我有一个使用TabBar模板的应用程序。在其中一个视图控制器中,我想添加一个uinavigationcontroller。我在.h文件中声明它;无法将UINavigationController以编程方式添加到TabBar应用程序

#import <UIKit/UIKit.h> 
#import "AnotherViewController.h" 

@interface SecondViewController : UIViewController <UINavigationControllerDelegate> { 
    UIButton *UIButton *gotoAnotherView;; 
    AnotherViewController *anotherView; 
    UINavigationController *navigationController; 
} 

@property(nonatomic,retain) UIButton *UIButton *gotoAnotherView;; 
@property(nonatomic,retain) AnotherViewController *anotherView; 
@property(nonatomic,retain) UINavigationController *navigationController; 

-(void)buttonPressed:(id)sender; 

@end 

这是我的.m文件

#import "SecondViewController.h" 


@implementation SecondViewController 

@synthesize navigationController, anotherView, gotoAnotherView; 


-(void)buttonPressed:(id)sender { 

    anotherView = [[AnotherViewController alloc]init]; 
    [navigationController pushViewController:anotherView animated:YES]; 
} 

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib. 
- (void)viewDidLoad 
{ 

    navigationController = [[UINavigationController alloc ]initWithRootViewController:self]; 
    [navigationController.navigationBar setFrame:CGRectMake(0, 0, 320, 44)]; 

    [self.view addSubview:navigationController.navigationBar]; 

    gotoAnotherView = [[UIButton alloc] initWithFrame:CGRectMake(50, 50, 40, 40)]; //kategoributonlari 

    UIImage *image = [UIImage imageNamed:@"1.png"]; 
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; 
    imageView.frame = CGRectMake(110, 5, 100, 20); 
    [self.view addSubview:imageView]; 

    [kategori1 setBackgroundImage:image forState:UIControlStateNormal]; 

    [kategori1 addTarget:self 
       action:@selector(buttonPressed:) 
    forControlEvents:UIControlEventTouchUpInside]; 

    [self.view addSubview:kategori1]; 

    [super viewDidLoad]; 

} 




- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    // Return YES for supported orientations 
    return (interfaceOrientation == UIInterfaceOrientationPortrait); 
} 


- (void)didReceiveMemoryWarning 
{ 
    // Releases the view if it doesn't have a superview. 
    [super didReceiveMemoryWarning]; 

    // Release any cached data, images, etc. that aren't in use. 
} 


- (void)viewDidUnload 
{ 
    [super viewDidUnload]; 

    // Release any retained subviews of the main view. 
    // e.g. self.myOutlet = nil; 
} 

但是我可以从该navigationcontroller深入一层导航栏看到(后面会出现按钮),但主要观点仍与我gotoAnotherView相同按钮。

我想我可能不会让navigationcontroller控制整个视图。我会很感激任何帮助。

谢谢。

为什么性能也声明为成员变量? –

而不是尝试在代码中执行此操作,编辑主窗口的XIB(使用UITabBarController)。从库中拖出一个UINavigationController到标签栏。这将使用UINavigationController为您创建一个新的酒吧项目。选择嵌套在新UINavigationController中的UIViewController,然后在Identity选项卡上将Class设置为视图控制器,并在Attributes选项卡上指定要加载的nib文件的名称。

很酷。我讨厌使用IB,但至少在主布局上,我可以使用它。 =) –

@Hasan你真的应该读这篇[与Aaron Hillegass的访谈](http://www.informit.com/articles/article.aspx?p=1220319)。特别是问题的答案**您认为新的Mac开发人员来自Windows,Java甚至传统C++ GUI工具包的最常见误解是什么?**使用链锯。 – SSteve

您不需要使用IB。您可以在代码中设置所有内容。首先创建视图控制器tab1ViewController,tab2ViewController等,然后用tab1ViewController等的根视图控制器创建导航控制器,然后将这些控制器添加到标签栏控制器。

这里有一个例子:

UINavigationController *tab1NavigationController = [[UINavigationController alloc] initWithRootViewController:tab1ViewController]; 
UINavigationController *tab2NavigationController = [[UINavigationController alloc] initWithRootViewController:tab2ViewController]; 
UITabBarController rootViewController = [[UITabBarController alloc] init]; 
rootViewController.viewControllers = [NSArray arrayWithObjects:tab1NavigationController, tab2NavigationController, nil]; 
[tab1NavigationController release]; 
[tab2NavigationController release];
