Layout

The layout of the InputBarAccessoryView is made of of 4 InputStackView's and an InputTextView. The padding of the subviews can be easily adjusted by changing the padding and textViewPadding properties. The constraints will automatically be updated.

It is important to note that each of the InputStackView's to the left and right of the InputTextView are anchored by a width constraint. This way the InputTextView will always fill the space inbetween in addition to providing methods that can easily be called to hide all buttons to the right or left of the InputTextView by setting the width constraint constant to 0. The bottom and top stack views are not height constraint and rely on their intrinsicContentSize

func setLeftStackViewWidthConstant(to newValue: CGFloat, animated: Bool)

func setRightStackViewWidthConstant(to newValue: CGFloat, animated: Bool)

Reactive Hooks

Each InputBarButtonItem has properties that can hold actions that will be executed during various hooks such as the button being touched, the UITextViewtext changing and more! Thanks to these easy hooks with a few lines of code the items can be easily resized and animated similar to that of the Facebook messenger app.

// MARK: - Hooks

public typealias InputBarButtonItemAction = ((InputBarButtonItem) -> Void)    

private var onTouchUpInsideAction: InputBarButtonItemAction?
private var onKeyboardEditingBeginsAction: InputBarButtonItemAction?
private var onKeyboardEditingEndsAction: InputBarButtonItemAction?
private var onKeyboardSwipeGestureAction: ((InputBarButtonItem, UISwipeGestureRecognizer) -> Void)?
private var onTextViewDidChangeAction: ((InputBarButtonItem, InputTextView) -> Void)?
private var onSelectedAction: InputBarButtonItemAction?
private var onDeselectedAction: InputBarButtonItemAction?
private var onEnabledAction: InputBarButtonItemAction?
private var onDisabledAction: InputBarButtonItemAction?
