how to create MKCoordinateRegion

How to create MKCoordinateRegion .

    NSString *latitudeString =  [locationString substringToIndex:startRange.location];
    NSString *longtitudeString = [locationString substringWithRange:NSMakeRange(startRange.location+2,((endRange.location-1)-(startRange.location+2)))];
    CLLocationCoordinate2D coord = CLLocationCoordinate2DMake((int)latitudeString, (int)longtitudeString);

    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(coord, 500, 500);`

I get the error "Invalid Region center:+392128672.00000000, +392128704.00000000 span:+0.00448287, -0.01195557"

Solution

  • Remove the type casting. Use below code.

    CLLocationCoordinate2D coord = CLLocationCoordinate2DMake([latitudeString doubleValue], [longtitudeString doubleValue]);
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(coord, 500, 500);
