更改 UISplitView 内的 RootViewController
我正在通过 UISplitView XCode 模板为 iPad 开发一个小示例。它由窗口左侧显示的根控制器和右侧显示的详细视图组成。
我想要实现的目标非常简单（至少我这么认为），但我在文档中找不到实现它的方法。
我想用新控制器替换根控制器（固定在左侧）（例如，作为对按下按钮时启动的事件的响应）。我已经尝试过：
ColorPicker *controlador = [[ColorPicker alloc] initWithNibName:nil bundle:nil];
[self.rootViewController presentModalViewController:controlador animated:YES];
[controlador release];
发生的情况是新推送的控制器填充了整个窗口，而我想要的是固定在左侧，并具有开头的两列格式。
I'm developing a little example for iPad from a UISplitView XCode Template. It's formed by a root controller which is shown in the left of the window and a detail view which is shown in the right.
What I want to achieve is very simple (at least I think so) but I can't find in the documentation the way to do it.
I'd like to substitute the root controller (which appears fixed in the left) with a new controller (for example as response to a event launched when you push a button). I've tried this:
ColorPicker *controlador = [[ColorPicker alloc] initWithNibName:nil bundle:nil];
[self.rootViewController presentModalViewController:controlador animated:YES];
[controlador release];
What happens with that is that the new pushed controller fills the entire window, whereas what I want is that appears fixed at the left with the two columns format that were at the beginning.

您需要将
modalPresentationStyle设置为适当的值，UIModalPresentationCurrentContext指示视图控制器以模态方式显示在rootViewController的框架内。You need to set the
modalPresentationStyleto an appropriate value,UIModalPresentationCurrentContextinstructs the view controller to appear modally within the frame of therootViewController.使用
pushViewController:animated可能会解决这个问题。关于 ModalViewController，请查看文档 http://developer.apple.com /library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.htmlUse
pushViewController:animatedinstead may fix this. About ModalViewController, check document http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.html
