What are the basic "steps" for deployment of an SQLite database file in an iPhone app? creating the db ...
I have a grouped table view that utilizes two different custom table cells. When i scroll through the table so that one (or more) of the cells goes either above or below what is visible those cells become blank. When i scroll back up (or down) to view these cells they are still blank. Why is this? The cells showed the appropriate con...

I'm trying to build for multiple targets in Xcode, to simplify the process of creating a "lite" and "pro" version of my application.

However, I'm having problems actually getting it to work due to an error trying to launch the second tar...

I have a UIScrollView with images in it. When the user reaches the last image and swipes the finger for next image, I want to show the first image. Similarly, when the user is at the first image and swipes for previous image, I want to show the last image. In short, it will be a circular sort of a thing. How can I implement this? ...
Are there any open source coverflow-like API's/libraries available for the iPhone? I've found one implementation that is licensed per application, however, I'd much prefer to go the open source route. Also, I'm interested in libraries that use only public API's as others may keep an app from getting published into the App Store. ...

How do I most efficiently determine whether my idea for an iPhone app has been done already? iTunes's search isn't great for this purpose, and the websites I've seen covering iPhone apps are not comprehensive in their coverage. (Perhaps I just haven't found THE website that does it.) I'm not yet signed up in the iPhone developer program;...
