LFHeatMap generates a UIImage containing the heat map based on a point/value array. The generated image can be overlayed on any view, and there is included functionality for generating heat maps specifically for map views based on CLLocationObjects corresponding to the map coordinates.

Here’s an image from the readme that shows the included demo plotting the magnitudes of the 2011 Virginia Earthquake.

You can find LFHeatMap on Github here.
