关于iOS uinavigationcontroller及Uitabbarcontroller知识的梳理
一、导航UINavigationController
导航到一个controller：
[navigateController pushViewController:loginView animated:YES];
返回到上页的代码：
[self.navigationController popViewControllerAnimated:YES];
返回到根的代码：
[self.navigationController popToRootViewControllerAnimated:<#(BOOL)#>]
返回固定view的代码：
[self.navigationController popToViewController:<#(UIViewController *)#> animated:<#(BOOL)#>:<#(BOOL)#>]
示例代码：
代码例子一
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
LoginViewController *loginView=[[LoginViewController alloc] init];
loginView.title=@"用户登陆";
UINavigationController* navigateController=[[UINavigationController alloc]init];
[navigateController pushViewController:loginView animated:YES];
[self.window addSubview:navigateController.view];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
二、Uitabbarcontroller知识的梳理
代码例子二
-(void) onLogin:(id)sender
{
UITabBarController* tabController=[[UITabBarController alloc]init];
InfoViewController* info=[[InfoViewController alloc]init];
info.title=@"话费查询";
UINavigationController* infoNav=[[UINavigationController alloc]init];
[infoNav pushViewController:info animated:YES];
UINavigationController* indexNav=[[UINavigationController alloc]init];
indexViewController* indexController=[[indexViewController alloc]init];
indexController.title=@"拜佛系统";
[indexNav pushViewController:indexController animated:YES];
tabController.viewControllers=[NSArray arrayWithObjects:indexNav,infoNav, nil];
[self presentModalViewController:tabController animated:YES];
}
代码例子一二的效果图如下：
