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