UITextField subclass with placeholders that change into floating labels when the field is populated with text.
Currently, JVFloatLabeledTextField used alone is iOS 6+, but JVFloatLabeledTextView requires iOS 7 due to the use of UITextView's textContainer. I would welcome pull requests to make JVFloatLabeledTextView iOS 6 compatible.
Credits for the concept to Matt D. Smith (@mds), and his original design:
