指定根视图:

    // 设置window的根视图控制器self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[RootViewController new]];

定义属性

#import "RootViewController.h"
#import "FirstViewController.h"
#import "SecondTableViewController.h"
@interface RootViewController ()<UIScrollViewDelegate>
@property (nonatomic, strong) UISegmentedControl *segmentedControl;
@property (nonatomic, strong) UIScrollView *scrollView;
@property (nonatomic, strong) FirstViewController *firstVC;
@property (nonatomic, strong) SecondTableViewController *secondTVC;
@end@implementation RootViewController

创建实现:

- (void)viewDidLoad
{[super viewDidLoad];// 适应scrollViewself.automaticallyAdjustsScrollViewInsets = NO;self.segmentedControl = [[UISegmentedControl alloc] initWithItems:@[@"first", @"second"]];self.navigationItem.titleView = self.segmentedControl;[self.segmentedControl addTarget:self action:@selector(segmentedControlAction:) forControlEvents:UIControlEventValueChanged];self.segmentedControl.selectedSegmentIndex = 0;// 创建scrollViewself.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 64, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height - 64)];[self.view addSubview:self.scrollView];// 设置scrollView的内容self.scrollView.contentSize = CGSizeMake([UIScreen mainScreen].bounds.size.width * 2, [UIScreen mainScreen].bounds.size.height - 64);self.scrollView.pagingEnabled = YES;self.scrollView.bounces = NO;// 创建控制器self.firstVC = [FirstViewController new];self.secondTVC = [[SecondTableViewController alloc] initWithStyle:UITableViewStylePlain];// 添加为self的子控制器[self addChildViewController:self.firstVC];[self addChildViewController:self.secondTVC];self.firstVC.view.frame = CGRectMake(0, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));self.secondTVC.view.frame = CGRectMake([UIScreen mainScreen].bounds.size.width, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));[self.scrollView addSubview:self.firstVC.view];[self.scrollView addSubview:self.secondTVC.view];// 设置scrollView的代理self.scrollView.delegate = self;
}

分段控制器点击方法

- (void)segmentedControlAction:(UISegmentedControl *)sender
{[self.scrollView setContentOffset:CGPointMake(sender.selectedSegmentIndex * self.scrollView.frame.size.width, 0) animated:NO];
}- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{NSInteger n = scrollView.contentOffset.x / scrollView.frame.size.width;self.segmentedControl.selectedSegmentIndex = n;
}

first/和second分别为UIViewController和UITableViewController只设颜色即可看效果(这里不做创建)

最终效果:
