Initialization.


                                              
                                                let toolbar: Toolbar = Toolbar()


                                              
                                                let toolbar: Toolbar = Toolbar()
lazy var camera: ToolbarItem = {

let item: ToolbarItem = ToolbarItem(image: #imageLiteral(resourceName: “camera”), target: nil, action: nil)

return item

}()
lazy var microphone: ToolbarItem = {

let item: ToolbarItem = ToolbarItem(image: #imageLiteral(resourceName: “microphone”), target: nil, action: nil)

return item

}()
lazy var picture: ToolbarItem = {

let item: ToolbarItem = ToolbarItem(image: #imageLiteral(resourceName: “picture”), target: nil, action: nil)

return item

}()
var toolbarBottomConstraint: NSLayoutConstraint?
override func loadView() {

super.loadView()

self.view.addSubview(toolbar)

self.toolbarBottomConstraint = self.toolbar.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: 0)

self.toolbarBottomConstraint?.isActive = true

}
override func viewDidLoad() {

super.viewDidLoad()

self.toolbar.maximumHeight = 100

self.toolbar.setItems([self.camera, self.picture, self.microphone], animated: false)

}

Hide items


                                              
                                                func hideItems() {

self.camera.setHidden(false, animated: true)

self.microphone.setHidden(false, animated: true)

self.picture.setHidden(false, animated: true)

}

Stretchable TextView

You can control the height by setting maximumHeight.


                                              
                                                // ViewController
override func viewDidLoad() {

super.viewDidLoad()

self.toolbar.maximumHeight = 100

let textView: UITextView = UITextView(frame: .zero)

textView.delegate = self

textView.font = UIFont.systemFont(ofSize: 14)

self.toolbar.setItems([textView], animated: false)

}
// UITextViewDelegate

func textViewDidChange(_ textView: UITextView) {

let size: CGSize = textView.sizeThatFits(textView.bounds.size)

if let constraint: NSLayoutConstraint = self.constraint {

textView.removeConstraint(constraint)

}

self.constraint = textView.heightAnchor.constraint(equalToConstant: size.height)

self.constraint?.priority = UILayoutPriorityDefaultHigh

self.constraint?.isActive = true

}
var constraint: NSLayoutConstraint?
