NarrativeView

Madlib style form view

Features

1. Text fields expand while users are entering text, reflowing to the next line if necessary
2. Labels are broken up as individual words
3. All text fields are validated via passed in lambda and appearance is updatable via the NarrativeTextFieldSettableAppearance protocol
4. Appearance of fields, buttons, and labels is completely customizable

Usage

1. Create an instance of Narrative view via either IB or programatically.
2. Implement the NarrativeViewDelegate delegate on your VC and set narrativeViewDelegate
3. Describe your view by chaining together label, textfield or button methods followed by a call to initialLayout

e.g.

    narrativeView.label(createLabel: newLabel, text: "Enter your")
        .textField(createTextField: newField("user name")) { field in
            return self.validateUsername(field.text)
        }
        .label(createLabel: newLabel, text: "and")
        .textField(createTextField: newField("password")) { field in
            return self.validatePassword(field.text)
        }
        .label(createLabel: newLabel, text: "to log in.")
        .initialLayout()
