标题与View的联动（通过ScrollView实现）

首先我们要创建几个View用来滚动下面是我示例的

接下来就是ScrollView的实现了

<UIScrollViewDelegate,UIPopoverPresentationControllerDelegate>{

NSMutableArray *arr;

UIButton *btn;

}

下面如上图所示

@property (nonatomic, strong) UISegmentedControl *segmentedControl;

@property (nonatomic, strong) UIScrollView *scrollView;

@property (nonatomic, strong) OneViewController *oneVC;

@property (nonatomic, strong) TwoViewController *twoVC;

@property (nonatomic, strong) ThreeViewController *threeVC;

@property (nonatomic, strong) FourViewController *fourVC;

@property (nonatomic, strong) FiveViewController *fiveVC;

@property (nonatomic, strong) SixViewController *sixVC;

然后是一些具体的实现代码部分（viewDidLoad）

//    创建一个view,放分段控制器

UIView *vv = [[UIView alloc]initWithFrame:CGRectMake(0, 64, self.view.frame.size.width, 30)];

//    vv.backgroundColor = [UIColor redColor];

[self.view addSubview:vv];

//    存储分段控制器标题

arr = [NSMutableArray arrayWithObjects:@"移动通讯",@"传媒",@"软工",@"网工",@"云计算",@"建筑",nil];

// 适应scrollView

self.automaticallyAdjustsScrollViewInsets = NO;

//    创建分段控制器

self.segmentedControl = [[UISegmentedControl alloc]initWithItems:arr];

self.segmentedControl.frame = CGRectMake(0, 0, 386, 30);

//    加载到vv上

[vv addSubview:self.segmentedControl];

//    self.navigationItem.titleView = self.segmentedControl;

[self.segmentedControl addTarget:self action:@selector(segmentedControlAction:) forControlEvents:UIControlEventValueChanged];

//    默认第一个视图

self.segmentedControl.selectedSegmentIndex = 0;

// 创建scrollView

self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 94, [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 * 6, [UIScreen mainScreen].bounds.size.height - 64);

self.scrollView.pagingEnabled = YES;

self.scrollView.bounces = YES;

// 创建控制器

self.oneVC = [OneViewController new];

self.twoVC = [TwoViewController new];

self.threeVC = [ThreeViewController new];

self.fourVC = [FourViewController new];

self.fiveVC = [FiveViewController new];

self.sixVC = [SixViewController new];

// 添加为self的子控制器

[self addChildViewController:self.oneVC];

[self addChildViewController:self.twoVC];

[self addChildViewController:self.threeVC];

[self addChildViewController:self.fourVC];

[self addChildViewController:self.fiveVC];

[self addChildViewController:self.sixVC];

//    每个视图

self.oneVC.view.frame = CGRectMake(0, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));

self.twoVC.view.frame = CGRectMake([UIScreen mainScreen].bounds.size.width, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));

self.threeVC.view.frame = CGRectMake([UIScreen mainScreen].bounds.size.width*2, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));

self.fourVC.view.frame = CGRectMake([UIScreen mainScreen].bounds.size.width*3, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));

self.fiveVC.view.frame = CGRectMake([UIScreen mainScreen].bounds.size.width*4, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));

self.sixVC.view.frame = CGRectMake([UIScreen mainScreen].bounds.size.width*5, 0, self.scrollView.frame.size.width, CGRectGetHeight(self.scrollView.frame));

//加载到滚动视图上

[self.scrollView addSubview:self.oneVC.view];

[self.scrollView addSubview:self.twoVC.view];

[self.scrollView addSubview:self.fourVC.view];

[self.scrollView addSubview:self.fiveVC.view];

[self.scrollView addSubview:self.threeVC.view];

[self.scrollView addSubview:self.sixVC.view];

// 设置scrollView的代理

self.scrollView.delegate = self;

//    按钮

btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

//按钮位置

btn.frame = CGRectMake(385, 0, 30, 30);

//    按钮背景颜色

btn.backgroundColor = [UIColor whiteColor];

[btn setTitle:@"+" forState:0];

btn.layer.borderWidth = 1;

btn.layer.borderColor = [UIColor blueColor].CGColor;

//    按钮点击事件

[btn addTarget:self action:@selector(btnclick) forControlEvents:UIControlEventTouchUpInside];

//    加载

[vv addSubview:btn];

代理方法

//分段控制器方法

- (void)segmentedControlAction:(UISegmentedControl *)sender

{

[self.scrollView setContentOffset:CGPointMake(sender.selectedSegmentIndex * self.scrollView.frame.size.width, 0) animated:YES];

}

//滚动视图代理方法

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView

{

NSInteger n = scrollView.contentOffset.x / scrollView.frame.size.width;

self.segmentedControl.selectedSegmentIndex = n;

}
