Installation via Swift Package Manager (SPM)

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. Once you have your Swift package set up, adding InputBarAccessoryView as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/nathantannar4/InputBarAccessoryView.git", .upToNextMajor(from: "4.5.0"))
]

You can also add it via XCode SPM editor with URL:

https://github.com/nathantannar4/InputBarAccessoryView.git

To make RxSwift/RxCocoa extensions work you need to explicitly import Rx dependencies.

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 UITextView text 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?
