Mac Forum / Programming / Mac Programming / August 2007Using Objective-C From JavaScript
I'm really not very good at this. I've written quite a lot of stuff in Cocoa but it has all been entire Applications and now I need to write a plugin or a framework or something. I'm following the instructions on this page http://developer.apple.com/documentation/AppleApplications/Conceptual/Safar iJSProgTopics/index.html and it gets into a a nice example involving BasicAddressBook and talks about editing a .m file. But what kind of project is this ? Should I create it in Xcode by using 'Cocoa Application' or 'Cocoa Bundle' or is it a library or what ? It's not an application, in that 'main' does nothing and it has no interface, so I guess the application options are wrong. I assume I should link to WebKit.framework. But the page mentions WebScriptObject.h . Should I be importing that somewhere, or is it part of Cocoa or WebKit.framework or something else that means it will be implicitly incorporated ? Simon.

That documentation applies if you're writing a Mac OS X application that uses WebKit for some or all of its UI. Cocoa Application, or document-based application, or whatever, is a decision that depends on what the application does. The Objective-C objects that can then be used from JavaScript are whatever is in your application that's appropriate to the WebKit portion of the app. Are you looking to write a plugin that would work in Safari? That sounds like it might be what you mean but it's not clear.

It doesn't need to have any free-standing abilities at all, I'm just providing an interface between JavaScript and something I can't do in JavaScript. And it doesn't need to be a fully-fledged View handler because it doesn't draw anything on the web page, it just accepts text data from JavaScript, processes it, and returns the results as text.

Some quick searching at developer.apple.com turns up "Web Kit Plug-In Programming Topics" at <http://developer.apple.com/documentation/InternetWeb/Conceptual/WebKit_P luginProgTopic/index.html>, and some sample code at <http://developer.apple.com/samplecode/WebKitPluginStarter/index.html>. The "readme" in the sample code steps you through setting up an Xcode project for such a plugin. SignatureTom "Tom" Harrington MondoMouse makes your mouse mightier See http://www.atomicbird.com/mondomouse/ [Sorry, for some reason my client won't let me thread this correctly.] Tom: thanks for those projects, but they're for 'Views': thing that result in something that's shown on your web page. They include lots of stuff that isn't needed if all you're doing is talking to JavaScript. David: That 'Birthdays' plugin seems to be what I needed. I hadn't thought of looking through the widgets since I'm not writing a widget but the plug-in is as simple as I need to go. Thanks very much. Dammit. Now I have to actually write the thing. Simon.

It sounds like you want to download the .dmg from http://developer.apple.com/samplecode/Birthdays/ and open and edit the enclosed Xcode project |
