storyboard

问题 Suppose I have a storyboard with a navigation controller and several view controllers. All is well until I try to add a new view controller and would like to associate it with the existing UINavigationController . When I go to Editor>Embed>Navigation Controller, Xcode helpfully creates a new controller, which is precisely what I don't want. When I attempt to drag to create a wireframe, I create a segue relationship, which again is what I don't want. Is there a way to make new view controllers

问题 I have a small problem with updating an UILabel. I tried a "Pong" Game tutorial which uses UIViews for the ball and the players. So I positioned them with the help of the storyboard on their start positions. The game works well, but if I implement a UILabel for displaying the players scores the trouble starts. With every update of the UILabel the UIViews get repositioned to their starting points. Was there something changed in iOS 6? 回答1: I ran into a similar issue. The solution was to turn

问题 After migrating image resources to an Asset Catalog the app builds and runs correctly but the assets don't show up in Xcode's storyboard. 回答1: In my case this occurred because I used the full asset name including file extension (i.e. '.png') in Storyboard.

问题 I currently have a button called continueButton that has been assigned to a UIBarButtonItem button in a Storyboard file. I've declared the button as such: - (IBAction)continueButton; When the view loads, I want the button to disable itself, so that there can be no user input unless a command is called that re-enables user input for the button. How would I go about doing this? I'm trying to use the function [continueButton setEnabled:YES]; to disable/enable the button programmatically, but it

问题 I'm using Storyboard to set my constraints. While everything is perfect, I have a some views where I wish to change the constraints on only 3.5" devices. Is this possible? How can I do it? 回答1: You can define a macro to determine the screen size, like the following: #define isiPhone4 ([[UIScreen mainScreen] bounds].size.height == 480)?TRUE:FALSE Later in the code you can do something like this: if (isiPhone4) { self.constraint.constant = NEW_VALUE; } To access storyboard constraints from code
