Add text to speak before announcing label's text

Question

I have a label in my app that the user should be able to tap on with VoiceOver enabled to have it speak the text of that label. However, I want it to always say something before it reads the label's text. I tried to set the accessibilityLabel via self.displayLabel.accessibilityLabel = "my text here" + self.displayLabel.text! but this results in it always being set to the label's original text value which is always changing in this app.

How can I add text to announce just before the label's content, ensuring it will always speak the label's current text contents?

Update it each time the label text changes (and consider posting an announcement or layout change notification) — Wain, Dec 04 '14 at 07:39

Override the accessibilityLabel property in the UILabel subclass to return whatever you'd like.

override var accessibilityLabel: String! {
    get {
        return "my text here" + "," + self.text!
    }
    set { }
}

You may want to post an announcement each time the text changes to inform VO users the value has changed.

Isn't it 'super.accessibilityLabel = newValue' in the setter instead? That code seems to go in a recursive infinite loop. – John Difool Jun 07 '15 at 16:21
@JohnDifool You are right. You can leave the setter empty. Thanks – Jordan H Jun 08 '15 at 01:13
