推荐答案

我认为没有办法改变导航颜色的边框颜色， UINavigationBar 的 tintColor 属性除外。

I do not think there is a method to change the border color of the navigation color, other than the tintColor property of the UINavigationBar.

我建议您创建一个边框大小的UIView并将其放在导航栏下面/将其添加为 subView 。

I would suggest that you create a UIView of that border size and place it below the navigation bar / add it as a subView.

UIView *navBorder = [[UIView alloc] initWithFrame:CGRectMake(0,navigationBar.frame.size.height-1,navigationBar.frame.size.width, 1)]; 

// Change the frame size to suit yours //

[navBorder setBackgroundColor:[UIColor colorWithWhite:200.0f/255.f alpha:0.8f]];
[navBorder setOpaque:YES];
[navigationBar addSubview:navBorder];
[navBorder release];
