  最好的方法是覆盖UINavigationBar中的drawRect并使用自定义图像 .

  以下代码适用于我（在iOS5上测试） . 以下代码围绕主导航栏的左上角/右上角 . 此外，它增加了一个阴影：

  CALayer *capa = [self.navigationController navigationBar].layer;
  [capa setShadowColor: [[UIColor blackColor] CGColor]];
  [capa setShadowOpacity:0.85f];
  [capa setShadowOffset: CGSizeMake(0.0f, 1.5f)];
  [capa setShadowRadius:2.0f];  
  [capa setShouldRasterize:YES];
  
  
  //Round
  CGRect bounds = capa.bounds;
  bounds.size.height += 10.0f;    //I'm reserving enough room for the shadow
  UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:bounds 
                                                 byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight)
                                                       cornerRadii:CGSizeMake(10.0, 10.0)];
  
  CAShapeLayer *maskLayer = [CAShapeLayer layer];
  maskLayer.frame = bounds;
  maskLayer.path = maskPath.CGPath;
  
  [capa addSublayer:maskLayer];
  capa.mask = maskLayer;

  您可能会觉得这很有帮助 . 也许你也可以用CoreAnim / Image进行某种掩饰？我不太了解Core *系列......
