add a method to UIImage by category
按类别向 UIImage 添加方法
+ (UIImage *)imageWithColor:(UIColor *)color {
CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return theImage;
}
and just set
并设置
[self.navigationController.navigationBar setShadowImage:[UIImage imageWithColor:[UIColor whiteColor]]];

This is what I did, and seemed to work, it is a further development of this link. I changed the explicit width declaration to a dynamic one, so that it will be the size of the view if you change view size or not:
这就是我所做的，并且似乎有效，这是此链接的进一步发展。我将显式宽度声明更改为动态声明，这样无论您是否更改视图大小，它将是视图的大小：
UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 43, self.view.frame.size.width, 1)];
[overlayView setBackgroundColor:[UIColor whiteColor]];
[navBar addSubview:overlayView]; // navBar is your UINavigationBar instance
[overlayView release];
I found the stuff here: How to remove UINavigatonItem's border line
