问题 I have NSSlider in ViewController that must pass integer value to SecondViewController via segue of type Show and update a View every time I move it. So, moving slider I interactively shuffle images in SecondViewController 's window. I spent a week trying to implement such a behaviour of NSSlider but I failed. Maybe I made wrong connections in Interface Builder. I don't know. If you know any other method to make NSSlider work for shuffling images, tell me, please. See updated answer for

How to make a single shared instance of iAd banner throughout many view controllers?

问题 I have tried using a singleton class in my app delegate but I haven't been able to get that to work. I've also checked out the iAdSuite examples (particularly the containerBanner example because it seemed to be the most relative) but I can't figure it out. If there's a better way to accomplish this without using a singleton class and you can point me in the right direction I'd really appreciate it. Some of my singleton class code is below. Thank you! @interface App Delegate @property (assign)

Passing data between segues without using PrepareForSegue

问题 I'm creating an user setup account with 5 steps using storyboard. Each step have a ViewController: 1º)Input for Name, contact etc, 2º) Import photos, 3º)Input, etc 4º)more inputs 5º)Confirmation Page, if the user click "confirm" -> Get all the inputs and upload to Parse. The only solution i get when i search online for this, is to create a func "Prepare for Segue" and pass the information...But for me, this doesnt make any sense: If i had 1000 viewcontrollers, the first viewcontroller

Reference to the segue source view controller

问题 Within my viewDidLoad I would like some custom code based upon the previous controller. How can I access the segue source controller or the previous segue identifier in the destination controller's viewDidLoad to handle this? 回答1: There is no way to get a reference to the segue that created you. You could create a property (sourceVC in my example) in the destination controller, and assign self to this property in the prepareForSegue method (in the source view controller): [(DestinationVCClass

问题 I just upgraded Xcode to 5.0. I'm still fairly new to cocoa so I hope I'm overlooking something basic. Basically I can't get Xcode to see the custom classes that I want to use as parent classes for view controllers. Originally I wanted to create a custom class for a tableview controller but to simplify the problem I tried it with regular viewcontrollers, but that doesnt work either. What I do: Create new project: Single View Application Add a cocoa class to it (File->New->File->Objective-C

Passing data from a ViewController to a TabViewController

问题 I would like to know what the most efficient way is to pass a variable (say: a string) from one regular ViewController to a TabViewController. (NOT iOS => ONLY OSX) I've been searching and trying different stuff and I know there is the "prepareForSegue" function, but I can't seem te get it working for a Tab View. (I'm trying to pass over 50-70 vars to the next view btw) Is there no way to create a separate file in which I can store all my vars and then import it in the new view controller? I

问题 I'm developing a puzzle game application - watch on youtube - for iPhone, and the actual "in-game" part is almost done . It is a separate Class (subclass of UIView) what initializes with a puzzle clue, puzzle pieces, and is ready to send a message for somebody if the puzzle has solved ("completeness" check invoked on every touchesEnded). Now I'm troubled how to design the whole application pattern programatically. The game needs a main menu view , a puzzle selector view , fromwhich I can

How to Build A Dynamic UIPageViewController

由 纵然是瞬间 提交于 2019-12-06 13:41:34
问题 I have followed the basic tutorial here to create a UIPageViewController that swipes through different ViewControllers, all of which I create on Main.Storyboard. I want to make an application that generates dynamic ViewControllers, meaning I will have to instantiate the ViewControllers in the UIPageViewController programatically. However, I am trying to take everything a bit further. I am going to have a dynamic set of ViewControllers to display based on data I have in Firebase. On each swipe
