Single View Application 中使用 UINavigationController

首先通过File - New - New Project 创建一个Single View Application

项目创建之后, 再通添加文件 - Coca Touch - UIViewController 创建MainViewController, 其中xib项需要选中.

同样的方法创建一个SubViewController.

切换回AppDelegate.m 添加

#import "MainViewController.h"

然后将didFinishLaunchingWithOptions的方法发为下面的. 主要是定义一个UINavigationController, 然后定义其的rootViewController为MainViewController

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];    // Override point for customization after application launch.    //self.viewController = [[NavViewController alloc] initWithNibName:@"NavViewController" bundle:nil];     //self.window.rootViewController = self.viewController;    self.viewController= [[NavViewController alloc] initWithNibName:@"NavViewController" bundle:nil];     UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.viewController];    [self.window addSubview:nav.view];    [self.window makeKeyAndVisible];    return YES;}

然后, 返回MainViewController, 定义一个button, 定义buttonpressed事件. 

返回nib, 拖一个按钮到window上面, 通过拖拽建立起关联.

-(IBAction)buttonPressed{    self.sub = [[SubNavController alloc] initWithNibName:@"SubNavController" bundle:nil];    [self.navigationController pushViewController:self.sub animated:YES];    [self.sub release];}

此时运行项目, 点击按钮, 就会切换到SubNavController中了~ 上面会显示出"返回"的按钮. 

此外, Navigation拥有下面的属性, 都可以自己定义.

-title

-titleview

-backBarButtonItem

-rightBarButtonItem

-leftBarButtonItem
