导航控制器Navigation实现页面跳转

1. 新建一个基于Singal View Application的项目
2. 再新建一个Object-C class 的类，类名为“oneViewController",子类为”UIViewController“，，勾选”with XIB for user interface“
3. 在ViewController.xib文件中拖入一个button按钮，并设置一个按钮点击关联事件，如下图：
4. 编写按钮点击事件的代码，注意要引入oneViewController.h这个头文件：

   - (IBAction)jumpToNext:(UIButton *)sender {
       oneViewController *controller = [[[oneViewController alloc] init] autorelease];
       [self.navigationController pushViewController:controller animated:YES];
   }

   
   
5. 在AppDelegate.m文件中修改如下代码：

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

   
   
6. 点击运行就可以看到效果了。
