Create custom class for Navigation Controller (Immediate crash)

阅读更多关于 Create custom class for Navigation Controller (Immediate crash)

问题 I'm working on a Storyboards based app which constitutes of multiple view controllers linked via a Navigation Controller (initial view controller). This is used as the home screen. I'm using static cells and a static table view . Now, I want to hook up some labels, buttons, etc as outlets/actions to " the .h " file and subsequently write custom methods in the .m file. But (as expected?) there's yet no custom class to select from in the identity inspector . So I created a new custom class as a

How to get iAdBannerView to stretch across full width of Adaptive Layout Storyboard xcode 6

阅读更多关于 How to get iAdBannerView to stretch across full width of Adaptive Layout Storyboard xcode 6

问题 Just wondering how you are supposed to stretch the iAdBannerView across the full width of the Adaptive Layout Storyboard that exists in Xcode 6. When I try and stretch it to the corners (so I can set auto layout values), it does allow it to be stretched. 回答1: Your ADBannerView will know which device it is on and set its dimensions correctly. You should just let auto layout know where you want the ad to be. For example, if you wanted the ADBannerView to be at the bottom of the screen then pin

Animate to a storyboard state / position

阅读更多关于 Animate to a storyboard state / position

问题 I've got a view controller in Storyboard that has a bunch of images, labels and buttons correctly positioned for how the view is supposed to look after initial animations. Is there a simple way to save the original position of each and every element (that is to say the position that they're in on the Storyboard) on init so that it's possible to take those elements, move them out of view and animate them to the Storyboard layout / positions? 回答1: Yes this can be done by saving all the view's

AutoLayout with size classes: Different spacing depending on iPhone screen size

阅读更多关于 AutoLayout with size classes: Different spacing depending on iPhone screen size

问题 I have a UIViewController set up in an UIStoryboard in Interface Builder using size classes. This looks good on an iPhone 5 with the 4" screen, but on the 5.5" screen of the iPhone 6 Plus the elements are too cramped in the top area of the device. I want to increase the constant of the spacing constraints on iPhone 6 and 6 Plus. As far as I was able to see that's not possible with size classes, as there is only one size class for all iPhone displays (no matter if 3.5" or 5.5"). What is the
