你可以連接一個TabViewController和PageViewController到一個ViewController嗎？

Question

我正在構建一個TabBar iOS應用程序，並且在其中一個選項卡式視圖中，我想放置一個pagecontrol對象，讓用戶能夠在其中滑動3頁（在相同的選項卡式視圖中）。我該怎麼做？

我把測試代碼，請嘗試。 此代碼不使用故事板。

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]; 
}

    [self.view addSubview:_pageControl]; 
}

{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
}

    CGSize viewSize = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height - self. tabBarController.tabBar.frame.size.height); 
    _scrollView.frame = CGRectMake(0.0f, 0.0f, viewSize.width, viewSize.height); 
    _scrollView.contentSize = CGSizeMake(viewSize.width * _pageControl.numberOfPages, viewSize.height);

     if ((NSInteger)fmod(self.scrollView.contentOffset.x , pageWidth) == 0) { 
      // set pageControl indicator to current page. 
      _pageControl.currentPage = self.scrollView.contentOffset.x/pageWidth; 
     } 
    } 
}
