ios - 播放音频时设置自定义元数据(控制中心、锁屏...)

Question

总结

我目前正在尝试为每次播放音频时设置一个应用范围内的默认元数据。目前，只有音频流的 URL 显示在控制中心和锁屏上。我正在尝试自己的自定义值；但是，我无法让它工作。可能值得注意的是，音频是通过 UIWebView 播放的。

(下续截图)

ViewController.swift

import UIKit
import AVFoundation
import MediaPlayer

class ViewController: UIViewController, UIWebViewDelegate, UIScrollViewDelegate {

    var mPlayer: MPMediaItem!

    override func viewDidLoad() {
        super.viewDidLoad()

        let image = UIImage(named: "Artwork")!
        let artwork = MPMediaItemArtwork.init(boundsSize: image.size, requestHandler: { (size) -> UIImage in
                return image
            })

        let nowPlaying: NSDictionary = [MPMediaItemPropertyTitle: "Song",
                                        MPMediaItemPropertyArtist: "Artist",
                                        MPMediaItemPropertyArtwork: artwork]

        MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlaying as? [String : Any]
    }
}

您必须使用其初始化程序初始化 MPMediaItemArtwork

let image = UIImage(named: "Artwork")!
let artwork = MPMediaItemArtwork.init(boundsSize: image.size, requestHandler: { (size) -> UIImage in
    return image
})
