CLLocationCoordinate2D invalid initializer

I am using CLLocationCoordinate2D in to assign latitude and longitude like this

 CLLocationDegrees latitude = [somelat doubleValue];
 CLLocationDegrees longitude = [somelongi doubleValue];
 CLLocationCoordinate2D coordinate = CLLocationCo开发者_Python百科ordinate2DMake(latitude, longitude);

When i run this code in iPhone simulator its not showing error but wheni run the same application in ios simulator 3.2 that is the iPad simulator its showing me an "Invalid Initializer" error.

How can i resolve this...Please anybody suggest me a solution to this problem

Thanks and regards, Sankar Chandra Bose

CLLocationCoordinate2DMake is available only on iOS 4.0 and later. Do this rather,

CLLocationCoordinate2D coordinate;
coordinate.longitude = longitude;
coordinate.latitude = latitude;

> CLLocationDegrees latitude,   
> CLLocationDegrees longitude)

Parameters

latitude

The latitude for the new coordinate. longitude

The longitude for the new coordinate.
