Ich habe eine benutzerdefinierte UIControl:Benutzerdefinierte Segmented Steuerung Nicht Schalt Ansichten
import UIKit
@IBDesignable class FeedViewSC: UIControl {
fileprivate var labels = [UILabel]()
var thumbView = UIView()
var items: [String] = ["Tab1", "Tab2"] {
didSet {
setupLabels()
}
}
var selectedIndex : Int = 0 {
didSet{
displayNewSelectedIndex()
}
}
@IBInspectable var font : UIFont! = UIFont.systemFont(ofSize: 13) {
didSet {
setFont()
}
}
override init(frame: CGRect) {
super.init(frame: frame)
setupView()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
setupView()
}
func setupView() {
layer.cornerRadius = 5
layer.borderColor = UIColor(red: 239/255, green: 239/255, blue: 239/255, alpha: 1).cgColor
layer.borderWidth = 2
backgroundColor = UIColor(red: 239/255, green: 239/255, blue: 239/255, alpha: 1)
setupLabels()
insertSubview(thumbView, at: 0)
}
func setupLabels() {
for label in labels {
label.removeFromSuperview()
}
labels.removeAll(keepingCapacity: true)
for index in 1...items.count {
let label = UILabel(frame: CGRect.zero)
label.text = items[index-1]
label.textAlignment = .center
label.font = UIFont(name: "Nunito",size: 17)
label.textColor = UIColor(red: 51/255, green: 51/255, blue: 51/255, alpha: 1)

labels.append(label)
}
}

super.layoutSubviews()
var selectFrame = self.bounds
let newWidth = selectFrame.width/CGFloat(items.count)
selectFrame.size.width = newWidth
thumbView.frame = selectFrame
thumbView.backgroundColor = UIColor(red: 255/255, green: 255/255, blue: 255/255, alpha: 1)
thumbView.layer.cornerRadius = 5

calculatedIndex = index
}
}
if calculatedIndex != nil {

sendActions(for: .valueChanged)
}
return false
}
func displayNewSelectedIndex(){
if(self.selectedIndex == -1){
self.selectedIndex = self.items.count-1
}
let label = labels[selectedIndex]
UIView.animate(withDuration: 0.5, delay: 0.0, usingSpringWithDamping: 0.90, initialSpringVelocity: 0.8, options: [], animations: {
self.thumbView.frame = label.frame
}, completion: nil)
}
func setFont(){
for item in labels {
item.font = font
}
}
}
ich emeded es in meinem Viewcontroller und versuchte es programitcally zwischen zwei Ansichten wechseln zu müssen:
import UIKit
class FeedViewController: UIViewController {
let feedViewSC = FeedViewSC()
let firstView: UIView = {
let view = UIView()
view.backgroundColor = UIColor.red
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
let secondView: UIView = {
let view = UIView()
view.backgroundColor = UIColor.blue
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
let (width, height) = UIScreen.main.bounds.wh
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.white
view.addSubview(firstView)
view.addSubview(secondView)
setupContainerViews()
firstView.isHidden = false
secondView.isHidden = true
myTravel.selectedIndex = 0
let feedControl = FeedViewSC(frame: CGRect(x: 65, y: 5, width: width-130, height: 35))
feedControl.autoresizingMask = [.flexibleWidth,.flexibleHeight]
self.navigationController?.navigationBar.addSubview(feedControl)
feedControl.addTarget(self, action: #selector(segmentedControlSwitch), for: .valueChanged)
}
func segmentedControlSwitch(_ sender: FeedViewSC) {
switch feedViewSC.selectedIndex {
case 0:
firstView.isHidden = false
secondView.isHidden = true
case 1:
firstView.isHidden = true
secondView.isHidden = false
default:
break;
}
}
func setupContainerViews() {
firstView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
firstView.topAnchor.constraint(equalTo: topLayoutGuide.bottomAnchor, constant: 8).isActive = true
firstView.bottomAnchor.constraint(equalTo: bottomLayoutGuide.topAnchor).isActive = true
firstView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
secondView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
secondView.topAnchor.constraint(equalTo: topLayoutGuide.bottomAnchor, constant: 8).isActive = true
secondView.bottomAnchor.constraint(equalTo: bottomLayoutGuide.topAnchor).isActive = true
secondView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
}
override func viewDidAppear(_ animated: Bool) {
let img = UIImage()
self.navigationController?.navigationBar.shadowImage = img
self.navigationController?.navigationBar.setBackgroundImage(img, for: UIBarMetrics.default)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension CGRect {
var wh: (w: CGFloat, h: CGFloat) {
return (size.width, size.height)
}
}
Ich bin nicht Sicher, was ich tue, ist falsch. Aus irgendeinem Grund wechselt der Code nicht zwischen FirstView und SecondView. Derzeit wird nur die erste Ansicht angezeigt. Bitte beachte, dass ich dies ohne Storyboards und programmgesteuert durchführe.
Ich habe nicht meinen Mac jetzt um mich herum. Aber wenn ich mir deinen Code ansehe, denke ich, dass er etwas damit zu tun hat, wie du 'segmentierterControlSwitch' nennst. –
