How to customize the size of callout for MKAnnotationView?

Question

I'm new to iOS. I need to set the size of the callout 300 * 150, how can I do this?

Answer 1

I've added subview with size I needed.

Answer 2

The size of the callout bubble adjusts according to the text it contains. If you set Title and subtitle as some long text, the callout will adjust according to it.
