问题 I'm trying to perform a segue which it doesn't work. What i'm trying to do is send the data which i have in a textfield in my View Controller(Main), after that i want to send it to a ViewController called OperationsController and after that send it to another Views (CreateController & ListController) so i can use that same data and send it to a php file and get data to populate a table view in ListController.

问题 This question already has answers here : Perform Segue on ViewDidLoad (12 answers) Closed last year . I`m trying to perform a segue if its the first time the app is loading.

问题 Depending on what button is pressed I want to append a list of words to variable (pickedList) declared at the start. When I come to prepare for segue it overwrites what has been added and only using empty array that was added at the start. I am able to append items within the prepare for segue bit and these transfer over but this is not what I want. I am very very new to programming and have searched about a lot but can't seem to find what I am looking for. Thanks in advance! Code looks like

问题 I am having an issue with designing a storyboard. I currently have an app in the app store that was designed with XIB files. I have a tableView placed on a UIViewController - not a tableViewController - that loads a unique viewController for each row that is selected. I am trying to convert this concept to a storyboard.

问题 I have created a UIAlertView for an action which gives me 2 options. I want the user to be able to click on a button and have it perform a Segue. Here's the code I have so far: - (IBAction)switchView:(id)sender { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"Please Note" message:@"Hello this is my message" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Option 1", @"Option 2", nil]; [myAlert show]; } - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:

问题 In the main view of my app I have a table view and two prototype cells. I have configured the segues for each cell using the storyboard. In the view controller I override prepareForSegue to pass information on the selected cell to the destination view. The destination view isn't particularly complex and certainly doesn't require any heavy processing to load. THE PROBLEM When I tap on a cell in the main controller for the very first time, the destination view appears after a long delay, from 5

问题 I have created a custom segue that presents a view controller inside a container that is very similar with Apple's own modal view controllers (I've implemented it as a UIViewController subclass). I'm now trying to create a custom unwind segue but there's no way I can get the method -segueForUnwindingToViewController: fromViewController: identifier: to be called. I've also implemented -viewControllerForUnwindSegueAction: fromViewController: withSender: on my container so I can point to the

问题 I am new to iOS App Development. I have connected a tableview controller such that when I select one of the rows I get another UIViewController using didSelectRowAtIndexPath. I have a container view inside this UIViewController which displays (say for the time being) index of the row on which didSelectRowAtIndexPath was called.

问题 I have two classes, ChargeCustomer and TwelvethViewController . In TwelvethViewController I have a func goNextView() which should perform a segue to next view controller when called. goNextView() is called from class ChargeCustomer inside a Alamofire completion handler. The problem is that this function goNextView() is never called and I can't figure out why.
