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;
}
