Detect UILabel text change in swift

Question

Is there a way to get notified when there is a change in a UILabel\'s text or would I be better off using a UITextField with userInteractionE

Answer 1

Create a class that inherits from UILabel. Such as:

class YourLabel: UILabel {

    override var text: String? {
        didSet {
            if let text = text {
                println("Text changed.")
            } else {
                println("Text not changed.")
            }
        }
    }
}

Create a outlet of this class for your object.

@IBOutlet weak var label: YourLabel!
label.text = "abc"
