I am using apple's Footprint: Indoor Positioning with Core Location I have successfuly implemented it in my iOS application with my custom Floor Plan Image.
now what I want is to zoom in and out this image and i want that my current location pin object on the image should scale according to that and there is no documentation they provide on how to zoom in/out the image of floor plan with the object showing on that image(e.g. user current location pin).
Try to use the newer version of Footprint (v2.0): https://developer.apple.com/library/prerelease/ios/samplecode/footprint/Introduction/Intro.html
with: -Added Swift support -Built-in diagnostic visualizations & annotations for detecting coordinates alignment problems -Uses PDF for better support at multiple device sizes and zoom levels -Uses MKMapView for better rotation and zoom support, as well as native blue dot support -Shows how to handle venue specific regions
