Form

FormView

The FormView.swift class can render a set of InputFields with support a set of useful features for them.

• Auto-jump between every InputField.
• Animated layout of every InputField.
• Sizing and layout of every InputField.
• Field validation on submit.
• Scrolling if needed.
• DynamicType.

Usage

Create an instance of FormView.

let formView = FormView()

Add new inputs. Inputs will be listed in the order they are inserted.

let username = InputField(style: .email)
let password = InputField(style: .password)

formView.addInputFields([username, password])

You can also add custom views as headers or footers.

let formView = FormView()
let headerView = UILabel()
headerView.text = "Change email"

formView.addHeaderView(headerView)

There are three kinds of custom views:

• headerView: Placed at top of the form (above the first input).
• detailView: Placed in the middle of the form (between the last input and the submit button).
• footerView: Placed at the bottom of the form (below submit button).

Note that the FormView manages the scrolling of the form, so there may be cases where using those custom views is useful.

Sizing

Forms have an intrinsic content size that matches the current content. Note that the inputs can grow vertically so you shouldn't force a specific height. Usually, the only thing you have do is to constrain it to the edges of the screen.
