问题 As you can see in the screenshot, there's no space between the top image and the top of the screen. Also, all my images are not the same size.

问题 Today is a good day since I started with WPF, this for a launcher I'm creating.

问题 I followed a tutorial about how to create an iOS app where a title image and a background image are shown once a button is hit (there are checked as "hidden" in the attribute inspector). I am using Swift 3 and Xcode 8. That's what the code looks like: import UIKit class ViewController: UIViewController { @IBOutlet weak var background: UIImageView! @IBOutlet weak var titleImage: UIImageView! @IBOutlet weak var welcomeBtn: UIButton! @IBAction func welcomePressed(_ sender: UIButton) { background

问题 Is it possible to customize the prompt string at all? I have hooked up the navigationBarItem to my ViewController and added a string as the "Prompt" via IB. There are no properties following the prompt class that allow me to alter the contents of the string, color, etc etc. I was wondering if anyone knows any other possible work around for this problem? 回答1: It is possible to customize the prompt appearance with one big limitation, the style of the prompt and of the title will always be the

问题 In my application I have a uiview at the top of the screen. When I tap that UIView I have a second View Controller slides up. What I would like to accomplish is that when the second View Controller slides into the screen it stops right before it covers up the UIView What I am trying to accomplish is have a view slide up that contains store information such as hours open, address, phone number etc. So I was thinking that I could just have another view controller that holds all of this

问题 For some reason, only one image of my UITabBarItem does not show up. This started to happen after I refactored the storyboards to organize them. When I run the app, no message is triggered to the debugger, it just don't show up. The image is being set in storyboard and nothing programmatically is being done to set it . It shows up in Interface Builder, but when I run the app it doesn't. Already tried delete the image in catalog, rename it and perform clean up, but nothing helped. 回答1: Few

问题 I have perhaps a beginner's question but have not found any solutions addressing this specific problem after searching endlessly on stackoverflow and other forums. My detail view in the storyboard appears to be too zoomed in. At this point, zooming in and out simply zooms in and out on the storyboard, but not the detail view specifically.

问题 I have this structure in story board (lines represents segues): B / A \ C I want to use A (view controller) as a "hub". But I want to say in C that I want to B . I'll set next target (doesn't matter how) and perform unwind from C to A which know where to go next, and in unwind target action it calls ther right performSegueWithIdentifier but nothing happens. This was supposed to be an proof of concept and it would results in two animations. The target solution would be for user to transition
