I have an app, using Core Data with a SQLite store. At some point I'd like to remove all objects for a few entities. There may be close to a thousand objects.

I've used the Activity Monitor and Object Allocations tools in xcode to check out my application and the sample facebook login app and what I've found is that they all of them eat about 6-10M (!) the first time the user visits the page.

I have narrowed down an ugly bug, but since it seems like something internal to the nib/Interface Builder, I'm at a loss of what to do next. I've got a UIView created in IB which functions as a custom dialog box. It shows a message and two buttons. (Proceed or Cancel.) Both buttons have a Background image set in Interface Builder. Some...

I have existing users of a paid for app on the App Store. I'd like to transition the app to a free app with unlock-able features.

OR, as I expect, must we maintain...
