multithreading - 用applescriptobjc实现GDC

我正在制作这个简单的ApplescriptObjC可可应用程序，就像我理解多步练习一样，它是一个文本字段和一个标签，我试图在输入文本字段时实时更新标签，但只能得到按下Enter键后立即更新，但不是实时更新，是否知道如何使它起作用？这是代码。
谢谢

    script AppDelegate

    property parent : class "NSObject"
    property prgLabel: missing value
    property subjectFeild: missing value


    on applicationWillFinishLaunching_(aNotification)
        -- Insert code here to initialize your application before any files are opened
    activate
  end applicationWillFinishLaunching_

    on applicationShouldTerminate_(sender)
        -- Insert code here to do any housekeeping before your application quits
        return current application's NSTerminateNow
    end applicationShouldTerminate_

    on textChange_(sender)

        set SU to subjectFeild's stringValue() as string
        prgLabel's setStringValue_(SU)

    end textChange_


end script

最佳答案

1）将文本字段的委托设置为您的应用程序委托。

2）实现controlTextDidChange，在编辑过程中每次文本字段更改时都会调用该控件。

script AppDelegate
    property parent : class "NSObject"

    -- IBOutlets
    property theWindow : missing value
    property prgLabel: missing value
    property subjectFeild: missing value

    on applicationWillFinishLaunching:aNotification
        subjectFeild's setDelegate:me
    end applicationWillFinishLaunching_


    on controlTextDidChange:notification
        prgLabel's setStringValue:subjectFeild's stringValue()
    end

end script
