How do I use a Button in a swiftUI view? The view will just contain the Button and some Texts. When the button is tapped it will execute a function that will change the words in the Texts and then wait for another Button tap and repeat. I could readily do it with UIKit but with swiftUI a Button seems to be more involved than I expected.

Answer 1

So the way you can do it is to create a custom button that you can use on many views.
/// Custom button that can be used in any view
struct CustomButton: View {
// This is the custom method called from other views
var action: () -> ()
var body: some View {
VStack {
Button(action: { self.action() }) {
Text("Tap me")
}
}
}
}
And then, you can use it this way on your main view and change the text for example. You can add anything you want in the changeMyText method.
// Your main view
struct ContentView: View {
// Keep track of the change of a tap
#State private var buttonTapped = false
var body: some View {
VStack(spacing: 50) {
Text(buttonTapped ? "My second Text" : "My first text")
// Declare your custom button with desired functions
CustomButton(action: { self.changeMytext() })
}
}
// Method where you perform whatever you need
func changeMytext() {
self.buttonTapped.toggle()
}
}
