如何使用AppleScript在iTunes中設置播放列表的曲目？

Question

我正在嘗試使用AppleScript設置用戶播放列表的曲目。我不希望添加曲目，我希望他們替換當前曲目。在我這樣做之前，我需要通過它們的持久ID來查找軌跡，這些軌跡工作正常，但設置軌跡的語句不起作用。代碼片段如下：

  set fixed indexing to true 
     set myPlaylist to the first item of (every user playlist whose persistent ID is "5C768EFF306E3366") 

     set tracksPIDs to {"66EB935073027EDD", "B6807694FEDD76B4"} 
     set resolvedTracks to {} 

     --resolve the tracks 
     repeat with trackPID in tracksPIDs 
      set myTrack to the first item of (every track whose persistent ID is equal to trackPID) 
      set end of resolvedTracks to myTrack 
     end repeat 

     set (the tracks of my myPlaylist) to duplicate of (resolvedTracks) 

此外，如何從播放列表中刪除所有曲目（即其設置爲空列表）？

Answer 1

要做你想做的事，你需要做兩個步驟，首先從播放列表中刪除現有的曲目，然後添加你想要在播放列表中的曲目。第一步將是這樣的：

delete every track of myPlaylist 

然後加入會是什麼樣子：

duplicate resolvedTracks to myPlaylist
