segue

问题 I have started a project that was initially completed following Appcoda's tutorial about using view controllers to pass data between scenes (Find it here: http://www.appcoda.com/storyboards-ios-tutorial-pass-data-between-view-controller-with-segue/) Basically it takes table data from the first scene and the segue connects to another controller that displays the recipe image, prep time, and ingredients. However I wanted to take it one step further and add another view controller that will show

问题 Let's say I have my initial vc called VC1, then I have a second one called VC2. VC1 has a segue to VC2, on VC2 there is a button that will dismiss VC2 and then show VC1. Once VC1 loads I want to run a method but I can't do that in view did load so where can I do it? [VC1] -> [VC2] 回答1: You can use a delegate method to achieve this.

问题 I have a table view controller with a tableview that I set up in the storyboard with a push segue to it from the mapViewController. When the user touched the ios provided annotation callout the function calloutAccessoryControllTapped is called, and it indirectly by way of a notification called [self performSegueWithIdentifier:@"SequeToConversationList" sender:self]; This works fine. However, I replaced the ios supplied callout with a custom callout layed out in a XIB. It has a button with an

问题 Hopefully this is a simple issue? But I just cant seem to get my head around it. I have a text field in my settingsViewController called emailText where I want to set the default email recipient. @IBOutlet weak var emailText: UITextField! override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { let shoppingListViewController = segue.destinationViewController as! ShoppingListViewController shoppingListViewController.emailString = ([emailText.text]!) } func

问题 Suppose that I have a UIButton control and I attached both the @IBAction method on the click and segue to it. Is it guaranteed that the click method will bed called before the segue? Thanks in advance. 回答1: Do this, this will work perfect in your case.. In your first ViewController.h create a property to store indexPath @property (nonatomic,strong) NSIndexPath *indexPath; In your second ViewController.h create a property to store indexPath @property (nonatomic,strong) NSIndexPath *indexPath;

问题 I've been trying to pass variables between view controllers without much luck. I started to work backwards from the problem I was encountering but am now having problems just getting the segue to action.
