Store CLLocationCoordinate2D to NSUserDefaults

Question

I am new to iphone development, and i want to store CLLocationCoordinate2D object to NSUserDefaults. I am Trying

    [defaults setObject:location forKey:@"userLocation"];

But it gives error 'Sending CLLocationCoordinate2D to parameter of incompatible type id'

So How to store CLLocationCoordinate2D into NSUserDefaults? Thanks.

Answer 1

As pdrcabrod said,

"A default object must be a property list, that is, an instance of NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary."

I use this to store,

    NSNumber *lat = [NSNumber numberWithDouble:location.latitude];
    NSNumber *lon = [NSNumber numberWithDouble:location.longitude];
    NSDictionary *userLocation=@{@"lat":lat,@"long":lon};

    [[NSUserDefaults standardUserDefaults] setObject:userLocation forKey:@"userLocation"];
    [[NSUserDefaults standardUserDefaults] synchronize];

And access using,

    NSDictionary *userLoc=[[NSUserDefaults standardUserDefaults] objectForKey:@"userLocation"];
    NSLog(@"lat %@",[userLoc objectForKey:@"lat"]);
    NSLog(@"long %@",[userLoc objectForKey:@"long"]);
