uistoryboardsegue

问题 I am working in Xcode 4.5.2, targeting iOS6 for an iPad app, using storyboards and segues. Preamble: my root controller (loaded by the app delegate) is a splash screen with only an image, an upgrade button and an open button. App takes a few seconds to load.

问题 I've been trying to set a tuple to the sender object when doing a perform segue like: performSegue(withIdentifier: "", sender: ("hello", "hello2")) But inside override func prepare(for segue: UIStoryboardSegue, sender: Any?) I'm getting cast exception when trying to cast sender as (String, String) It seems that only the first element of the tuple is in sender . I'd expect since sender is of type Any? I could use a tuple as variable? Has anyone else experienced this? 回答1: Per the documentation

问题 I have a created a custom segue like below class DismissSegue: UIStoryboardSegue { override func perform() { sourceController.dismissViewControllerAnimated(true, completion: nil) } } In some scenarios I want to dismiss my currentVC without animation but in some cases with animation.

问题 I have 2 questions about this storyboard test project. I am new to Xcode, and I can't find solution to this problem. This is Storyboard setup View Controller A is Root View Controller. View B and View C extend from it separetely. Table View extends from View C. View B has 2 buttons - To Table View and to View B.

问题 The segue runs but the app crashes with the above error. Why do I get this no segue with identifier message? I defined the segue Identifier. Here is the viewDidAppear method - (void)viewDidAppear:(BOOL)animated { [self performSegueWithIdentifier:@"showAlerting" sender:self]; } - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([[segue identifier] isEqualToString:@"showAlerting"]) { NSLog(@"Logging showAlerting"); } } I got these log messages 2015-03-28 20:04:33.025

问题 So I have two navigation controller hierarchies that both lead to one view controller. I pass that one view controller data based on which one presented it with a push segue. How do I dismiss the final view controller and go back to the navigation stack that presented it? I don't need to pass any info back, but when I tried to do an unwind segue I was getting an error stating "this class is not key value coding-compliant for the key doneButtonTapped" I tried unWind segue and popVC segue.

问题 I've got a custom UIStoryboardSegue called leftToRightSegue . Every time this segue is triggered and I move back to the source view, the viewdidload method of the sourceViewController is called.

This is the code I'm using for the segue: #import "LeftToRightPushSegue.h" #import "QuartzCore/QuartzCore.h" @implementation LeftToRightPushSegue -(void)perform { UIViewController *sourceViewController = (UIViewController*)[self

问题 From questions like this and this, I know how to have a UIViewImage push to a new UIViewController programatically. But how can I do this in completely in Storyboard ? I like Storyboard and would like to not have multiple xib files everywhere. I've already enable User Interaction through Storyboard , but I still can't create a transition... 回答1: Drag UIViewController object onto your Storyboard canvas Select that ViewController and in the top menu bar, click Editor > Embed in > Navigation
