ios - 在 MPMediaItemPropertyArtwork 中显示的 URL

Question

所以我想显示来自 URL 的图像。

我知道我首先需要将其编码为友好的 URL -

.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!

例如

if var strUrl = nowplaying.data.first?.track.imageurl {
  strUrl = strUrl.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
 }

但是我如何才能将它放入 MPMediaItemPropertyArtwork。

我尝试了很多与使用第 3 部分 kingfisher 插件不同的事情 - 但没有成功。

如果有人能告诉我如何得到下面的图像来显示那会很棒

您需要设置 MPRemoteCommandCenter 及其 nowPlayingInfo:

    func setupNowPlayingInfo(with artwork: MPMediaItemArtwork) {
        nowPlayingInfo = [
            MPMediaItemPropertyTitle: "Some name",
            MPMediaItemPropertyArtist: "Some name",
            MPMediaItemPropertyArtwork: artwork,
            MPMediaItemPropertyPlaybackDuration: CMTimeGetSeconds(currentItem.duration)
            MPNowPlayingInfoPropertyPlaybackRate: 1,
            MPNowPlayingInfoPropertyElapsedPlaybackTime: CMTimeGetSeconds(currentItem.currentTime())
        ]
    }

   func getData(from url: URL, completion: @escaping (UIImage?) -> Void) {
        URLSession.shared.dataTask(with: url, completionHandler: {(data, response, error) in
            if let data = data {
                completion(UIImage(data:data))
            }
        })
            .resume()
    }

    func getArtBoard() {
        guard let url = URL(string: "http://covers.drn1.com.au/az_B101753_Wish%20You%20Were%20Here_Brain%20Purist.jpg") else { return }
        getData(from: url) { [weak self] image in
            guard let self = self,
                let downloadedImage = image else {
                    return
            }
            let artwork = MPMediaItemArtwork.init(boundsSize: downloadedImage.size, requestHandler: { _ -> UIImage in
                return downloadedImage
            })
            self.setupNowPlayingInfo(with: artwork)
        }
    }
