Every iOS app consists of what we see on the screen and how we transition from one screen to another.
These two fundamental ideas are captured in iOS storyboards as scenes and segues.
This survey of iOS storyboards demonstrates many useful techniques. In this short, 150 page book, the prose, videos, and screenshots will combine to demonstrate how to best take advantage of storyboards in the apps you are building.
To follow along with the material in this book, you will need a Mac running either Yosemite or Mavericks with Xcode 6.x installed.
Note that the book examples and descriptions are designed for Xcode 5 and iOS 7 using modern Objective-C. All of the concepts remain relevant, but improvements to Xcode 6 and iOS 8 bring alternate techniques for accomplishing some of the same results.
