如何以编程方式在视图中嵌入导航控制器? [英] how to embed navigation controller in a view programmatically?

问题描述

我有一个View Controller，它是我的HomeViewController，并且它们之间有模式选择.

I have a view controller which is my HomeViewController, and I have a modal segue between them.

这是HomeViewController:

This is the HomeViewController:

import "HomePageViewController.h"
#import "CreatePageViewController.h"
#import "StackTableViewController.h"
#import "PopUpView.h"


@interface HomePageViewController ()

@property (nonatomic, strong) IBOutlet UIButton *toggleButton;
@property (nonatomic, strong) CreatePageViewController *modalTest;
@property (nonatomic, strong) PopUpView *popup;

@end

@implementation HomePageViewController

-(UIStatusBarStyle)preferredStatusBarStyle{
    return UIStatusBarStyleLightContent;
}

-(void)viewDidLoad {
    [super viewDidLoad];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:Nil];
    _modalTest = [storyboard instantiateViewControllerWithIdentifier:@"ModalTest"];

    [_toggleButton addTarget:self action:@selector(go) forControlEvents:UIControlEventTouchUpInside];

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(hide) name:@"HideAFPopup" object:nil];
}

-(void)go {

    _popup = [PopUpView popupWithView:_modalTest.view];
    [_popup show];
}

-(void)hide {

    [_popup hide];
}
- (IBAction)pushToNextViewController:(id)sender {

    StackTableViewController *vc = [[StackTableViewController alloc]init];
    [self presentModalViewController:vc animated:YES];
}


-(void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

@end

我想在StackTableViewController中添加一个导航控制器...它只是一个表视图，并且希望它具有一个导航控制器，我该怎么做?

I want to add a navigation controller to StackTableViewController...its just a table view and I want it to have a navigation controller, how should I do this?

此外，为什么xcode告诉我我的模态方法presentModalViewController已弃用?

Also, why xcode tells me my modal method presentModalViewController is deprecated?

tnx

推荐答案

使用您的 StackTableViewController 作为其 rootViewController 创建 UINavigationController 的新实例.>.然后显示导航控制器:

Create a new instance of UINavigationController, with your StackTableViewController as its rootViewController. Then present the navigation controller:

- (IBAction)pushToNextViewController:(id)sender {

    StackTableViewController *vc = [[StackTableViewController alloc]init];
    UINavigationController *navCtrl = [[UINavigationController alloc] initWithRootViewController:vc];
    [self presentViewController:navCtrl animated:YES completion:nil];

}

请注意，不赞成使用 presentModalViewController:animated:，因为它已由 presentViewController:animated:completion:代替.

Note that presentModalViewController:animated: is deprecated because it has been replaced by presentViewController:animated:completion:.
