Swift 3.0 Class Note – Video (影片相關)、資料儲存

Presenter : Wei Wei

播放APP內的影片

• 函式庫：AVFoundation, AVKit
• 物件：AVPlayer, AVPlayerViewController
• 設定AVPlayerViewController的屬性
• 和音樂一樣：
  • 丟入影片檔 -> 找到檔案位置 -> 產生url -> 產生AVPlayer
• 和音樂不一樣，無法設定循環播放，介紹用Notifiaction，來設定重新播放：videoPlayer?.currentItem?.seek(to: kCMTimeZero)

  • UserDefaults.standard.synchronize() -> 存檔 step2

  • UserDefaults.standard.integer(forKey: “yeah") -> 取檔

  • 如果怕拼錯Key 用static 變數!!!!!! -> static let myKey = “yeah"
