确定QuickTime何时使用AppleScript停止录制

Question

我正在使用以下AppleScript来确定用户何时点击任务栏中的停止录制按钮：

tell application "QuickTime Player"
    tell document 1
        activate
        new screen recording
        delay 1
        tell application "System Events" to key code 49
        delay 2
        repeat until (new screen recording) is false
        end repeat
    end tell
end tell

虽然脚本不断重新启动QuickTime。

您可以将new screen recording命令的结果放入变量。

使用存在命令检查此文档

tell application "QuickTime Player"
    activate
    set tdoc to new screen recording --> document "Screen Recording"
    delay 1
    tell application "System Events" to key code 49
    delay 2
    repeat while exists tdoc
        delay 1
    end repeat
    -- the recording is stopped
    tell front document
        -- do something with the front document ("Untitled")
    end tell
end tell
