Creating Dashbord Widgets (using XCode?) based on iPhone app
Some time ago I developed an app for a client. It's basically a simple calculator. Because they like it so much they asked me if it would be possible to create dashboard widget with the same functionality based on the iPhone app.
I have never before developed a widget, I only know that they are mostly html + css based, so this raises a few questions for me:
- Is using html + css the only way to create a widget?
- If no:
- Can XCode be used to create a widget?
- Is it possible to wrap Cocoa applications into a widget?
- If yes, are there any convenience tools to create a Cocoa-Touch-like look, feel and functionality (especially of tableviews)?
I guess the superquestion to all the above questions would be: Is there any chance I can reuse some parts of the existing iPhone project or do I need to create the widget from scratch?
In your /Developer/Applications/ directory, you find *Dashcode which might help you develop a Dashboard widget.
Yes it's mostly HTML+CSS. You can add a Cocoa plug-in, as described here. However, that Cocoa plug-in can't draw using Cocoa methods onto the webview of the widget.
You can create a webkit plugin as described here, which can draw using Cocoa methods onto the webview of the widget. You can package them inside a widget.
However, the Cocoa methods you can use are AppKit methods, not UIKit methods. Specifically, you don't have UITableView, you have NSTableView which are rather different beast.
I hope Apple add an iOS emulation layer in OS X 10.7, so that you can load an iPhone app to the dashboard. That would be awesome, if Apple can find a way to emulate the touch events nicely...
