UIBarButtonItem with rounded corners and shadow

Question

I want to have rounded corners and shadow on a UIBarButtonItem.

UIButton *useButton = [UIButton buttonWithType:UIButtonTypeCustom];

Then I try to set shadow and rounded corners:

useButton.layer.masksToBounds = NO;
useButton.layer.cornerRadius = 4;
useButton.layer.shadowOffset = CGSizeMake(0, 1.5);
useButton.layer.shadowRadius = 0.5;
useButton.layer.shadowOpacity = 1.0;
useButton.layer.shadowColor = [BSTCMColorUtility colorFromHexString:@"#AFAFAF"].CGColor;

Finally I make the UIBarButtonItem:

UIBarButtonItem *useItem = [[UIBarButtonItem alloc] initWithCustomView:useButton];
[self.navigationItem setRightBarButtonItems:@[useItem]];

I get no rounded corners, but I do get the shadow.

If I add:

useButton.clipsToBounds = YES;

And/or:

useButton.layer.masksToBounds = YES;

I get rounded corners, but no shadow. So I thought that I would try to add a sublayer.

CALayer *useButtonShadowLayer = [CALayer new];
useButtonShadowLayer.frame = useButton.frame;
useButtonShadowLayer.cornerRadius = 4;
useButtonShadowLayer.backgroundColor = [UIColor whiteColor].CGColor;
useButtonShadowLayer.shadowOffset = CGSizeMake(0, 1.5);
useButtonShadowLayer.shadowRadius = 0.5;
useButtonShadowLayer.shadowOpacity = 1.0;
useButtonShadowLayer.shadowColor = [BSTCMColorUtility colorFromHexString:@"#AFAFAF"].CGColor;

useButton.layer.cornerRadius = 4;
useButton.layer.masksToBounds = YES;

UIView *parent = useButton.superview;
[parent.layer insertSublayer:useButtonShadowLayer below:useButton.layer];

It doesn't seem to work, I see no shadow. I get rounded corners tho.

Isn't possible to have rounded corners AND shadow on a UIBarButtonItem/UIButton?

Try this Updated code :

UIButton *useButton = [UIButton buttonWithType:UIButtonTypeCustom];
useButton.frame = CGRectMake(100, 430, 100, 40);
useButton.layer.masksToBounds = NO;
useButton.layer.cornerRadius = 10;
useButton.layer.shadowOffset = CGSizeMake(1.5, 1.5);
useButton.layer.shadowRadius = 0.5;
useButton.layer.shadowOpacity = 1.0;
useButton.layer.shadowColor = [UIColor blackColor].CGColor;
useButton.backgroundColor = [UIColor redColor];

UIBarButtonItem *useItem = [[UIBarButtonItem alloc] initWithCustomView:useButton];
[self.navigationItem setRightBarButtonItems:@[useItem]];

    UIButton *useButton = [UIButton buttonWithType:UIButtonTypeCustom];
    useButton.frame = CGRectMake(0, 0, 60, 30);
    useButton.backgroundColor = [UIColor redColor];
    useButton.layer.masksToBounds = NO;
    useButton.layer.cornerRadius = 4;
    useButton.layer.shadowOffset = CGSizeMake(0, 1.5);
    useButton.layer.shadowRadius = 5;
    useButton.layer.shadowOpacity = 1.0;
//    useButton.layer.shadowColor = [UIColor blackColor].CGColor;
    useButton.layer.borderColor = [UIColor blackColor].CGColor;
    [self.view addSubview:useButton];

    UIBarButtonItem *useItem = [[UIBarButtonItem alloc] initWithCustomView:useButton];
    [self.navigationItem setRightBarButtonItems:@[useItem]];
