iOS中分段控制器与UIScrollView结合使用

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:
