在UINavigationController中推送另一个View？

Question

如何使用导航控制器中的按钮推送视图？我试着效仿这个例子:http: //www.cimgf.com/2009/06/25/uitabbarcontroller-with-uinavigationcontroller-using-interface-builder/

这正是我需要的,我有一个UITabBarController4个标签,其中一个是UINavigationController.我想从第一个视图推送包含导航控制器的视图 - 这很简单UIView.它不起作用,我尝试使用以编程方式创建的按钮,没有任何反应.有什么指针吗？

这是我的代码

@interface HomeViewController : UIViewController {

}

-(IBAction)pushViewController:(id)sender;

@end

---

#import "HomeViewController.h"
#import "NewViewController.h"

@implementation HomeViewController

-(IBAction)pushViewController:(id)sender {
        NewViewController *controller = [[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil];
    [[self navigationController] pushViewController:controller animated:YES];
    [controller release], controller = nil;
}

我已经尝试过你们建议但仍然没有,按钮(无论是创建Interface Builder还是编程)都表现得像是没有链接到任何方法.

把它放在你想要创建按钮的位置:(例如根VC -viewDidLoad)

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(100.0, 100.0, 100.0, 40.0);
[button setTitle:@"Press" forState:UIControlStateNormal];
[viewController.view addSubview:button];

[button addTarget:self action:@selector(didPressButton:) forControlEvents:UIControlEventTouchUpInside];

并实现此方法:

- (void)didPressButton:(UIButton *)sender
{
    UIViewController *viewController = [[[UIViewController alloc] init] autorelease];
    [self.navigationController pushViewController:viewController animated:YES];
}
