I am looking for a small example showing how the NSMeasurementFormatter works.
I would like a switch that toggles between "Imperial" and "Metric" Units and 3 measurements that the user types in:
Density in lb/ft^3 or kg/m^3
Speed in ft/min or m/s
Area in in^2 or mm^2
I am hoping the user can type these three values in and the switch between Imperial and metric changes their values and the units displayed.
Example can be in OS X or iOS.
