Swift 音频传递给另一个 ViewController

Question

override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
    if segue.identifier == "stopRecording" {             
        let playSoundsVC = segue.destination as! PlaySoundsViewController          
        let recordedAudioURL = sender as! URL           
        playSoundsVC.receivedAudio = recordedAudioURL               
    }
}

问题是我的 Xcode 生成错误

Value of type 'PlaySoundsViewController' has no member 'receivedAudio'

Answer 1

要使其正常工作，目标 VC 应如下所示

class PlaySoundsViewController:UIViewController {

    var receivedAudio:URL?

    .....
 }
