Last week, my partner showed me his design for our application. Everything is great, easily implemented with some custom controls. But wait, something is not in my knowledge.
A button with gradient border. Never try it before. Up to now, I just created gradient background views 2 times in previous projects. Googled and found some good results.

I started iOS development as a .NET developer. My first impression, Storyboard is really really interesting. 80% UI of my apps is built in Storyboard. I can't imagine how I can develop iOS without Storyboard.
There are many discussions about Auto Layout with Storyboard or Programmatically is better. But no one wins. Everyone has own reason and belief.
This post is my personal opinion. It's written by a developer can't live without Storyboard, and now he abandons it.

You can see it anywhere. It's very popular in home screen, gallery screen. See how to do that.
Is Initial View ControllerHeaderCell. Set cell's height to 400.
