ios - 如何修复错误 : init(boundsSize:requestHandler:)’ is only available on iOS 10. 0

Question

我有这个错误:'init(boundsSize:requestHandler:)' is only available on iOS 10.0 or newer

在我的代码中

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

如何解决？

Answer 1

你可以试试看

if #available(iOS 10.0, *) {
    albumArtwork = MPMediaItemArtwork.init(boundsSize: image.size, requestHandler: { (size) -> UIImage in
        return image
    })
} else {
    // Fallback on earlier versions
    albumArtwork = MPMediaItemArtwork(image: image)
}

如果你想让应用程序与 iOS 10 之前的操作系统版本兼容。否则你可以将部署目标设置为新的 iOS 10。
