ios项目常用模板框架之UITabBar+Nav

最后更新于:2022-04-01 09:45:20

在实际的项目开发中总是有几个比较常见的模板,小编这几天给大伙出几期常用模板的博客,希望大家多提宝贵的意见! 这几个月最常用的莫过于Nav+UITabBar模板了;在实际的项目中,我比较侧重于纯代码,比较不喜欢拖控件,至于利弊在这里不多说了,言归正传。 首先在AppDelegate.m中创建一个空白布景: ~~~ self.window=[[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]]; 初始化UITabBarController self.tabBarController=[[UITabBarController alloc]init]; ~~~ 创建两个视图控制器: ~~~ FirstViewController *one=[[FirstViewController alloc]init]; SecondViewController *second=[[SecondViewController alloc]init]; ~~~ 创建两个导航控制器并 让这两个导航控制器控制好各自的视图控制器: ~~~ UINavigationController *navFirst=[[UINavigationController alloc]initWithRootViewController:one]; UINavigationController *navSecond=[[UINavigationController alloc]initWithRootViewController:second]; ~~~ 让tabBarController包含这两个导航控制器: ~~~ [self.tabBarController addChildViewController:navFirst]; [self.tabBarController addChildViewController:navSecond]; ~~~ 对各自的视图控制器进行细腻化的定制: ~~~ one.title=@”联系人”; one.tabBarItem=[[UITabBarItem alloc]initWithTitle:@”one” image:[UIImage imageNamed:@”“] selectedImage:nil]; second.title=@”收藏”; second.tabBarItem=[[UITabBarItem alloc]initWithTitle:@”second” image:nil selectedImage:nil]; ~~~ 设置改空白布景上的主视图为:tabBarController: ` [self.tabBarController addChildViewController:navSecond]; ` 修改布景为红色: `self.window.backgroundColor=[UIColor redColor]; ` 显示布景: ` [self.window makeKeyAndVisible]; ` 在FirstViewController中创建二级页面 创建导航栏: `UIBarButtonItem *rightButton=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemSearch target:self action:@selector(selectRightAction:) ]; ` 实现跳转方法: ~~~ -(void)selectRightAction:(id)sender { BackViewController *backButton; backButton=[[BackViewController alloc]initWithNibName:@"BackViewController" bundle:nil]; backButton.title=@"第二视图层"; [self.navigationController pushViewController:backButton animated:NO]; } ~~~ 代码示例下载地址:[http://download.csdn.net/detail/it_ds/8568545](http://download.csdn.net/detail/it_ds/8568545)
