swift - 如何在 Swift 中编写一个开关来读取 YouTubePlayerState？

Question

我希望 YouTubePlayer State 更改 View Controller 中的公共(public)变量。我在使用 YTPlayer 代理功能和开关时遇到问题。这是我的变量...

var ytps = String! 

这是 YouTube 状态函数...

func playerView(player: YTPlayerView!, didChangeToState state: YTPlayerState)
    {
        switch (state)
        {
        case YTPlayerState.Ended:
            // handle ended state
            print("Ended")

            break;

        case YTPlayerState.Paused:
            // handle paused state
            print("Paused")

            break;
        default:
            break;
        }
    }

如何获取 YTPlayerState.Ended 或 YTPlayerState.Paused 的状态以将空字符串的值更改为“Ended/Paused”？

Answer 1

我想你可以将 print("Paused") 和 print("Ended") 替换为 ytps = "Paused" 并且ytps =“已结束”。完整示例:

var ytps = String()

func playerView(player: YTPlayerView!, didChangeToState state: YTPlayerState) {
    switch state {
        case YTPlayerState.Ended:
            ytps = "Ended"
            break
        case YTPlayerState.Paused:
            ytps = "Paused"
            break
        default:
            break
    }
}
