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。
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.
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];
}
