圍繞視圖繪製陰影減慢我的轉變，CALayer的，IOS

MyViewControllerB.xib包含圍繞視圖繪製陰影減慢我的轉變，CALayer的，IOS

view(UIView) 
    | 
    |__image (UIImageView) 
    | 
    |__view (UIView) 
    | 
    |__text (UITextView) 
    | 
    |__view (UIView) (shadow is adding at here)

然後我在底部如下

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    [self.bottomView.layer setMasksToBounds:NO]; 
    self.bottomView.layer.shadowColor = [UIColor blackColor].CGColor; 
    self.bottomView.layer.shadowRadius = 5; 
    self.bottomView.layer.shadowOpacity = 1; 
    self.bottomView.layer.shadowOffset = CGSizeMake(0 , 0); 
}

當我加入視圖四周陰影我在做MyViewControllerA上的pushViewController: animated:：

@implementation MyViewControllerA 
    MyViewControllerB *controller  = [[MyViewControllerB alloc] initWithNibName:@"MyViewControllerB" bundle:nil]; 
    [self.navigationController pushViewController:controller animated:YES];

那麼過渡不是sm根本就不是。但是，如果刪除用於繪製陰影的代碼塊，則轉換過程與往常一樣平滑。

您對此問題有任何想法。謝謝
