Push another View in UINavigationController?
提问by ftwhere
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/
如何使用导航控制器中的按钮推送视图？我试着按照这个例子：http: //www.cimgf.com/2009/06/25/uitabbarcontroller-with-uinavigationcontroller-using-interface-builder/
This is exactly what I need, I have an UITabBarControllerwith 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?
这正是我所需要的，我有一个UITabBarController带有 4 个标签的标签，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 - 这是一个简单的UIView. 它不起作用，我也尝试使用以编程方式创建的按钮，但没有任何反应。任何指针？
Here's the code I have
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;
}
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 Builderor programmatically ) act like they're not linked to any method.
我已经尝试了你们的建议，但仍然没有，按钮（无论它们是在中创建Interface Builder还是以编程方式创建）表现得好像它们没有链接到任何方法。

Put this where you want to create the button: (e.g. the Root VC's -viewDidLoad)
把它放在你想创建按钮的地方：（例如 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:
并实现这个方法：
- (void)didPressButton:(UIButton *)sender
{
UIViewController *viewController = [[[UIViewController alloc] init] autorelease];
[self.navigationController pushViewController:viewController animated:YES];
}

If you use storyboard, create a segue manually
如果您使用故事板，请手动创建一个 segue
On storyboard:
在故事板上：
- click on the view
- then on the right sidebar top menu select the "Show the connections inspector"
- in the "Triggered Segues", click and drag the "manual" trigger to the view you want to push
- chose "push" in the pop menu that will appear
- 点击查看
- 然后在右侧边栏顶部菜单上选择“显示连接检查器”
- 在“Triggered Segues”中，单击“手动”触发器并将其拖动到要推送的视图
- 在出现的弹出菜单中选择“push”
it will create a segue, now select the segue and give it a identifier
它将创建一个segue，现在选择segue并给它一个标识符
Now you can use the code:
现在您可以使用以下代码：
-(IBAction)doneAction:(id)sender
{
[self performSegueWithIdentifier:@"identifier" sender:self ];
}
now you can wire the action to your button
现在您可以将操作连接到您的按钮

To push a view to the navigation controller just do:
要将视图推送到导航控制器，只需执行以下操作：
YourController *childController = [[YourController alloc] initWithNibName:@"YourControllerView" bundle:NSBundle.mainBundle];
[self.navigationController pushViewController:childController animated:YES];
[childController release];
Now if you want it to happen when pressing a button, add a button to your nib file and connect it to a IBActionmethod on Touch Up Inside event.
现在，如果您希望在按下按钮时发生这种情况，请在您的 nib 文件中添加一个按钮并将其连接到IBActionTouch Up Inside 事件的方法。
