UIBarButtonItem with rounded corners and shadow

Question

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

UIButton *useButton = [UIButton buttonWithType:UIButtonTypeCustom];

Answer 1

    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]];
