What are the ways to create a button and write its function?

Trenton

If there's possibility, write a code for a button that would change its name when compressed.

import SwiftUI
struct ContentView: View {

var body: some View {

Text("gwg")

}

}
struct ContentView_Previews: PreviewProvider {

static var previews: some View {

ContentView()

}

}

I'm writing iOS. Swift 5, Xcode 11.

Create a variable. @State var buttonName = "gwg"
Then the button itself. Button(buttonName){ buttonName = "newName" }
Something like that. I hope I helped!

What mistake are you making? Try the dialogue buttons to define the kv file. Clean up where you put it and put the button on it: on_release: app.show_alert_dialog()Closure of the dialogue windowdef callback(self, *args): self.dialog.dismiss()

On the basis of your code, I wrote the following example. The point is, the properties bezAnimation.toValue The path to which the animation should take place should be attributed.import UIKit class TabBarView: UIView { private var currentIndex = 0 private var nextIndex = 0 private var tabsCount: Int { items.count } private var tabWidth: CGFloat { guard items.count > 0 else { return 0 } return bounds.width / CGFloat(items.count) } private var tabHeight: CGFloat { bounds.height } private var curveLayer: CAShapeLayer! var items: [String] = [] var animated = true override init(frame: CGRect) { super.init(frame: frame) setup() } required init?(coder: NSCoder) { super.init(coder: coder) setup() } func setup() { let recognizer = UITapGestureRecognizer(target: self, action: #selector(tap(_:))) addGestureRecognizer(recognizer) } override func draw(_ rect: CGRect) { drawCurve(for: currentIndex) } private func drawCurve(for index: Int) { let fillColor: UIColor = .white let strokeColor: UIColor = .gray // 1. draw current tab let currentTabBezierPath = drawPathBorder(for: index) currentTabBezierPath.close() if curveLayer == nil { curveLayer = CAShapeLayer() curveLayer.fillRule = .evenOdd curveLayer.frame = bounds curveLayer.fillColor = fillColor.cgColor curveLayer.strokeColor = strokeColor.cgColor curveLayer.lineWidth = 1 layer.addSublayer(curveLayer) } curveLayer.path = currentTabBezierPath.cgPath if currentIndex == nextIndex { return } if (self.animated) { // 2. animate to next tab let nextTabBezierPath = drawPathBorder(for: nextIndex) let bezAnimation = CABasicAnimation(keyPath: "path") // The next two line preserves the final shape of animation, // if you remove it the shape will return to the original shape after the animation finished // see https://stackoverflow.com/a/26848581/3004003 bezAnimation.fillMode = .forwards bezAnimation.isRemovedOnCompletion = false bezAnimation.toValue = nextTabBezierPath.cgPath bezAnimation.duration = 3.3 bezAnimation.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut) curveLayer.add(bezAnimation, forKey: nil) } currentIndex = nextIndex } private func drawPathBorder(for index: Int) -> UIBezierPath { let bezPath = UIBezierPath() let floatIndex = CGFloat(index) let leftPoint = CGPoint(x: (floatIndex * tabWidth), y: 0) let leftPointCurveUp = CGPoint( x: ((tabWidth * floatIndex) + tabWidth / 5), y: 0) // Casting to CGFloat to avoid "The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions" let leftPointCurveDown = CGPoint( x: ((floatIndex * tabWidth) - tabWidth * CGFloat(0.2)) + tabWidth / CGFloat(4.0), y: CGFloat(tabHeight * 0.40)) let middlePoint = CGPoint( x: (tabWidth * floatIndex) + tabWidth / 2, y: tabHeight * 0.4) let middlePointCurveDown = CGPoint( x: (((floatIndex * tabWidth) - tabWidth * CGFloat(0.2)) + tabWidth / CGFloat(10.0)) + tabWidth, y: tabHeight * 0.40) let middlePointCurveUp = CGPoint( x: (((tabWidth * floatIndex) + tabWidth) - tabWidth / 5.0), y: 0) let rightPoint = CGPoint(x: (tabWidth * floatIndex) + tabWidth, y: 0) bezPath.move(to: leftPoint) bezPath.addCurve(to: middlePoint, controlPoint1: leftPointCurveUp, controlPoint2: leftPointCurveDown) bezPath.addCurve(to: rightPoint, controlPoint1: middlePointCurveDown, controlPoint2: middlePointCurveUp) let width = UIScreen.main.bounds.width bezPath.addLine(to: CGPoint(x: width, y: 0)) bezPath.addLine(to: CGPoint(x: width, y: 83)) bezPath.addLine(to: CGPoint(x: 0, y: 83)) bezPath.addLine(to: CGPoint(x: 0, y: 0)) bezPath.addLine(to: leftPoint) return bezPath } @objc func tap(_ recognizer: UITapGestureRecognizer) { let location = recognizer.location(in: self) nextIndex = tabIndex(with: location) setNeedsDisplay() } private func tabIndex(with location:CGPoint) -> Int { Int(location.x / tabWidth) } }

You've got an incorrect base of URL onloaded page. I see three options:(1) (cool) We load html as a line, and we display the correct URL. PS: Other references can fly let webView: UIWebView! let url: NSURL! let baseURL: NSURL! let session = NSURLSession.sharedSession() let task = session.dataTaskWithURL(url) { (data, _, err) in if let data = data { let str = NSString(data: data, encoding: NSUTF8StringEncoding) dispatch_async(dispatch_get_main_queue()) { webView.loadHTMLString(str, baseURL: baseURL) } } } (2) Use https://habrahabr.ru/post/237367/ ♪ You can intercept the beginning of the loading and replace the wrong one. NSURL♪ (reasonably flexible method, recommended)(3) Through JS: all img and replace url♪ Here. https://stackoverflow.com/a/9825358/820795 a small example of use. This operation needs to be performed only after UIWebView It'll be loaded. It will be. minus This way, the pictures will start to be late.

How to make a parent class and inherit it?class MYBaseViewController : UIViewController { override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) // GAのスクリーントラッキングコードをここに記述 } } For each class:class MYViewController : MYBaseViewController { override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated)//これを忘れないこと。 //通常通りのコードを記述 } } When implementing with extension, I think that it will be an addition of the method.I think that there is no change in what I need to call manually.

Use segueIt'll look like:class VC1: UIViewController { // MARK: - Private Instance Attributes private var stringAttr: String? = "Hello" // MARK: - Navigation override func prepare(for segue: UIStoryboardSegue, sender: Any?) { guard let identifier = segue.identifier else { return } switch identifier { case "GoToVC2": guard let viewController = segue.destination as? VC2 else { break } viewController.stringAttr = stringAttr viewController.stringAttrChangedClosure = { [weak self] (newString) in guard let strongSelf = self else { return } strongSelf.stringAttr = newString } default: break } } } class VC2: UIViewController { // MARK: - Public Instance Attributes var stringAttr: String? = "Hello" { didSet { stringAttrChangedClosure?(stringAttr) } } var stringAttrChangedClosure: ((_ newString: String?) -> Void)? } I want to draw your attention. prepare(for:segue) The shape elements (IBOutlet) cannot be addressed as they have not yet been initiated at this time, so the data storage will need to create a temporary variable (IBOutlet)stringAttr in this example. The line 'viewControllersome.Label.test = stringAttr' will cause a mistake of implementation if someLabel - That's it. @IBOutlet♪Also, in order to change the data on the transferring side (VC1), the example always requires the use of blocks.

I didn't get it right, but I'll try to help.um = ()=>{ alert("Chamou primeira") } dois = ()=>{ alert("Chamou segunda") } $("btn_one").click(()=>{ um() dois() }) //Note that the click event should be below the two functions (one, two), because when the button is clicked, JavasScript will call a function that has been loaded upon the function that captures the click.

I'll join you. Valera KvipUse it. https://firebase.google.com/docs/reference/js/firebase.database.Query ♪ The old Firebase Database should not be used, it's really confusing and uncomfortable.And the search can be done, for example:db.collection("users").whereField("nickname", isEqualTo: "Nick").getDocuments() { (querySnapshot, err) in if let err = err { print("Error getting documents: \(err)") } else { for document in querySnapshot!.documents { print(document.documentID) } } }

You have to create a UIImageView and add it as subview variable view.In the method func tableView(_:viewForHeaderInSection:) you have to add:let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 30, height: 30)) // el frame seguramente varíe... imageView.image = UIImage(...) // ver desde donde se obtiene la imagen view.addSubview(imageView)
