This chapter is from the book


This hour described the use of common input features and a few important output options. You learned that text fields and text views both enable the user to enter arbitrary input constrained by a variety of different virtual keyboards. Unlike text fields, however, text views can handle multiline input as well as scrolling, making them the choice for working with large amounts of text. We also covered the use of buttons and button states, including how buttons can be manipulated through code.

We continue to use the same techniques you used in this hour throughout the rest of the book, so don’t be surprised when you see these elements again.
