Hi everyone, I need help with SwiftUI.
My goal: I have a macOS app built, and I want to...
- Have a button to open the emoji picker (managed this)
- When the user selects an emoji, intercept that value with
NSResponder - Then use it on my Button label
The code below is a simplification. I need help: How can I intercept the value from the NSResponder and print it?
import SwiftUI
import AppKit
struct ContentView: View {
private let emojiResponder = EmojiResponder()
var body: some View {
Button {
// open the emoji picker
if let window = NSApplication.shared.keyWindow {
window.makeFirstResponder(emojiResponder)
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
NSApp.orderFrontCharacterPalette(nil)
}
}
} label: {
Text("Emoji?")
}
.onAppear {
emojiResponder.onEmojiSelected = { selectedEmoji in
print(selectedEmoji)
}
}
}
}
// Custom Emoji NSResponder
class EmojiResponder: NSResponder {
var onEmojiSelected: ((String) -> Void)?
// use insertTest method from NSResponder
// I assume this allows me to get the input
override func insertText(_ insertString: Any) {
guard let selectedEmoji = insertString as? String else { return }
onEmojiSelected?(selectedEmoji)
print(selectedEmoji)
}
}
Can anyone give me a pointer on how to solve this?
What happens now:
- The emoji picker is opened, but nothing happens after I select an emoji
