In the interest of saving myself a lot of work, I looked around and found Cocos2d. It looks like it has exactly what I need (OpenGL ES, relatively simple to work with), but I've run into a problem. I don't kn...

However once you move the UIImageView, it will suddenly update and change to false. Here are the important bits of my code: I set up the animation in the standard way: UIImageView* newImageView = ... newImageView.animat...

I'm trying to display a small refresh button using UIButton in a standard UIView using the refresh icon built into UIKit. If I use an UIBarButtonItem it can be created as a refresh button, but I've had no luck in using this icon in other places.

Hello, I am using FMDB to deal with my database which works fine. The app uses a background thread which is doing some work and needs to access the database.

You have to have one per thread, but beyond that ... should you have more? Is it harmful to have more? For instance, I'm tempted to build my app around having one NSManagedObjectContext per tab, handling the subset of the overall persistent store that appears on that particular tab.
