A few months ago I mentioned an excellent UICollectionView template for creating a magazine rack view from Tope Abayomi from the App Design Vault.
Here’s another great example of design from Tope providing a collection of different iPhone app navigation bars inspired by successful apps within the app store that you can download for free and use within your apps.
Here are a few images showing a few of the styles available:
You can find the free navigation bar graphics over at the App Design Vault here.
There’s 27 navigation bars in total so if you’ve been struggling to find that right look for a nav bar there’s a good chance you’ll find something in there.
