storyboard

问题 I have been trying to figure this out all day and I know it should be able to be done, but being new to iOS development using Objective-C and not Appcelerator I'm having newbie issues. What I am trying to accomplish is to have an embedded view in one of my other views, but to be able to switch which view is embedded through programming. I am using storyboards. When I tried to use the view container it displays the attached view, but I cannot attach multiple views to the container in the

问题 I have a complex iPad view that I manage by having several view controllers. I previously (before iOS6/XCode 4.5) did this by allocating my view controllers in code, and hooked up the various views to them though links to the master view. What I would like to do is use the new container views to embed the view controllers in the storyboard file. I don't seem to be able to make an IBOutlet link to the embedded view controller to the master controller. Is it possible to do this? Or to retrieve

问题 is there any way to resize a View Controller that has been presented modally using a storyboard segue? how do I present another View Controller from this modal view controller with a flip transition?

In interface builder select the view controller and in the attribute inspector set Size to freeform (from inferred). Then select the view and set its

问题 I've recently upgraded to Xcode 8 and updated my project to Swift 3. All worked fine for a little while. Storyboard loading has always been slow (even when still running Xcode 7) and was about the same 'slow' with Xcode 8. I always imagined this is because I'm on a older (late 2011) Macbook Pro. But recently sometimes Xcode would just hang when I tried to open the storyboard. And since yesterday it's ALWAYS 'hanging'. Xcode becomes unresponsive and I have to Force Quit it. In Activity Monitor

Now in tableView:didSelectRowAtIndexPath method: UITableViewCell *theCellClicked = [self.tableView

问题 I am playing around with the new iOS 5 features and trying to rewriting one of my apps as pure iOS 5 app using the new storyboarding feature. To cut a long story short, I have a start screen where the app tries to connect to a server if the user saved some login data, if not, it should ask for them. Here is how I would do it. I create a Viewcontroller which is doing the connection thing in the viewDidLoad method. If there is no login data or the login is not successful, I need a to do a
