The problem is that this is a prototype cell. It is meaningless to have an outlet to something in it, because it isn’t a real cell: it’s a model for what might be dozens or hundreds of cells, and which one would the outlet point to in that case?
A push Segue is adding another VC to the navigation stack. This assumes that VC that originates the push is part of the same navigation controller that the VC that is being added to the stack belongs to. Memory management is not an issue with navigation controllers and a deep stack. As long as you … Read more
There are two options: Option 1 Xcode can “reload” the file by converting the file to either an [Interface Builder Cocoa Touch Storyboard] file type or a [Localizable Strings] file type. Select your base storyboard file from the Project Navigator Find the Localization section in the File Inspector If your file is currently a [Localizable … Read more
Yes, use ‘Show’ instead of ‘Push’ How can I make “show” work like push? Is it possible or should I use “push (depricated)” instead? It should; it does for me. I am using Xcode 6 beta 2 and to test I used the single view template (calling the pre made view controller in IB ‘VC_A’). … Read more
great question – but unfortunately only a lame answer. I don’t believe that it is currently possible to do what you propose because there are no initializers in UIStoryboard that allow overriding the view controller associated with the storyboard as defined in the object details in the storyboard on initialization. It’s at initialization that all … Read more
Objective-C: UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@”MainStoryboard” bundle:nil]; UITabBarController *rootViewController = [storyboard instantiateViewControllerWithIdentifier:@”tabBarcontroller”]; [[UIApplication sharedApplication].keyWindow setRootViewController:rootViewController]; Swift : let mainStoryboard: UIStoryboard = UIStoryboard(name: “Main”, bundle: nil) let viewController = mainStoryboard.instantiateViewControllerWithIdentifier(“tabBarcontroller”) as UITabBarController UIApplication.sharedApplication().keyWindow?.rootViewController = viewController; Swift 3: let mainStoryboard: UIStoryboard = UIStoryboard(name: “Main”, bundle: nil) let viewController = mainStoryboard.instantiateViewController(withIdentifier: “tabBarcontroller”) as! UITabBarController UIApplication.shared.keyWindow?.rootViewController = viewController Swift … Read more
It’s possible in iOS 6 and later: You have to implement the method – (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender In your view controller. You do your validation there, and if it’s OK then return YES; if it’s not then return NO; and the prepareForSegue is not called. Note that this method doesn’t get called automatically when triggering … Read more
My full example is here, but I will provide a summary below. Layout Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably). Make the swift file the xib file’s owner. Code Add the following code to the … Read more
From you image it seems like you presented the ViewController using push The dismissViewControllerAnimated is used to close ViewControllers that presented using modal Swift 2 navigationController.popViewControllerAnimated(true) Swift 4 navigationController?.popViewController(animated: true) dismiss(animated: true, completion: nil)
Putting the widget/view in a separate .xib file works, and is appropriate especially if you might want to reference that same view from multiple View Controllers. However, sometimes you do want to see the additional view/widget within the same storyboard, and it is possible. Here’s how you do it: Select your view controller in IB … Read more
