如何使用按钮触摸内部事件，从一个视图控制器导航到另一个视图控制器？

更多信息

我在示例项目中尝试的步骤是：

创建示例单一视图应用程序。
添加新文件 - ＆gt; Objective-C Class with XIB for user interface（ViewController2）。
在ViewController.xib中添加一个按钮，然后控制单击ViewController.h按钮以创建内部补充事件。

转到ViewController.m中新制作的IBAction并将其更改为此...

- (IBAction)GoToNext:(id)sender 
{
    ViewController2 *vc2 = [[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:nil];

    [[self navigationController] pushViewController:vc2 animated:YES];
}

代码运行没有错误，我使用NSLog测试了按钮的功能。但是它仍然没有导航到第二个视图控制器。任何帮助将不胜感激。

 **Push**

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("NewsDetailsVCID") as NewsDetailsViewController 
 vc.newsObj = newsObj
 navigationController?.pushViewController(vc,
 animated: true)

或更安全

  if let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "NewsDetailsVCID") as? NewsDetailsViewController {
        viewController.newsObj = newsObj
        if let navigator = navigationController {
            navigator.pushViewController(viewController, animated: true)
        }

   let storyboard = UIStoryboard(name: "Main", bundle: nil)
   let vc = self.storyboard?.instantiateViewControllerWithIdentifier("NewsDetailsVCID") as! NewsDetailsViewController
      vc.newsObj = newsObj
           present(vc!, animated: true, completion: nil)

   if let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "NewsDetailsVCID") as? NewsDetailsViewController

    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController"

//Appdelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    let navigat = UINavigationController()
    let vcw = ViewController(nibName: "ViewController", bundle: nil)

    // Push the vcw  to the navigat
    navigat.pushViewController(vcw, animated: false)

    // Set the window’s root view controller
    self.window!.rootViewController = navigat

    // Present the window
    self.window!.makeKeyAndVisible()

    self.navigationController.pushViewController(ViewController2, animated: true)

Answer 2

    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"storyBoardName" bundle:nil];
    MemberDetailsViewController* controller = [storyboard instantiateViewControllerWithIdentifier:@"viewControllerIdentiferInStoryBoard"];
[self.navigationController pushViewController:viewControllerName animated:YES];

斯威夫特4：

let storyBoard = UIStoryboard(name: "storyBoardName", bundle:nil)
let memberDetailsViewController = storyBoard.instantiateViewController(withIdentifier: "viewControllerIdentiferInStoryBoard") as! MemberDetailsViewController
self.navigationController?.pushViewController(memberDetailsViewController, animated:true)

Answer 3

对于 Swift ，请使用以下代码：

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window!.backgroundColor = UIColor.whiteColor()

    // Create a nav/vc pair using the custom ViewController class

    let nav = UINavigationController()
    let vc = NextViewController(nibName: "NextViewController", bundle: nil)

    // Push the vc onto the nav
    nav.pushViewController(vc, animated: false)

    // Set the window’s root view controller
    self.window!.rootViewController = nav

    // Present the window
    self.window!.makeKeyAndVisible()
    return true

}

的ViewController：

 @IBAction func Next(sender : AnyObject)
{
    let nextViewController = DurationDel(nibName: "DurationDel", bundle: nil)

    self.navigationController.pushViewController(nextViewController, animated: true)
}

Answer 4

使用此代码导航下一个viewcontroller，如果您使用的是storyboard，请按照以下代码进行操作，

UIStoryboard *board;

if (!self.storyboard)
{
    board = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
}
else
{
    board = self.storyboard;
}

ViewController *View = [board instantiateViewControllerWithIdentifier:@"yourstoryboardname"];
[self.navigationController pushViewController:View animated:YES];

Answer 5

在按钮操作（Swift 3.0.1）中使用此代码：

let vc = self.storyboard?.instantiateViewController(
    withIdentifier: "YourSecondVCIdentifier") as! SecondVC

navigationController?.pushViewController(vc, animated: true)

Answer 6

UINavigationController不会自动显示在UIViewController中。

这是您应该在Interface Builder中看到的内容。文件所有者具有导航控制器的视图出口，并且从导航控制器出口到实际视图;

Interface Builder

Answer 7

这很完美：

PD：请记住导入目标VC：

#import "DestinationVCName.h"

    - (IBAction)NameOfTheAction:(id)sender 
{
       DestinationVCName *destinationvcname = [self.storyboard instantiateViewControllerWithIdentifier:@"DestinationVCName"];
    [self presentViewController:destinationvcname animated:YES completion:nil];
}

Answer 8

-  (void) loginButton:(FBSDKLoginButton *)loginButton
didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result
                error:(NSError *)error{
    UINavigationController *nav = [self.storyboard instantiateViewControllerWithIdentifier:@"nav"];
    ViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"LoggedInVC"];
    [nav pushViewController:vc animated:YES];
    [self presentViewController:nav animated:YES completion:nil];
}

“nav”是我的导航控制器的Storyboard ID “vc”是我的第一个连接到导航控制器的视图控制器的故事板ID

Answer 9

AppDelegate到ViewController：

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let loginPageView = mainStoryboard.instantiateViewControllerWithIdentifier("leadBidderPagerID") as! LeadBidderPage
var rootViewController = self.window!.rootViewController as! UINavigationController
rootViewController.pushViewController(loginPageView, animated: true)

在ViewControllers之间：

let loginPageView = self.storyboard?.instantiateViewControllerWithIdentifier("scoutPageID") as! ScoutPage
self.navigationController?.pushViewController(loginPageView, animated: true)

Answer 10

如果您使用的是Swift：

let controller = self.storyboard!.instantiateViewControllerWithIdentifier("controllerID")
self.navigationController!.pushViewController(controller, animated: true)

Answer 11

UIViewController *vc=[self.storyboard instantiateViewControllerWithIdentifier:@"storyboardId"];
[self.navigationController pushViewController:vc animated:YES];

Answer 12

快速4和5

let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "yourController") as! AlgoYoViewController
        navigationController?.pushViewController(vc,
                                                 animated: true)

Answer 13

我们说如果您要从ViewController A-> B 转到

确保您的ViewControllerA 嵌入在导航控制器中
在ViewControllerA的“按钮”中单击，您应该具有以下代码。

@IBAction函数goToViewController（_ sender：Any）{

    if let viewControllerB = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ViewControllerB") as? ViewControllerB {

        if let navigator = navigationController {
            navigator.pushViewController(viewControllerB, animated: true)
        }
    }
}

请仔细检查您的情节提要名称，并检查情节提要中提到的ViewControllerB的标识符

查看 StoryboardID = ViewControllerB

首先创建导航控制器，并将其作为窗口对象的rootViewController提供。

导航控制器推视图控制器
