最近有個(gè)需求是關(guān)于兩個(gè)頁面切換的 剛開始想的是一個(gè)控制器控制兩個(gè)tableView然后進(jìn)行切換 但是這樣的話 一個(gè)控制器的代碼很多肋乍〗胀眩控制起來也很麻煩帆啃。然后就寫了一個(gè)小demo

如圖所示

示例

1.創(chuàng)建 childController鱼喉。創(chuàng)建你所需要滑動跳轉(zhuǎn)的控制器

- (void)setupChildVc{
    
    LeftTableViewController * left = [[LeftTableViewController alloc]init];
    [self addChildViewController:left];
    
    RightTableViewController * right = [[RightTableViewController alloc]init];
    [self addChildViewController:right];

}

2.創(chuàng)建你的按鈕和滑動的scrollView

- (void)setupScrollView{
    self.leftBtn = [[UIButton alloc]initWithFrame:CGRectMake(10, 30, 80, 50)];
    [self.leftBtn setTitle:@"左邊左邊" forState:UIControlStateNormal];
    self.leftBtn.tag = 0;
    [self.leftBtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    [self.leftBtn setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
    [self.view addSubview:self.leftBtn];
    
    self.rightBtn = [[UIButton alloc]initWithFrame:CGRectMake(150, 30, 80, 50)];
    [self.rightBtn setTitle:@"右邊右邊" forState:UIControlStateNormal];
    self.rightBtn.tag = 1;
      [self.rightBtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    [self.rightBtn setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
    [self.view addSubview:self.rightBtn];
    
    
    self.scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 100, 375, 667 - 100)];
    self.scrollView.pagingEnabled = YES;
    self.scrollView.bounces = NO;
    self.scrollView.contentSize = CGSizeMake(375 * 2, 0);
    self.scrollView.delegate = self;
    [self.view addSubview:self.scrollView];
}

3.根據(jù)你滑動和點(diǎn)擊的按鈕去選擇顯示相應(yīng)的View

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
    NSInteger index = scrollView.contentOffset.x / 375;
    [self showVc:index];
}
- (void)showVc:(NSInteger)index {
    CGFloat offsetX = index * 375;
    UIViewController *vc = self.childViewControllers[index];
    
    if (vc.isViewLoaded) {
        return;
    }
    
    [self.scrollView addSubview:vc.view];
    vc.view.frame = CGRectMake(offsetX, 0, 375, 567);
    
}

這樣就能展示出來了。代碼在下邊
