У меня есть ViewController со скрытым представлением (назовем его boxInsideView) при загрузке. Я бы хотел, чтобы этот контроллер boxInsideView или файл .swift запускались всякий раз, когда пользователь щелкает по полю, а не при загрузке контроллера представления. Например, если бы я нажал addSubview(boxInsideView, щелкнув по полю.
Создание моей boxInsideView
let cajasInsideView : CajaInsideView = {
let cajasInside = CajaInsideView()
cajasInside.delegate = self
return cajasInside
}()
Вкл. viewDidLoad() У меня есть этот код:
scrollView.addSubview(cajasInsideView)
scrollView.addSubview(cajasView)
scrollView.addSubview(collectionView)
cajasView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 0).isActive = true
cajasView.topAnchor.constraint(equalTo: scrollView.topAnchor, constant: 0).isActive = true
cajasView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true
cajasView.heightAnchor.constraint(equalToConstant: 150).isActive = true
if !isClosed {
cajasInsideView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 0).isActive = true
cajasInsideView.autoPinEdge(.top, to: .bottom, of: cajasView, withOffset: -10)
cajasInsideView.heightAnchor.constraint(equalToConstant: 0).isActive = true
cajasInsideView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true
}
topConstraint = NSLayoutConstraint(item: collectionView, attribute: .top, relatedBy: .equal, toItem: cajasView, attribute: .bottom, multiplier: 1, constant: 0)
scrollView.addConstraint(topConstraint!)
collectionView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor, constant: 0).isActive = true
collectionView.heightAnchor.constraint(equalToConstant: 1000).isActive = true
collectionView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true
Когда автоматически запускается scrollView.addSubview(cajasInsideView), запускается мой файл .swift.
Я хочу добавить это представление, а также ограничения и анимацию после щелчка этого окна.
Моя openBox() функция:
@objc func openBox(){
if isClosed {
shareDropDown.dataSource = ["Añadir objetos a esta caja", "Añadir objeto nuevo a esta caja", "Sacar objeto de esta caja"]
shareDropDown.selectionAction = { [unowned self] (index: Int, item: String) in
if index == 1 {
let storyboard = UIStoryboard(name: "Trastero", bundle: nil)
let uploadTrastero = storyboard.instantiateViewController(withIdentifier: "UploadTrasteroViewController") as! UploadTrasteroViewController
uploadTrastero.navigationItem.leftItemsSupplementBackButton = true
self.navigationController?.pushViewController(uploadTrastero, animated: true)
}
if index == 0 {
self.setMoverObjeto()
}
print("Selected item: \(item) at index: \(index)")
}
shareDropDown.width = 250
scrollView.removeConstraint(topConstraint!)
topConstraint = NSLayoutConstraint(item: collectionView, attribute: .top, relatedBy: .equal, toItem: cajasInsideView, attribute: .bottom, multiplier: 1, constant: 0)
UIView.animate(withDuration: 0.5, delay:0, usingSpringWithDamping:0.7, initialSpringVelocity:0, options: .curveEaseOut, animations: {
