如何在视图控制器中以编程方式切换视图？(Xcode,iPhone)

Question

一直苦苦挣扎这一段时间,似乎永远无法得到直接的答案.

任何帮助表示赞赏!

Answer 1

如果您在导航控制器中:

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

或者如果您只是想呈现一个新视图:

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

Answer 2

如果要在同一个故事板中显示新视图,

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,请打开MainStoryBoard.storyboard.选择YourViewController视图 - >实用程序 - > ShowIdentityInspector.在那里你可以指定标识符.

Answer 3

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,如果您只想呈现一个新视图:

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

Answer 4

该instantiateViewControllerWithIdentifier是Storyboard ID.

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

您可以使用

    [self dismissViewControllerAnimated:YES completion: nil];
