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
}
