segue

问题 I have a Tab bar controller with 2 items. The first item is a VC which contains a table view. Clicking on a cell, performs a segue to some other view controller (not an item on the tab bar controller). The problem is that it removes the tab bar when segue completes. How can I just replace the item 1 with other VC and still keep the tab bar in the bottom? 回答1: You need to embed your Item1VC to NavigationController so that when you push from ItemVC to MoviesViewController it will not remove the

问题 When I click a certain list item in my UITableView, I want to pass the index of the item that I clicked on to the next detailed view.

问题 I have a parent UIViewController and it has two different view containers - each of them has embedded UIViewController inside. It looks somehow like this: I want to change the label on the right container when user presses the button stored on the left one. So far I was able to do it while having a button placed in a parent view controller, then I was just using a protocol: in my parent component I had: class ParentController: UIViewController { var delegateEmbedded:HandleEmbedded? override

问题 I have been trying for some time to create a custom segue that does the opposite of the cover vertical (to create a from top to bottom effect animation).I had looked through other questions, google and youtube but cannot get it working.I am completely new to the classes etc. so any help in a step by step guide or video would be so good.

问题 I have to created a segue programmatically however when I click on the button the view controller does not change to the next, Storyboard ID is set and still not working. Am I missing any other checks in order to make this work? Please see code below: EntryViewController *entryController = [self.storyboard instantiateViewControllerWithIdentifier:@"go"]; [self.navigationController pushViewController:entryController animated:YES]; its driving me mad. Thanks 回答1: Inside my viewDidLoad I have

问题 I'm trying to push data from one viewController to another. I've connected a viewController to another ViewController's navigationController and then set the identifier to "showItemSegue" . I get an error in these two lines: var detailController = segue.destinationViewController as ShowItemViewController detailController.currentId = nextId! Image illustration: The code: override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { nextId =

问题 I would like to segue a destination scene through a button present in source scene. I also would like to have a control of the transition animation between the viewcontroller (I want to animate the 2 views from right to left). Is it possible to do so through the replace segue? I try both the replace segue and the push segue but the segue is not happening any suggestion how i should proceed there? Thanks! 回答1: I found out that the replace segue and push segue were misleading because the

问题 I am trying to make a mechanism to drill down a file / folder list. The idea is to show the same file list view controller every time the user selects a folder, and show a file detail view controller if he/she selects a file. So far, I have created a segue from the file list view controller to the file detail view controller, and a segue from the file list table view cell to the the file list table view controller: The issue with this is that as soon as the user taps the cell, the segue is
