迅速-MapKit中的自定义注释偏移

Question

I have the following annotation with a callout in the form of a xib file that looks like this:

Current state

I would like to know how to offset the annotation callout so that the origin of the annotation callout is not at the point of the annotation itself, but offset by 10 points on the y axis, so it would be a little bit above the annotation. Is there a way to do this?

Can you help me achieve this? Any help is appreciated, thanks!

Still looking for the solution.

Answer 1

I set it in swift code like this:

class CarAnnotationView: MKAnnotationView {
    override var annotation: MKAnnotation? {
        willSet {
            guard let carAnnotation = newValue as? CarAnnotation else { return }
            self.calloutOffset = CGPoint(x: -5, y: 5)
            ....
        }
    }
}

The important line is:

self.calloutOffset = CGPoint(x: -5, y: 5)

Answer 2

I found the solution for my case, it was just a question of setting the origin of the custom annotationView that I creted from a xib file.

Like so:

newCustomCalloutView.frame.origin.y -= newCustomCalloutView.frame.height + 3

The important part is the + 3 in the line above.
