我尝试使用带有导航栏的“选项卡式应用程序”.使用默认标签栏工作正常,但我只是无法gat导航栏.我找到了一些关于推动导航栏和类似东西的东西,但我发现的所有东西都是几年前的,所以不要帮助我.最近的东西已经过时,因为iOS5和
Xcode的新版本..
任何人都能指出我正确的方向来结合一个来解决这个问题吗？
请记住以下事实：
>我正在为iOS5开发
>我正在使用Xcode 4.2
解决方法
以下是如何以编程方式实现它.
在[appName] -Info.plist中删除对主xib的引用
在main.m中,加载您的委托：
int retVal = UIApplicationMain(argc,argv,nil,@"myAppDelegate");
在app delegate中,加载tabBar,导航控制器和navigationController中的视图.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// create window since nib is not.
CGRect windowBounds = [[UIScreen mainScreen] applicationFrame];
windowBounds.origin.y = 0.0;
[self setWindow:[[UIWindow alloc] initWithFrame:windowBounds]];
// View Controllers for tabController (one viewController per tab)
NSMutableArray *viewControllers = [[NSMutableArray alloc] init];
// first tab has view controller in navigation controller
FirstView *firstView = [[FirstView alloc] initWithNibName:@"FirstView" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:firstView];
[viewControllers addObject:navController];
SecondView *secondView = [[SecondView alloc] initWithNibName:@"SecondView" bundle:nil];
[viewControllers addObject:secondView];
// create the tab controller and add the view controllers
UITabBarController *tabController = [[UITabBarController alloc] init];
[tabController setViewControllers:viewControllers];
// add tabbar and show
[[self window] addSubview:[tabController view]];
[self.window makeKeyAndVisible];
return YES;
}
