InfoWindow for iOS Google Maps, which varies depending on the size of the subheadings

Question

I am trying to autostart InfoWindow. Corrected representations seem fairly easy with XIB, for example.

I would like to automatically resize the view so that the width and height are relative to the size of the label and possibly any other subheadings that are added, for example. Images.

I tried this approach from SO without success, but my fault is that it is possible on Friday ..
