在applescript中写入/读取单个变量

Question

我刚刚开始使用 xcode 中的 applescript，目前有一个应用程序要求提供文件夹位置，然后创建文件夹结构。

on buttonClick_(sender)
    set theLocation to choose folder with prompt "Where to save your project?"
    tell application "Finder"
        set newFolder to make new folder at theLocation with properties {name:(theTextField's stringValue() as string)}
        set fontsFolder to make new folder at newFolder with properties {name:"fonts"}
        set jpgFolder to make new folder at newFolder with properties {name:"jpg-pdf"}
        set mainFolder to make new folder at newFolder with properties {name:"main"}
        set printFolder to make new folder at mainFolder with properties {name:"• for printer"}
        set refverFolder to make new folder at newFolder with properties {name:"ref_ver"}
        set supportFolder to make new folder at newFolder with properties {name:"support"}
    end tell
    quit
end buttonClick_

现在，我尝试让应用程序采用“theLocation”文件夹别名并保存它，以便下次应用程序启动时，它会自动选择该文件夹作为保存位置，而无需添加它。我理解其中的逻辑，但我不知道如何存储/读取信息。我尝试过有关写入 info.plist 的教程，但没有一个起作用。我是否缺少有关 applescript 如何工作的基本信息？

谢谢

script New_ProjectAppDelegate
property parent : class "NSObject"

property theTextField : missing value
property theLocation : ""

on applicationWillFinishLaunching_(aNotification)
    tell standardUserDefaults() of current application's NSUserDefaults
        registerDefaults_({theLocation:theLocation}) -- register the starting user default key:value items
        set theLocation to objectForKey_("theLocation") as text -- read any previously saved items (which will update the values)
    end tell
end applicationWillFinishLaunching_

on buttonClick_(sender)
    if theLocation is "" then
        set theLocation to choose folder with prompt "Where to save your project?"
        tell standardUserDefaults() of current application's NSUserDefaults
            setObject_forKey_(theLocation, "theLocation") -- update the default items
        end tell
    else
        set theLocation to theLocation as text
        --display dialog theLocation as text
    end if
    tell application "Finder"
        set newFolder to make new folder at theLocation with properties {name:(theTextField's stringValue() as string)}
        set fontsFolder to make new folder at newFolder with properties {name:"fonts"}
        set jpgFolder to make new folder at newFolder with properties {name:"jpg-pdf"}
        set mainFolder to make new folder at newFolder with properties {name:"main"}
        set printFolder to make new folder at mainFolder with properties {name:"• for printer"}
        set refverFolder to make new folder at newFolder with properties {name:"ref_ver"}
        set supportFolder to make new folder at newFolder with properties {name:"support"}
    end tell
    quit
end buttonClick_


on applicationShouldTerminate_(sender)
    tell standardUserDefaults() of current application's NSUserDefaults
        setObject_forKey_(theLocation, "theLocation") -- update the default items
    end tell
    return current application's NSTerminateNow
end applicationShouldTerminate_

结束脚本

属性在 Xcode 脚本中并不持久，但您可以利用 用户默认系统。要使用默认值，您可以在应用程序启动时注册一些初始值，然后从默认值中读取（如果之前已保存，这将覆盖注册的值），并在应用程序退出时保存新值 - 例如：

property theLocation : "" -- this will be the (text) folder path

on applicationWillFinishLaunching_(aNotification)
    tell standardUserDefaults() of current application's NSUserDefaults
        registerDefaults_({theLocation:theLocation}) -- register the starting user default key:value items
        set theLocation to objectForKey_("theLocation") as text -- read any previously saved items (which will update the values)
    end tell
    -- other initialization stuff
end applicationWillFinishLaunching_

on buttonClick_(sender)
    if theLocation is "" then
        set theLocation to choose folder with prompt "Where to save your project?"
        set theLocation to theLocation as text
    end if
    -- display dialog theLocation
    tell application "Finder"
        -- create folder structure
    end tell
    quit
end buttonClick_

on applicationShouldTerminate_(sender)
    tell standardUserDefaults() of current application's NSUserDefaults
        setObject_forKey_(theLocation, "theLocation") -- update the default items
    end tell
    return current application's NSTerminateNow
end applicationShouldTerminate_

您可以在脚本的开头定义一个属性，它允许您即使在脚本退出后也可以存储信息...

property theLocation : null
if theLocation is null then set theLocation to (choose folder with prompt "Where to save your project?"
...

脚本会将别名存储在“theLocation”中以供将来使用。但是，保存或重新编译脚本会将属性重置回其原始值。
