JVFloatLabeledTextField is the first implementation a UX pattern that has come to be known the "Float Label Pattern".
Due to space constraints on mobile devices, it is common to rely solely on placeholders as a means to label fields. This presents a UX problem, in that, once the user begins to fill out a form, no labels are present.
This UI component library, which includes both a
UITextView subclass, aims to improve the user experience by having placeholders transition into floating labels that hover above the fields after they are populated with text.
The component is officially supported for iOS 7 and greater.
