Я создал представление в моем контроллере View, которое имеет UISegmentControl и UIScrollView
let segmentControl : UISegmentedControl = {
let segmentItems = ["Personal","Statistics","Calendar"]
let segmentControl = UISegmentedControl(items: segmentItems)
segmentControl.selectedSegmentIndex = 0
segmentControl.addTarget(self, action: #selector(selectIn(sender:)), for: .valueChanged)
segmentControl.translatesAutoresizingMaskIntoConstraints = false
return segmentControl
}()
let subView : UIScrollView = {
let view = UIScrollView()
view.backgroundColor = .red
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
В viewDidLoad я добавил
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.navigationBar.isHidden = true
view.addSubview(segmentControl)
view.addSubview(subView)
setLayout()
}
и добавил макет следующим образом
func setLayout(){
NSLayoutConstraint.activate([
segmentControl.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 10),
segmentControl.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor, constant: 20),
segmentControl.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -20),
segmentControl.heightAnchor.constraint(equalToConstant: 30),
subView.topAnchor.constraint(equalTo: segmentControl.bottomAnchor, constant: 10),
subView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor, constant: 20),
subView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -20),
subView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor),
])
}
и попытался добавить PersonalView (UIView) при нажатии любого сегмента ControlControl
@objc func selectIn(sender: UISegmentedControl){
subView.addSubview(pvc)
}
Мой персональный вид выглядит следующим образом
class PersonalView: UIView, UICollectionViewDelegate, UICollectionViewDataSource, UITableViewDelegate, UITableViewDataSource {
let tempValueForTable : Int = 10
let todayLabel : UILabel = {
let label = UILabel()
label.text = "Today"
label.font = .montserratSemiBold
label.textAlignment = .center
label.backgroundColor = .green
label.translatesAutoresizingMaskIntoConstraints = false
return label
}()
override init(frame: CGRect) {
super.init(frame: frame)
addSubview(todayLabel)
setLayout()
}
private func setLayout(){
NSLayoutConstraint.activate([
todayLabel.topAnchor.constraint(equalTo: self.topAnchor),
todayLabel.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 20),
todayLabel.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -20),
todayLabel.heightAnchor.constraint(equalToConstant: 25),
])
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}}
Тем не менее я не могу получить представление, и в дальнейшем обновлении мне нужно добавить больше представления в том же ScrollView
