The iOS Developer Library has an excellent article on creating custom container view controllers, so I won’t go too much into detail on that. This post will mainly focus on MFWalkthrough, an iOS library I created to simplify the process of sequentially stepping through view controllers.

Consider the use case of gathering information from a user, such as personal data during registration. If the amount of data you’re gathering is relatively small, you may usually get away with placing all inputs in a single view, such as the UITableView form pattern. There are, however, scenarios where it makes to split up the data gathering process across multiple views. Maybe there’s a sequential order to the information you’re gathering with some data depending on other data being valid. Or maybe you have large UI elements that require more space. This is where MFWalkthrough comes in.

Regularly is too consistent for me. I enjoy reading, especially metaphysics and crime thrillers, but I don’t do it regularly. Even if I could make some time to read everyday, which I probably can, I wouldn’t. Why? Because I would probably be obsessing over some Wikipedia article or GitHub project.

If I pick up a book, I will only continue reading it regularly if I am obsessed with it, and I could be switched off from one obsession to another.
