指定根视图:
[objc] view plain copy
// 设置window的根视图控制器
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[RootViewController new]];
定义属性
[objc] view plain copy
#import "RootViewController.h"
#import "FirstViewController.h"
#import "SecondTableViewController.h"
@interface RootViewController ()
@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:
[objc] view plain copy
- (void)viewDidLoad
{
[super viewDidLoad];
// 适应scrollView
self.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scrollView
self.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
[objc] view plain copy
- (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:
