应用程序在 IOS 9 时在 AVPlayer TimeControlstatus 崩溃

Question

我的应用程序在 iOS 10 中运行，但在以下行崩溃

ViewModel.IsPlaying = (player.TimeControlStatus == AVPlayerTimeControlStatus.Playing
                || player.TimeControlStatus == AVPlayerTimeControlStatus.WaitingToPlayAtSpecifiedRate);

有错误

-[AVPlayer timeControlStatus]: unrecognized selector sent to instance 0x16fc83f0 An unhandled exception occured.

这发生在ios10以下，请帮忙

Answer 1

答案是 timeControlStatus 只能从 iOS 10 开始使用。

如所述，以下条件似乎非常相似：

(player.timeControlStatus == .playing) == (player.rate != 0.0)

应用程序在 IOS 9 时在 AVPlayer TimeControlstatus 崩溃
