Quick intro on how to do ajax on rails. This was simplified from my autocomplete code. In this example the autocomplete is removed and just ajax is presented.
#routes.rb
get 'scraped_episodes_search' => 'scraped_episodes#search'
#scraped_episodes_controller.rb
# used for autocomplete search
def search

Convert MKMapRect to CLRegion aka convert visible region of mapview to CLRegion
- (CLLocationDistance)getDistanceFrom:(CLLocationCoordinate2D)start to:(CLLocationCoordinate2D)end
{
CLLocation *startLoc = [[CLLocation alloc] initWithLatitude:start.latitude longitude:start.longitude];
CLLocation *endLoc = [[CLLocation alloc] initWithLatitude:end.latitude longitude:end.longitude];
CLLocationDistance retVal = [startLoc distanceFromLocation:endLoc];
[startLoc release];
[endLoc release];
return retVal;
