如何在不使用storyboard和tableView的情况下在Xcode 4.2中开发NavigationController？

Question

我正在学习Xcode并为IOS开发人员作为实习生工作。我正在使用Xcode 4.2和Lion OS。我的目标操作系统将是ios 3+版本。有人告诉我，使用故事板会给旧版本带来问题。所以我想开发而不使用Storyboard for navigationController。帮助我，因为所有旧的教程都没有帮助，因为xcode版本的变化导致很多错配。 请帮帮我。

Answer 1

要创建导航控制器，请为项目模板选择单一视图应用程序。在AppDelegate.h中，创建UINavigationController的实例。在AppDelegate.m文件中，执行以下操作：

- (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];
    navigationController = [[UINavigationController alloc] initWithRootViewController:(UIViewController*)viewController];
    [window addSubview:navigationController.view];
    [self.window makeKeyAndVisible];
    return YES;
}

这将使基地成为导航控制器。您可以使用

添加其他视图

[self.navigationController pushViewController:newViewController animated:YES];

创建新项目时

有使用故事板的复选标记只是将其从那里移除。然后在你移动之前向前移动。

将此添加到您的AppDelegate，并使用它们。看看会发生什么，你将学习。

@interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>{


}

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) UITabBarController *tabBarController;

@end
//*****************************************//

.m file

 self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    UIViewController *viewController1 = [[Categories alloc] initWithNibName:@"Categories" bundle:nil];
    UIViewController *viewController2 = [[Coupons alloc] initWithNibName:@"Coupons" bundle:nil];
    UIViewController *viewController3 = [[Favourites alloc] initWithNibName:@"Favourites" bundle:nil];
    UIViewController *viewController4 = [[AroundMe alloc] initWithNibName:@"AroundMe" bundle:nil];

    viewController2.title = NSLocalizedString(@"Coupons", @"Coupons");
    viewController2.tabBarItem.image = [UIImage imageNamed:@"coupons.png"];
    viewController3.title = NSLocalizedString(@"Favourites", @"Favourites");
    viewController3.tabBarItem.image = [UIImage imageNamed:@"favourites.png"];


   // UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
    UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
    UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
    UINavigationController *navController3 = [[UINavigationController alloc] initWithRootViewController:viewController3];
    UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:viewController4];
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController1,navController2, navController3, navController4, nil];
    self.window.rootViewController = self.tabBarController;
