Applescript 通过属性的字符串名称获取属性的值

问题描述

在 AppleScript 中.假设我有一个名为 Title 的属性的记录.

In AppleScript. Let's say I have a record with a property called Title.

假设我为文本标题"设置了一个变量；我可以使用该变量来获取属性 Title 的值吗?基本上，有没有办法做这样的事情:

Let's say I set a variable to the text "Title"; can I use that variable to get the value of the property Title? Basically, is there any way to do something like this:

set result to property named "Title" of myRecord

代替:

set result to Title of myRecord

推荐答案

我找到了答案.我也意识到我没有问正确的问题.我试图获取的值来自属性列表项.

I found the answer. I also realize I didn't ask the correct question. The value I'm trying to obtain is from a property list item.

这是我学到的东西，以及如何做到这一点:

Here's what I learned, and how to accomplish this:

use framework "Foundation"

set _plist to ...

set _objcPlist to GetAppleScriptObjectAsObjcObject(_plist)

set _value to GetObjcPropertyValueByName("MyProperty", item 1 of _objcPlist)

on GetAppleScriptObjectAsObjcObject(asObject)
    set a to current application
    set cClass to class of asObject

    if (cClass is record) then
        return a's NSDictionary's dictionaryWithDictionary:asObject
    else if (cClass is list) then
        return a's NSArray's arrayWithArray:asObject
    else
        error "Unexpected Class Type"
    end if
end GetAppleScriptObjectAsObjcObject

on GetObjcPropertyValueByName(propertyName, objcItem)
    return (objcItem's valueForKey:propertyName) as text
end GetObjcPropertyValueByName
