I've been trying to move the back button down a few pixels with no success. extension UINavigationController { func addBackButton() { let imgBack = UIImage(named: "ic_back") navigationBar.backIndicatorImage = imgBack navigationBar.backIndicatorTransitionMaskImage = imgBack navigationBar.topItem?.backBarButtonItem =

问题 I'm relatively new to iOS programming but I'm learning bit by bit. I've got two nib files, one is my HomeViewController and the other is called 'ReceiptTableViewController'. The HomeVC should not have a top nav bar but the ReceiptTableVC should, with a title and 'back' where the user can swipe to go back to HomeVC. How would I go about adding this? I've dragged the Navigation Controller to the side of my ReceiptTableVC in the nib file. I've searched for various answers but some contradict

问题 I've currently got a UITabBar with 5 screens calling UIViews. That part works fine but I want to put in a UINavigationController in a couple of them. I have found a few tutorials that work fine but all of them implement it in IB and I want to avoid that if possible. I'm lost as to where to implement the UINavigationController, should I do it in the App Delegate with the UITabBar and call the navigation controller from the UIView or should I create it in the UIView class? I've tried about 8

问题 I'm normally just use storyboard for my iOS, but needed to integrate an SDK which does not use storyboard, rather xib. My initial view controller is from storyboard, and when a button is pushed (IBAction), I would like it to go to the xib view controller, but not sure how programmatically to do so.
