I am creating a library which contains an API for setting the current location based off some value collected by the GPS. I want to store this location in my class and later, change the behavior of my library if it is set.

What I had in mind was:

@interface myLib
{
@property (nonatomic, retain) CLLocationCoordinate2D *location;
}

@implementation myLib
{
@synthesize location = _location;

- (void)setLocation:(CLLocationCoordinate2D *)loc {
location = loc;
}

- (void)someFunc {
 if (location != nil) ...  
}

}

However, retain isn't a valid property for a CLLocationCoordinate2D object.

So, what is the proper way to save CLLocationCoordinate2D for later use w/o wasting memory?

Thanks in advance!
