屏幕保護程序啓動時運行蘋果手機

Question

我想在特定時間播放iTunes文件夾播放列表，我自己想出了這個部分。 但事情是，我想在之後將iTunes切換到迷你播放器。所以這裏的代碼

tell application "iTunes" to quit 
delay 5 

tell application "iTunes" 
    reopen 
    activate 
    set song repeat to all 
    set shuffle enabled to true 
    set sound volume to 35 
    delay 5 
    get name of AirPlay devices 
    set selected of AirPlay device "Airport Express" to true 
    play playlist "mom's music" 
end tell 

delay 20 

-- here comes the part I don't get 

tell application "System Events" 
    tell process "iTunes" 
     set frontmost to true 
     if title of window 1 is "미니 플레이어" then 
      click menu item 9 of menu 9 of menu bar 1 
      delay 5 
      click menu item 9 of menu 9 of menu bar 1 
     else 
      click menu item 9 of menu 9 of menu bar 1 
     end if 
    end tell 
end tell 

沒關係的上半部分。請看「系統事件」部分。

當屏幕保護程序沒有運行時，它的工作方式與預期的一樣，但在屏幕保護程序運行時沒有運行，但我無法弄清楚我錯過了什麼。

那麼，我還沒有意識到在屏幕保護程序下運行applescript有另一個限制嗎？任何建議，將不勝感激。謝謝。

我來到注意到當我按下「窗口」菜單項，iTunes（主要的）窗口中消失。這是否意味着我必須超越屏幕保護程序才能通過applescript對窗口執行任何操作？

Answer 1

看來當屏幕保護程序正在運行時，腳本仍然會運行但不處理某些事件。解決方法是在運行任何依賴於UI腳本的代碼之前停止屏幕保護程序。

例子：

tell application "System Events" 
    key code 53 -- # Esc key. 
    delay 1 - # Adjust as necessary, the screen saver needs to have stopped before continuing. 
    tell process "iTunes" 
     set frontmost to true 
     if title of window 1 is "미니 플레이어" then 
      click menu item 9 of menu 9 of menu bar 1 
      delay 5 
      click menu item 9 of menu 9 of menu bar 1 
     else 
      click menu item 9 of menu 9 of menu bar 1 
     end if 
    end tell 
end tell

試試這個版本

try 
    tell application id "com.apple.ScreenSaver.Engine" to quit 
end try 

tell application "System Events" 
    tell process "iTunes" 
     set frontmost to true 
     if title of window 1 is "미니 플레이어" then 
      click menu item 9 of menu 9 of menu bar 1 
      delay 5 
      click menu item 9 of menu 9 of menu bar 1 
     else 
      click menu item 9 of menu 9 of menu bar 1 
     end if 
    end tell 
end tell
