How to Plot (show) user location on Image? iOS

Question

So here is task i need to get done on iOS:

Show User's Current Location on an Image like this:

Yes, like this Image!

So few things one will notice as soon as one look at it. Its Tilted. It's headings are Off. You can see horizon..!

Lets say,

• I have location coordinates for corners of this image.
• I have angle at which this image is tilted. (e.g 50°)
• I have heading angle of the image. (e.g -170° North, which means its about 10° South-West, correct me if im wrong.)
• And i have Zoom level on which this image would have been zoomed if it was on Google Maps/Google Earth. (e.g 14 zoom level - out of 20)

But thats the task, i need to show users location on such images. Just like in "Google Earth".

Can anyone give me heads up to accomplish this task?

Thank you everyone. :)
