在Cocoa Touch中编程切换视图 [英] Programatically Switching Views in Cocoa Touch

问题描述

如何在iPhone应用程序中以编程方式更改屏幕上的视图？

How would one change the view on the screen programatically in an iPhone app?

我已经能够创建导航视图，并以编程方式推送/这个行为，但是如果我想简单地改变当前的视图（不使用UINavigation控制器对象），什么是最简单的方法来实现这个？

I've been able to create navigation view's and programatically push/pop them to produce this behaviour, but if I wanted to simply change the current view (not using a UINavigation controller object), what is the neatest way to achive this?

一个简单的例子，想象一个带有单个按钮的应用程序，当按下时会显示一个新的视图，或者根据一些内部状态变量显示多个视图中的一个。

A simple example, imagine an application with a single button, when pressed will display a new view, or possibly one of multiple views depending on some internal state variable.

我还没有看到任何示例，尝试这样做，我似乎不足够了解UIViewController / UIView对象之间的关系和初始化过程，以achive这个程序。

I have yet to see any examples that attempt to do this, and I dont seem to understand enough about the relationships and initialisation procedure between UIViewController/UIView objects to achive this programatically.

推荐答案

我使用 presentModalViewController：animated：从我的主窗口的 UIViewController 中调出一个设置视图，然后当用户在设置视图中按下done时，我会在设置视图中调用 dismissModalViewControllerAnimated：，返回父视图：

I use presentModalViewController:animated: to bring up a settings view from my main window's UIViewController and then when the user presses "done" in the settings view I call dismissModalViewControllerAnimated: from the settings view (reaching back to the parent view) like this:

[[self parentViewController] dismissModalViewControllerAnimated:YES];
