iOS 成长之路之 控制器

iOS 常用控制器  

 UINavigationController 导航栏控制器

为界面添加导航栏

     ViewController *view = [[ViewController alloc]init];

    UINavigationController *viewNA = [[UINavigationController alloc]initWithRootViewController:view];

    self.window.rootViewController = viewNA;

隐藏导航栏

 self.navigationController.navigationBarHidden = YES;

 

 UITabBarController tabbar控制器

tabbar的实现（iOS自带）

 UITabBarController *_tabbarVC = [[UITabBarController alloc]init];

             MainViewController *Vc = [[MainViewController alloc]init];

              UINavigationController *NaVCmain = [[UINavigationController alloc]initWithRootViewController:Vc];

            NSArray *collerarr = [NSArray arrayWithObjects:NaVCmain, nil];

            _tabbarVC.viewControllers = collerarr;

            NaVCmain.title = @"货单";

           [self.navigationController pushViewController:_tabbarVC animated:YES];

跳转时隐藏tabbar  back后恢复

self.hidesBottomBarWhenPushed=YES;

    NextViewController *next=[[NextViewController alloc]init];

    [self.navigationController pushViewController:next animated:YES];

    self.hidesBottomBarWhenPushed=NO;
