iOS 5 从 UIActionSheet 按钮加载视图
有一个 iOS 5 故事板问题。我使用 Storyboard 构建的第一个应用程序，我喜欢使用它们，但我一生都无法弄清楚如何从 UIActionSheet 按钮加载视图。我的 UIActionSheet 运行得很好，它加载了一个 UIAddressBook 选择器，但我想让它切换到一个新的故事板视图控制器。
有什么想法吗？
这是一些代码：
// Specify what to do when a user selects a button from the personSelectQuery
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0) {
[self showAddressPicker];//This works just fine to show the address book
} else if (buttonIndex == 1){
[self showAddPersonView];//This is the custom storyboard view i want to load
}
}
Got an iOS 5 storyboard question. First app I'm building with Storyboards and i like using them, but i can not for the life of me figure out how to load a view from a UIActionSheet button. I have the UIActionSheet running just fine and it loads a UIAddressBook picker, but I want to have it switch to a new storyboard view controller.
Any ideas?
Here's some of the code:

{
if (buttonIndex == 0) {
[self showAddressPicker];//This works just fine to show the address book
} else if (buttonIndex == 1){
[self showAddPersonView];//This is the custom storyboard view i want to load
}
}

[UIStoryboard instantiateViewControllerWithIdentifier:]方法。您可以在IB的属性检查器中为特定ViewController设置标识符。您使用此标识符作为参数调用上述方法，iOS 会从故事板实例化 ViewController。其余的与其他没有 Storyboard 的 ViewController 相同。Look at the
[UIStoryboard instantiateViewControllerWithIdentifier:]method. You can set an identifier for specific ViewController in attribute inspector of IB. You call above method using this identifier as a parameter and iOS instantiates the ViewController from storyboard. The rest is the same as other ViewControllers without Storyboard.
