Custom callout getting dismissed in MKMapView when tapped

I have a map view and a custom callout built from scratch. Everything works fine except that the callout disappears whenever user taps on it.

First, make sure you override pointInside in your custom annotation view to account for the callout:

override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
    if self.bounds.contains(point) {
        return true    
    } else {
        return self.subviews.contains { $0.frame.contains(point) }
    }
}

Then, map view turns out to favour UIButton in a callout and won't dismiss if the tap hits an instance of UIButton. Make sure that you cover the whole callout view with a button (which may or may not do anything when tapped).

You can add subviews into a UIButton, but make sure that they all have isUserInteractionEnabled set to false.
