It just requires a little bit of encoding.

- (IBAction)directions1_click:(id)sender
{
    NSString* address = @"118 Your Address., City, State, ZIPCODE";
    NSString* currentLocation = @"Current Location";
    NSString* url = [NSStringstringWithFormat: @"http://maps.google.com/maps?saddr=%@&daddr=%@",[currentLocation stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],[address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    UIApplication *app = [UIApplicationsharedApplication];
    [app openURL: [NSURL URLWithString: url]];
}
