Hi, I have written an application with a draggable annotation which I have added on top of a MKMapView. I've added a CLLocationCoordinate2D variable called myloc in my main view controller to store the coordinate (lat,lng) values whenever I drag the annotation. My question is how do I update the myloc property value in the super parent ...

I have a collection of NSObjects that I want to store in a 2D array generated at run time.

And the detailsview responds back to this table through a delegate after the file download is complete. But, when this tableview itself is...
If I attempt to animate the frame height of a tableView (ex: height -= 200), the cells that appear in the last 200px disappear suddenly before the smooth animation of the frame completes. To make sure that it's nothing else I'm doing, I created a new View-Based application. In the main viewController I create my own tableview with enoug...

I keep running across references to MacRuby and was wondering if any of you have used it for iPhone/Objective C programming. The MacRuby website says, "the goal of MacRuby to enable the creation of full-fledged Mac OS X applications which do not sacrifice performance in order to enjoy the benefits of using Ruby." So, my question is: wh...
