Deselect the text in a NSTextField

Question

Is there an easy way to deselect an NSTextField after pressing enter?

Answer 1

First you will need to make your view controller the delegate of your text field. Then you override NSControl instance method controlTextDidEndEditing(_:), get your textfield current editor selected range and from the main thread set it back to your textfield:

import Cocoa

class ViewController: NSViewController, NSTextFieldDelegate {
    @IBOutlet weak var textField: NSTextField!
    override func viewDidLoad() {
        super.viewDidLoad()
        textField.delegate = self
    }
    override func controlTextDidEndEditing(_ obj: Notification) {
        if let selectedRange = textField.currentEditor()?.selectedRange {
            DispatchQueue.main.async {
                self.textField.currentEditor()?.selectedRange = selectedRange
            }
        }
    }
}
