Can you Connect both a TabViewController and a PageViewController to a single ViewController?

Question

I'm Building a TabBar iOS application, and on one of the tabbed views I want to place a pagecontrol object in which I want to the user to be able to swipe through 3 pages (in the same tabbed view). How do I do so?

Answer 1

I put the test code, please try it. This code does NOT using storyboard.

TMTabBarViewController.h

#import <UIKit/UIKit.h>

@interface TMTabBarViewController : UITabBarController

@end

TMTabBarViewController.m

#import "TMTabBarViewController.h"    
#import "TMPagingViewController.h"

@interface TMTabBarViewController ()

@end

@implementation TMTabBarViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

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

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    TMPagingViewController *pagingViewController1 = [[TMPagingViewController alloc] initWithNibName:nil     bundle:nil];
    pagingViewController1.title = @"1";

    TMPagingViewController *pagingViewController2 = [[TMPagingViewController alloc] initWithNibName:nil     bundle:nil];
    pagingViewController2.title = @"2";

   [self setViewControllers:@[
                              pagingViewController1,
                              pagingViewController2
                              ]
                   animated:YES];
}
