UINavigationController和UITabBarController合用

开发环境：Xcode4.5

很多时候我们创建一个基于UITabBarController的application以后还希望能够在每个tab view都可以实现导航控制，即添加一个UINavigationController来实现tabview内部的view之间的切换,这即是本文所要介绍的。

一、创建一个 Tabbed Application.默认创建的是带有两个Tab的工程。

二、在AppDelegate.h里面添加

@property (strong, nonatomic) UINavigationController *NaviView1Controller;@property (strong, nonatomic) UINavigationController *NaviView2Controller;

三、修改AppDelegate.m文件的didFinishLaunchingWithOptions函数，在这里我们设置相应的UINavigationController.

修改前：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];    // Override point for customization after application launch.    UIViewController *viewController1 = [[[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] autorelease];    UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil] autorelease];    self.tabBarController = [[[UITabBarController alloc] init] autorelease];    self.tabBarController.viewControllers = @[viewController1, viewController2];    self.window.rootViewController = self.tabBarController;    [self.window makeKeyAndVisible];    return YES;}

修改后：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];    // Override point for customization after application launch.    UIViewController *viewController1 = [[[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] autorelease];    viewController1.title = @"View1";    self.NaviView1Controller = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease];    UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil] autorelease];    viewController2.title = @"View2";    self.NaviView2Controller = [[[UINavigationController alloc] initWithRootViewController:viewController2] autorelease];    self.tabBarController = [[[UITabBarController alloc] init] autorelease];        self.tabBarController.viewControllers = @[self.NaviView1Controller, self.NaviView2Controller];        self.window.rootViewController = self.tabBarController;    [self.window makeKeyAndVisible];    return YES;}

运行一下程序，可以看到每个Tab view都自动多了一个NavigationBar在顶部。

三、添加两个新的View测试NavigationController。

1. 创建Test1ViewController类，以及对应的xib文件。

2. 创建Test2ViewController类，以及对应的xib文件。

3. 如果你的iPhone iOS版本低于6.0，在xib的设置里需要勾掉autolayout选项。

四、在Tab view 1的xib文件里添加一个按钮，并设置相应的IBOutlet, IBAction.如下图：

五、编写代码逻辑。

在FirstViewController.m中。编写函数gotoTest1View

- (IBAction)gotoTest1View:(id)sender {    Test1ViewController *SRDVController = [[Test1ViewController alloc]init];    [self.navigationController pushViewController:SRDVController animated:YES];    [SRDVController release];}

同理可以测试，Test2ViewController.不再赘述。
