}

Swift Version
import UIKit

override func viewDidLoad() {
super.viewDidLoad()
let userDefaults = UserDefaults.standard
if userDefaults.value(forKey: "isMuted") != nil{
let object = userDefaults.value(forKey: "isMuted") as? NSNumber
yourSwitch.isOn = (object?.boolValue)!
}
}
#IBAction func switchChanged(sender: UISwitch) {
let uDefault = UserDefaults.standard
if sender.isOn {
uDefault.setValue(NSNumber(value: true), forKey:"isMuted")
}
else {
uDefault.setValue(NSNumber(value: false), forKey:"isMuted")
}
}
