Question

我有一个视图控制器，它是我的HomeViewController，我之间有一个模态segue。

这是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

我想向StackTableViewController添加一个导航控制器......它只是一个表视图，我希望它有一个导航控制器，我应该怎么做？

另外，为什么xcode告诉我我的模态方法presentModalViewController已被弃用？

创建UINavigationController的新实例，将StackTableViewController作为其rootViewController。然后出现导航控制器：

- (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，presentModalViewController:animated:已弃用，因为它已被presentViewController:animated:completion:替换。

如何以编程方式在视图中嵌入导航控制器？
