在moreNavigationController上的自定义NavigationBar [英] Custom navigationBar on moreNavigationController

问题描述

是否要自定义导航栏，该导航栏出现在UITabBarController的更多"选项卡上，以2像素(不同颜色)的线作为底边框?

Hot to customize navigation bar that appear on "More" tab in UITabBarController to have 2 px line (in different color) as bottom border?

我创建了UINavigationBar的子类，该子类使用该行的绘制覆盖了drawrect:方法，并且适用于前四个选项卡，但更多导航控制器下的选项卡除外.

I created subclass of the UINavigationBar that overrides drawrect: method with drawing of that line, and that works for first four tabs, except tabs that are under more navigation controller.

有帮助吗?

推荐答案

#import <objc/runtime.h>

并动态设置more view controller导航栏的类:

And dynamically set the class of the more view controller's navigation bar:

object_setClass(yourTabBarController.moreNavigationController.navigationBar, 
                [YourNavigationBarSubClass class]);
