Thanks! That should help me get started. Is there a guide for when I want to do more advanced stuff with a AGSDynamicLayer subclass?
For example the layer would contain multiple images for different locations, the images might overlap, the images need to be rotated and perhaps it makes sense to adjust their resolution based on the zoom level.
For now I just need to make a proof of concept with a single image, so I can do that with the example in Github you pointed me to.
