How to create UINavigationBar drop shadow

Question

Would like to know create drop shadow for UINavigationbar. I tried to create custom navigation bar background with drop shadow, but the drop shadow cover the background view

Answer 1

I stick the shadow drawing code into a function to keep loadView clean. You could pass in the object you want to draw the shadow on if you wanted all your shadows consistent.

- (void)loadView
{
    self.view = [[UIView alloc] init];
    self.view.backgroundColor = [UIColor whiteColor];

    [self drawShadow];
}


- (void)drawShadow
{
    self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
    self.navigationController.navigationBar.layer.shadowOpacity = 0.3;
    self.navigationController.navigationBar.layer.shadowOffset = CGSizeMake(0, 0);
    self.navigationController.navigationBar.layer.shadowRadius = 15;
    self.navigationController.navigationBar.layer.masksToBounds = NO;
}
