这可能是一个愚蠢的问题,但我以编程方式将UINavigationController添加到我的应用程序中。如果可能的话,我想把它添加到我所有窗口的顶部,除了第一个.xib。也许只是将它隐藏在我的第一个.xib上。有可能做到这一点吗?我想起了我的第一个.xib文件,它打开了我的应用程序的其余部分,就像一个封面页面,我宁愿那个蓝色栏没有出现在那个顶部。我希望我能给你看图片,但还没有足够的代表。谢谢!
以下是我认为可以帮助我使用后栏提供每个应用页面的代码:
#import "McCormick_TaylorViewController.h"
@implementation McCormick_TaylorAppDelegate
@synthesize window = _window;
@synthesize viewController = _viewController;
- (void)dealloc
{
[_window release];
[_viewController release];
[super dealloc];
}
- (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 = [[[McCormick_TaylorViewController alloc]
initWithNibName:@"McCormick_TaylorViewController" bundle:nil] autorelease];
UINavigationController * navController = [[UINavigationController alloc]
initWithRootViewController:self.viewController];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}

在你的McCormick_TaylorViewController的viewWillApper:
方法
只使用下面的代码...
[self.navigationController setNavigationBarHidden:NO animated:YES];
并在导航栏中的其他视图控制器中显示然后在另一个viewController的viewWillAppear中使用波纹管代码..
[self.navigationController setNavigationBarHidden:NO animated:NO];

使用此方法:
- (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 = [[[McCormick_TaylorViewController alloc]
initWithNibName:@"McCormick_TaylorViewController" bundle:nil] autorelease];
UINavigationController * navController = [[UINavigationController alloc]
initWithRootViewController:self.viewController];
[navController.navigationBar setHiden:YES]; // hides navigation bar
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
