### Installation via Swift Package Manager (SPM)



The [Swift Package Manager](https://swift.org/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: "6.0.0"))

]

```

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

```

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

```

## 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`



```swift

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.



```swift

// 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?

```
