storyboard

问题 I am attempting to create a very basic login screen, using the Storyboard designer in Xcode 4.2. I'd like a grouped table view to contain the login and password fields. There are some other elements on the view, such as a login button, a forgot password link, etc. Additionally, the background should be able to be tapped to dismiss the keyboard, when a input field has focus. Pre-Xcode 4.2, I accomplished this with a UIView that implemented the UITableViewDataSource protocol, generated and

问题 I have a little bit of a situation here. A few days ago, I accidentally deleted my storyboard, so immediately went into my trash and dragged the storyboard back into the project. Everything worked fine. But then I just emptied my trash and the storyboard no longer appears to be in my project; the storyboard file is showing up red and when I click on it, nothing loads. To my dismay, I thought all was lost so I started building a new storyboard and connecting the classes, outlets and actions. I

问题 I was wondering how to properly use the storyboard to put up a view controller modally. Personally I prefer working with xibs, but it seems that the storyboard is gaining popularity and will be the way to go in the future. The way I would normally put up a view controller modally would be like this: let's say we have ViewControllerA (A for short) and ViewControllerB (B for short). I would then normally put a protocol in B.h specifying the delegate method when B wants to be dismissed and add

问题 I want to switch between multiple view controllers with a UIPageViewController . These view controllers are static though so i want to design them in my storyboard. Since one can't use relationships or segues to connect them to the UIPageViewController but a datasource, I need to have a datasource object with an IBOutletCollection holding the pages: @property (retain, nonatomic) IBOutletCollection(UIViewController) NSArray* pages; Although, I am not able to connect this outlet to the view
