如何在视图控制器中以编程方式切换视图？ （Xcode，iPhone）

Question

一直在努力解决这个问题，似乎永远无法得到直接答案。

感谢任何帮助！

Answer 1

如果您在导航控制器中：

ViewController *viewController = [[ViewController alloc] init];
[self.navigationController pushViewController:viewController animated:YES];

或者您只想提出一个新观点：

ViewController *viewController = [[ViewController alloc] init];    
[self presentViewController:viewController animated:YES completion:nil];

Answer 2

如果您想在同一个故事板中展示新视图，

在CurrentViewController.m中，

#import "YourViewController.h"

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
YourViewController *viewController = (YourViewController *)[storyboard instantiateViewControllerWithIdentifier:@"YourViewControllerIdentifier"];
[self presentViewController:viewController animated:YES completion:nil];

要将标识符设置为视图控制器， 打开MainStoryBoard.storyboard。 选择YourViewController 视图 - ＆GT;实用程序 - ＆gt; ShowIdentityInspector。 在那里你可以指定标识符。

Answer 3

instantiateViewControllerWithIdentifier是Storyboard ID。

NextViewController *NVC = [self.storyboard instantiateViewControllerWithIdentifier:@"NextViewController"];
[self presentViewController:NVC animated:YES completion:nil];

Answer 4

Swift 版本：

如果您在导航控制器中：

let viewController: ViewController = self.storyboard?.instantiateViewControllerWithIdentifier("VC") as ViewController
self.navigationController?.pushViewController(viewController, animated: true)

或者，如果您只想提供新视图：

let viewController: ViewController = self.storyboard?.instantiateViewControllerWithIdentifier("VC") as ViewController
self.presentViewController(viewController, animated: true, completion: nil)

Answer 5

通过CmdSft

关闭使用之前的答案代码调用的Viewcontroller

    ViewController *viewController = [[ViewController alloc] init];    
    [self presentViewController:viewController animated:YES completion:nil];

你可以使用

    [self dismissViewControllerAnimated:YES completion: nil];

Answer 6

Swift 3.0版本

如果你想提出新的控制器。

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "controllerIdentifier") as! YourController
self.present(viewController, animated: true, completion: nil)

如果你想推送到另一个控制器（如果它在导航中）

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "controllerIdentifier") as! YourController
self.navigationController?.pushViewController(viewController, animated: true)

Answer 7

#import "YourViewController.h"

推送包含导航栏和/或标签栏的视图：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"YourStoryboard" bundle:nil];
YourViewController *viewController = (YourViewcontroller *)[storyboard instantiateViewControllerWithIdentifier:@"YourViewControllerIdentifier"];
[self.navigationController pushViewController:viewController animated:YES];

要将标识符设置为视图控制器，请打开YourStoryboard.storyboard。选择YourViewController视图 - ＆gt;实用程序 - ＆gt; ShowIdentityInspector。在那里你可以指定标识符。

Answer 8

这对我有用：

NSTimer *switchTo = [NSTimer scheduledTimerWithTimeInterval:0.1
           target:selfselector:@selector(switchToTimer)userInfo:nil repeats:NO];

- (void) switchToTimer {
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPad" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:@"MyViewControllerID"]; // Storyboard ID
[self presentViewController:vc animated:FALSE completion:nil];
}

Answer 9

[self.navigationController pushViewController:someViewController animated:YES];

Answer 10

Swift 3.0 in

一个视图控制器到secondviewcontroller go：

let loginVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MsgViewController") as! MsgViewController
        self.navigationController?.pushViewController(loginVC, animated: true)

第二个viewcontroller到1stviewcontroller（后退）：动作事件的后退按钮： -

self.navigationController?.popViewController(animated:true)

3rdviewcontroller到1st viewcontroller跳转

self.navigationController?.popToRootViewController(animated:true)

导航栏中最重要的故事板未点击确保比此后退动作执行

Answer 11

我认为OP正在询问如何在不更改viewCONTROLLER的情况下交换VIEW。我误会他的问题了吗？

他想用伪代码做到：

让myController =实例化（someParentController）

让view1 = Bundle.main.loadNib（....）as ...等等 myController.setThisViewTo（view1）

让view2 = Bundle.main.loadNib（....）as ...等等 myController.setThisViewTo（view2）

我把他的问题弄错了吗？
