使用tag值找view

albumDetailController.view.frame = CGRectMake((1024-600)/2,768, 600, 500); 


 UIView *bgview = [[UIView alloc] initWithFrame:self.view.frame]; 

 bgview.backgroundColor = [UIColor blackColor]; 

 bgview.alpha = 0; 


 bgview.tag =11001; 

 [self.view addSubview:bgview]; 


UIView *view = (UIView*)[self.view viewWithTag:11001];
