Ios UIView&；UIViewController应用程序设计
我正在尝试让我的头周围的视图控制器，子视图控制器，视图，容器等。我正在做一个简单的应用程序，将有一组图标下来的左手边，当点击将打开一个不同的屏幕在右手边。基本设计是： 菜单栏将始终位于左侧，内容位于蓝色框中。我说的我应该具有以下结构是否正确： 然后，当按下左侧UIView上的图像时，我应该将新UIView推到右侧？或者这些应该是UIViewController？集装箱是从哪里来的Ios UIView&；UIViewController应用程序设计,ios,ipad,uiview,xamarin.ios,Ios,Ipad,Uiview,Xamarin.ios,我正在尝试让我的头周围的视图控制器，子视图控制器，视图，容器等。我正在做一个简单的应用程序，将有一组图标下来的左手边，当点击将打开一个不同的屏幕在右手边。基本设计是： 菜单栏将始终位于左侧，内容位于蓝色框中。我说的我应该具有以下结构是否正确： 然后，当按下左侧UIView上的图像时，我应该将新UIView推到右侧？或者这些应该是UIViewController？集装箱是从哪里来的 是否可以通过情节串连板执行此操作，或者不可能链接按钮以将新UIView推送到屏幕的不同部分，因此我需要通过代码执
是否可以通过情节串连板执行此操作，或者不可能链接按钮以将新UIView推送到屏幕的不同部分，因此我需要通过代码执行此操作？我建议使用容器视图控制器作为布局的根，然后在左侧菜单中使用子视图控制器，以及当前所选项目/选项卡的另一个视图控制器。 然后，选择后，只需交换右侧的（子）视图控制器（即，从父视图控制器中删除当前视图控制器并添加新的视图控制器）。
虽然一开始听起来可能有点复杂，但当你继续你的项目时，它更健壮，更容易实现更复杂的场景。我建议使用容器视图控制器作为布局的根，然后在左侧菜单中使用子视图控制器，以及当前所选项目/选项卡的另一个视图控制器。 然后，选择后，只需交换右侧的（子）视图控制器（即，从父视图控制器中删除当前视图控制器并添加新的视图控制器）。

初始化选项卡栏时，它会保留一个ViewController数组。因此，您的权利，viewDidLoad只调用一次。要实现这一点，您所要做的就是保留一个包含所有ViewController的数组，并从中切换它们。如果您愿意，我可以在此发布代码，对于最初的问题来说，这似乎有点过头了- (void)updateChildViewController {

UIViewController *previousVisibleViewController = self.currentlyVisibleViewController;
//We keep and array of both view controllers so that we only have to load them into memory once, so their viewDidLoad is only called once.
