How would you build the simpliest way a MKMapRect with 2 MKMapPoints, assuming that you don\'t know wh开发者_运维百科ere are those points (the first can be lower or upper, more on the left or the righ
I need to get two points that have biggest distance between.开发者_高级运维 The easiest method is to compute distance between each of them, but that solution would have an quadratic complexity.
