ios4 - Load new view on clicking a button
提问by Angelo
I am currently using XCode 3.2.3 and iOS4. I'm working on an app that simply starts with one screen and on a button click moves to the next.
我目前正在使用 XCode 3.2.3 和 iOS4。我正在开发一个应用程序，它只是从一个屏幕开始，然后单击按钮移动到下一个屏幕。
I have gone thorugh the ViewController programming guide and a post here.
我已经阅读了 ViewController 编程指南和此处的帖子。
What I am doing is very similar to whats happening on the post. So let me explain the steps, I followed:
我正在做的事情与帖子上发生的事情非常相似。所以让我解释一下步骤，我遵循了：
In IB, drag and drop, a View from the library into the editor. I renamed the new UIView to myView.
In my AppControllerDelegate, I added the new view "myView" as a property of the view controller (File's Owner). I synthesized it as well in the implementation.
Now, in the implementation of the ViewController, within the button pressed action handler, I wrote the following lines of code:
在 IB 中，从库中拖放一个 View 到编辑器中。我将新的 UIView 重命名为 myView。
在我的 AppControllerDelegate 中，我添加了新视图“myView”作为视图控制器（文件的所有者）的属性。我在实现中也综合了它。
现在，在 ViewController 的实现中，在按钮按下动作处理程序中，我编写了以下代码行：
[self.view addSubView: myView];
[self.view addSubView: myView];
- On clicking the button however, I do not see a new screen or my new view. However if I do this, I get a new screen or new view:
- 但是，在单击按钮时，我没有看到新屏幕或新视图。但是，如果我这样做，我会得到一个新屏幕或新视图：
UIView *anotherView = [[UIView alloc] initWithFrame:self.view.frame];
[self.view addSubView: anotherView];
UIView *anotherView = [[UIView alloc] initWithFrame:self.view.frame];
[self.view addSubView: anotherView];
I do know that the best way is to do it with separate NIBs for each UIView. However, I am new to iPhone development and have not explored that path as yet.
我知道最好的方法是为每个 UIView 使用单独的 NIB。但是，我是 iPhone 开发的新手，还没有探索过这条路。
My question: What am I missing upto step 3?
我的问题：我在第 3 步之前遗漏了什么？

One way you could be able to do it is by trying it this way
你可以做到的一种方法是通过这种方式尝试
myView = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle: [NSBundle mainBundle]];
[self.view addSubview: myView.view];
Try that and see if it is working.. if yours is a view based project then instead of [self.view addSubview: myView.view], just give [self.view addSubview : myView];
试试看它是否有效..如果你的项目是基于视图的项目，而不是 [self.view addSubview: myView.view]，只需给出 [self.view addSubview : myView];
