[\_deepAR setLicenseKey:@“ioskey”];  
#else  
[\_deepAR setLicenseKey:@“mackey”];  
#endif  
\_deepAR.delegate = self;  
[\_deepAR changeLiveMode:NO];  
[\_deepAR initializeOffscreenWithWidth:640 height:480];  
//\_arview = (ARView\*)[\_deepAR createARViewWithFrame:CGRectMake(0.0, 0.0, 1.0, 1.0)];  
\_deepAREffectString = [[NSBundle mainBundle] pathForResource:@“galaxy\_background.deepar” ofType:@“”];
