我想弄清楚如何使用一个UISegmentedControl的不同状态来切换视图,类似苹果的付费顶“和“热门免费”之间switiching时是怎么做的在App Store中。

有帮助吗?

解决方案

的最简单的方法是具有可以切换它们的可见性,以指示哪个视图已经被选择两个视图。下面是它如何做,绝对不是一种优化的方式来处理的意见,但一些示例代码只是为了演示如何使用的 UISegmentControl 的切换可见的视图: 点击 结果

- (IBAction)segmentSwitch:(id)sender {
  UISegmentedControl *segmentedControl = (UISegmentedControl *) sender;
  NSInteger selectedSegment = segmentedControl.selectedSegmentIndex;

  if (selectedSegment == 0) {
    //toggle the correct view to be visible
    [firstView setHidden:NO];
    [secondView setHidden:YES];
  }
  else{
    //toggle the correct view to be visible
    [firstView setHidden:YES];
    [secondView setHidden:NO];
  }
}

,点击 可以当然进一步重新因子的代码隐藏/显示右视图。

其他提示

在我的情况,我的观点是非常复杂的,我不能只是改变的不同意见的隐藏属性,因为它会占用太多的内存。

我试过几种解决方案,并将其非为我工作,或无法正常进行,特别是与导航栏并不总是显示segmentedControl入栈/视图时的titleview的。

我发现这个博客文章,解释如何做到这一点的正确方法的问题。似乎他有苹果公司的工程师在WWDC'2010援助想出这个解决方案。

在这个环节的解决方案是手了最好的解决方案,我迄今发现有关问题。随着调整的一点点,也能正常工作用的TabBar在底部

或者,如果它的一个表,则可以重新加载表,并在cellForRowAtIndex,基于段的选项从不同数据源填充该表中选择。

一个想法是具有与分段控件的视图已您与不同子视图填充容器视图(当段被切换添加作为容器视图的鞋底子视图)。你甚至可以对那些子视图单独视图控制器,虽然你有,如果你需要他们(以及他们将被告知他们是什么导航控制器下),像“viewWillAppear中”和“viewWillDisappear”重要的方法来转发。

普遍认为效果很好,因为你可以在IB容器铺陈主视图和子视图将填充任何空间的容器可以让他们有(请确保您的自动调整大小掩码设置正确)。

试试这个代码,这将帮助你上段控制的改变段

的不同视图之间切换

上选择UISegmentControl的不同段<打开不同视图/ A>

请尝试使用 SNFSegmentedViewController ,但这正是一个开源组件,你在找什么用设置像UITabBarController

}

- (IBAction)segmentSwitch:(UISegmentedControl*)sender {
    NSInteger selectedSegment = sender.selectedSegmentIndex;
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.2];
    if (selectedSegment == 0) {

        firstView.frame = leftRect;
        secondView.frame = centerRect;
    }
    [UIView commitAnimations];
}
@end

分配.H在

 UISegmentedControl *lblSegChange;

- (IBAction)segValChange:(UISegmentedControl *) sender

声明.M

- (IBAction)segValChange:(UISegmentedControl *) sender
{

 if(sender.selectedSegmentIndex==0)
 {
  viewcontroller1 *View=[[viewcontroller alloc]init];
  [self.navigationController pushViewController:view animated:YES];
 }
 else 
 {
  viewcontroller2 *View2=[[viewcontroller2 alloc]init];
  [self.navigationController pushViewController:view2 animated:YES];
 }
} 

夫特版本:

在父视图控制器负责设置每个子视图控制器的视图的大小和位置。子视图控制器的视图变为父视图控制器的视图层次结构的一部分。

定义延迟属性:

private lazy var summaryViewController: SummaryViewController = {
   // Load Storyboard
   let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)

   // Instantiate View Controller
   var viewController = storyboard.instantiateViewController(withIdentifier: "SummaryViewController") as! SummaryViewController

   // Add View Controller as Child View Controller
   self.add(asChildViewController: viewController)

   return viewController
}()

private lazy var sessionsViewController: SessionsViewController = {
    // Load Storyboard
    let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)

    // Instantiate View Controller
    var viewController = storyboard.instantiateViewController(withIdentifier: "SessionsViewController") as! SessionsViewController

    // Add View Controller as Child View Controller
    self.add(asChildViewController: viewController)

    return viewController
}()

显示/隐藏子视图控制器:

private func add(asChildViewController viewController: UIViewController) {
    // Add Child View Controller
    addChildViewController(viewController)

    // Add Child View as Subview
    view.addSubview(viewController.view)

    // Configure Child View
    viewController.view.frame = view.bounds
    viewController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

    // Notify Child View Controller
    viewController.didMove(toParentViewController: self)
}

private func remove(asChildViewController viewController: UIViewController) {
    // Notify Child View Controller
    viewController.willMove(toParentViewController: nil)

    // Remove Child View From Superview
    viewController.view.removeFromSuperview()

    // Notify Child View Controller
    viewController.removeFromParentViewController()
}

管理SegmentedControl tapEvent

private func updateView() {
    if segmentedControl.selectedSegmentIndex == 0 {
        remove(asChildViewController: sessionsViewController)
        add(asChildViewController: summaryViewController)
    } else {
        remove(asChildViewController: summaryViewController)
        add(asChildViewController: sessionsViewController)
    }
}

当然,你可以向你的孩子视图控制器类中使用:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    print("Summary View Controller Will Appear")
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    print("Summary View Controller Will Disappear")
}

:一种快速夫特版本:

@IBAction func segmentControlValueChanged(_ sender: UISegmentedControl) {

    if segmentControl.selectedSegmentIndex == 0 {

        // do something
    } else {

        // do something else
    }
}
