title: Shadow UIview and clipsToBounds
body: <p>I would like to set the shadow to my container UIView.
  I use this code to make it:</p>
  
  <pre><code>- (id)initWithCoder:(NSCoder*)aDecoder
  {
      self = [super initWithCoder:aDecoder];
      if (self) {
  
          //-&gt; drop shadow
          [self.layer setShadowColor:[UIColor blackColor].CGColor];
          [self.layer setShadowOpacity:0.6];
          [self.layer setShadowRadius:2.0];
          [self.layer setShadowOffset:CGSizeMake(2.0, 2.0)];
      }
  
      return self;
  }
  </code></pre>
  
  <p>This works well. But, when I use <code>_containerView.clipsToBounds = YES;</code> on this container UIView, I can't see my shadow. Why?</p>
