I wish this post had more specifics about the coding or design. As is, it's screenshots and generic descriptions of difficulty. It would be good to hear why you made specific design decisions, why you didn't want to use IB, breakthroughs you had creating custom UIAlertViews etc.
That type of post will be forthcoming in some of the deep technical dive posts I have lined up. They will be more interesting if I am able to open-source some of the code, but I wasn't able to get those kinds of decisions made by the time this current post was published for our launch announcement. Stay tuned.
Yes. If the custom UI is primarily imaged-based it is easy to make with a storyboard/xib. For example, the brushes in iPhoto for iOS are made with a xib.
