Question

注意事项之前，我对编码很陌生，但我已尽力自己寻找答案，如果我问得太愚蠢，我很抱歉D：

我试图制作一个设置页面，您可以关闭整个应用程序的声音/ bgm，到目前为止，我已设法将视图链接到另一个代码。

ViewController.swift

import UIKit
import AVFoundation

class ViewController: UIViewController { 

var ButtonSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("tamborine", ofType: "wav")!)
var audioPlayer = AVAudioPlayer()
var BGMaudioPlayer = AVAudioPlayer()


func playBgMusic(){
    let musicPath = NSBundle.mainBundle().pathForResource("Waiting-in-the-Woods", ofType: "mp3")
    let url = NSURL(fileURLWithPath: musicPath!)
    BGMaudioPlayer = AVAudioPlayer(contentsOfURL: url, error: nil)
    BGMaudioPlayer.numberOfLoops = -1
    //-1為循環播放
    BGMaudioPlayer.volume = 1
    BGMaudioPlayer.prepareToPlay()
    BGMaudioPlayer.play()


}


override func viewDidLoad() {
    super.viewDidLoad()
    audioPlayer = AVAudioPlayer(contentsOfURL: ButtonSound, error: nil)

           //Bgm.play()
}

override func viewWillAppear(animated: Bool) {
      playBgMusic()


    if !BGMaudioPlayer.playing {
        playBgMusic()
    }
}



override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}


@IBAction func quitBtn(sender: UIButton) {
 audioPlayer.play()
    exit(0);
}
@IBAction func Start(sender: UIButton) {
   audioPlayer.play()

}

}

Setting.Swift

import UIKit
import AVFoundation

class Setting: UIViewController {

let mainView = ViewController()

@IBOutlet weak var BGMSwitch: UISwitch!
@IBOutlet weak var SoundsSwitch: UISwitch!

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func soundsswitch(sender: AnyObject) {
    if !SoundsSwitch.on{
        mainView.BGMaudioPlayer.stop()
    }else{
        mainView.BGMaudioPlayer.play()
    }

    }

}

它构建但是当我关闭开关时它崩溃了...... 提前致谢。 d：

要在视图之间发送数据，您可以实现

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if (segue.identifier == "Segue Identifier") {

    }

或

使用委托在视图之间进行通信。

你可以在堆栈溢出时找到很多关于这两个实现的内容。

如何从视图访问属性到另一个视图？
