“POSIX 文件"适用于 Applescript 编辑器，而不适用于 XCode [英] "POSIX file" works in Applescript Editor, not in XCode

问题描述

试试这个:

1. 创建一个新的 XCode4 Applescript 项目.在委托中，粘贴以下代码:

   on doIt_(sender)将 goodHFSLoc 设置为(桌面文件夹的路径)将 test1 设置为(goodHFSLoc 的 POSIX 路径)记录test1:"&test1将 JSPath 设置为/Users/dave/Desktop/MakeTSLabels.js"将 jsHFSFile 设置为(POSIX 文件 theJSPath)将 test2 设置为(jsHFSFile 的 POSIX 路径)结束做它_

2. 将此方法与 UI 窗口中的按钮挂钩.

3. 运行程序

4. 点击按钮，你应该得到这个错误:

   无法获取类NSObject"的POSIX路径.

5. 将相同的代码(减去on"和end"行)放入 AppleScript 编辑器，它运行良好.

显然，ApplescriptObjC 中的POSIX 文件"没有将文件对象作为语言规范需要.相反，它生成了一个 NSObject.

我需要有一个 applescript 文件说明符来提供给 Adob​​e Illustrator 的 do javascript 命令，并且我需要使用 NSBundle 的函数来获取 javascript 文件，该文件打包在我的应用程序包中.

我做错了吗?

解决方案

您将在 Finder 或 System Events tell 语句中看到相同的行为.ASObjC 的解决方案是一样的——你需要将它用作强制:

set jsHFSFile to (theJSPath as POSIX file)

Try this:

1. Make a new XCode4 Applescript project. In the delegate, paste this code:

   on doIt_(sender)
       set goodHFSLoc to (path to desktop folder)
       set test1 to (POSIX path of goodHFSLoc)
       log "test1:"&test1
       set theJSPath to "/Users/dave/Desktop/MakeTSLabels.js"
       set jsHFSFile to (POSIX file theJSPath)
       set test2 to (POSIX path of jsHFSFile)
   end doIt_
   

2. Hook this method up to a button in the UI window.

3. Run the program

4. Click the button, and you should get this error:

   Can’t get POSIX path of class "NSObject".
   

5. Put the same code (minus the "on" and "end" lines) into AppleScript editor, and it runs fine.

Apparently, "POSIX file" in ApplescriptObjC doesn't make a file object as the language specification requires. Instead it makes an NSObject.

I need to have an applescript file specifier to provide to Adobe Illustrator's do javascript command, and I need to use NSBundle's functions to get the javascript file, which is packaged in my application bundle.

Am I doing something wrong?

解决方案

You will see the same behavior in a Finder or System Events tell statement. The solution is the same for ASObjC - you need to use it as a coercion:

set jsHFSFile to (theJSPath as POSIX file)
