在UINavigationController中推送另一个View？ [英] Push another View in UINavigationController?

问题描述

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，我有一个带有4个标签的 UITabBarController ，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 - 这是一个简单的 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。任何指针？

这是我的代码

  @interface HomeViewController ：UIViewController {
 
} 
 
  - （IBAction）pushViewController：（id）sender; 
 
 @end 
 
 --- 
 
 #importHomeViewController.h
 #importNewViewController.h
 
 @implementation HomeViewController 
 
  - （IBAction）pushViewController：（id）sender {
 NewViewController * controller = [[NewViewController alloc] initWithNibName：@NewViewControllerbundle：nil] ; 
 [[self navigationController] pushViewController：controller animated：YES]; 
 [控制器发布]，controller = nil; 
}

我已经尝试过你们建议但仍然没有，按钮（是否在界面生成器中创建或以编程方式）表示它们没有链接到任何方法。

解决方案

将它放在你想要创建按钮的位置:(例如Root VC的 -viewDidLoad ）

  UIButton * button = [UIButton buttonWithType：UIButtonTypeRoundedRect]; 
 button.frame = CGRectMake（100.0,100.0,100.0,40.0）; 
 [button setTitle：@按forState：UIControlStateNormal]; 
 [viewController.view addSubview：button]; 
 
 [button addTarget：self action：@selector（didPressButton :) forControlEvents：UIControlEventTouchUpInside]; 
  

并实施此方法：

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

How to push a view using a button in a navigation controller? I tried to follow this example: http://www.cimgf.com/2009/06/25/uitabbarcontroller-with-uinavigationcontroller-using-interface-builder/

This is exactly what I need, I have an UITabBarController with 4 tabs and one of them is an UINavigationController. I want to push that view containing the navigation controller from the first view- which is a simple UIView. It doesn't work, I tried also with a programmatically created button and nothing happens. Any pointers?

Here's the code I have

@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;
}

Here is also the screenshot with the connections http://imageshack.us/photo/my-images/847/screenshot20110719at620.png/

I've tried what you guys suggested and still nothing, the buttons( whether they are created in Interface Builder or programmatically ) act like they're not linked to any method.

解决方案

Put this where you want to create the button: (e.g. the Root VC's -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];

And implement this method:

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