Question

我正在尝试使用applescript在OS X中设置桌面图片。这段代码在10.6-10.8中有效，但在小牛队（10.9）中被打破了。

tell application "System Events"
    tell current desktop
        set picture to POSIX file "/development/desk/x.jpg"
    end tell
end tell

我知道他们改变了支持多个显示器的方式，但我不确定可能会破坏这个。

Answer 1

感谢this github project这有效。也许10.9中不存在默认桌面的想法？

    tell application "System Events"
        set theDesktops to a reference to every desktop
        repeat with x from 1 to (count theDesktops)
            set picture of item x of the theDesktops to "/development/desk/x.jpg"
        end repeat
    end tell

Answer 2

HFS路径（“disk：item：subitem：subsubitem：...：item”）不起作用。如果您打开系统首选项，将会出现以下错误 - ＆gt;桌面和桌面屏幕保护程序

24/10/13 6：31：47.340 pm系统偏好设置[3085]：DesktopPref 错误： kDesktopPictureValueImagePath 的加载失败

tell application "System Events"
    tell current desktop
--not working
        set picture to "mavricks:Library:Desktop Pictures:Abstract.jpg" 
        get properties
--{display name:"iMac", change interval:1.0, id:69671552, random order:false, picture rotation:0, pictures folder:"/Library/Desktop Pictures/", picture:"mavericks:Library:Desktop Pictures:Abstract.jpg", translucent menu bar:true, class:desktop}
    end tell
end tell

POSIX路径（/ item / subitem / subsubitem /.../ item）工作正常

tell application "System Events"
    tell current desktop
        set picture to "/Library/Desktop Pictures/Abstract.jpg"
        get properties
--{display name:"iMac", change interval:1.0, id:69671552, random order:false, picture rotation:0, pictures folder:"/Library/Desktop Pictures/", picture:"/Library/Desktop Pictures/Abstract.jpg", translucent menu bar:true, class:desktop}
    end tell
end tell

Answer 3

我赞成Parag，但我撤回了我的评论。在Mavericks中设置/记住自定义壁纸时似乎存在错误/不一致，可能是因为此信息存储在SQLite DB文件中~/Application Support/Dock/desktoppicture.db - 请参阅reference。

例如，在桌面＆amp;屏幕保护程序首选项窗格，从外部高清设置自定义墙纸以在登录时随机更改，在重新启动时始终重置为默认的 Mavericks Beach Wave 壁纸。幸运的是，我发现了为什么会发生这种情况并且solution。

关于Parag的回答，请采用以下脚本：

tell application "System Events"
    tell current desktop
        if picture rotation ≠ 2 then -- same value as line below
            set picture rotation to 2 -- 0=off | 1=interval | 2=login | 3=sleep
        end if
        if random order = false then
            set random order to true
        end if
        -- set pictures folder to "Volumes:MEDIA:Pictures:Wallpapers" -- doesn't work
        set pictures folder to "/Volumes/MEDIA/Pictures/Wallpapers" -- works
        -- set change interval to 86400 -- value in seconds | uncomment line if picture rotation is set to interval
    end tell
end tell

嗯，它不起作用。它不会返回任何错误，但壁纸根本不会改变。如果我将其更改为POSIX路径/Volumes/MEDIA/Pictures/Wallpapers，那么它可以正常工作。

另一方面，如果你在AppleScript代码中指定POSIX path of file，那么通过jimmy解决原始问题并与Parag相矛盾，下面的脚本（使用HFS路径）似乎在Mavericks 10.9.5中正常工作：

tell application "System Events"
    set picture of current desktop to POSIX path of file "development:desk:x.jpg"
end tell

从os x mavericks中的applescript设置桌面照片（10.9）
