Text Field Classes: The Inputs

Text Field

This is a single-line text input. It‘s subclassed from UITextField and supports all the features you’d expect from a UITextField:

  • Placeholder
  • Overlay views (left and right / leading and trailing)
  • Custom fonts, colors
  • Clear button

as well as new features:

  • Underline
  • Labels below the input
  • Custom layouts
  • Persistable placeholder
  • Border view

Multi-line Text Field

This is a multi-line text input. It's subclassed from UIView with an embedded UITextView. It supports all the features of the single-line text field and UITextView plus:

  • Minimum number of lines

Text Field Classes: The Controllers

Default Text Input Controller

This class holds all the ‘magic’ logic necessary to make the naturally ‘dumb’ text field and text view behave with:

  • Animations
  • Styles
  • Errors
  • Character counts

Full Width Text Input Controller

Similar to the default text input controller but optimized for full width forms like emails.
