How to create an IPA on XCode 4.3.2

由 隐身守侯 提交于 2019-12-03 15:09:46
Creating IPAs is no problem on 4.3.1 even though Apple changed the UI flow. Just "Save for Enterprise or Ad-Hoc Desployment" XCode 4.3.2 does not have that option, only "Save Build Products" and "Export as XCode Archive" Has anyone found out how to create an IPA? just set your bundle identifier, click Product –> Archive follow the snaps select Distribute This was not related to XCode 4.3.2 and resolved by making sure that the current scheme did only archive one target. Before Xcode 4.3, when we wanna got a ipa file for our project, we do like this: 1. Product –> Archive 2. Organizer –>

I am getting a random bug in my app, which is causing it to crash. The problem I am facing is XCode doesn't tell me where the crash is happening only the below information. Can someone tell me how I can find out where I might be able to find the problem within the code? It must be crashing at the same point as when the app does crash it always shows the below. * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: 0)' * First throw call stack: (0x381e48bf 0x37d301e5 0x381e47b9 0x381e47db

Good iPad SplitViewController tutorial? [closed]

由 余生长醉 提交于 2019-12-03 05:11:06
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I'm new to iOS development and am trying to learn how to use the iPad's splitViewController. I've seen a couple of tutorials online but they all start with the master-detail template. Can someone suggest a tutorial or give me an example that makes a split-view application from scratch as I want to know how it

问题 I really can't figure out why I have this bug. First of all the debugger stop at machine code The thread also shows nothing. The program stop at no code actually So it has something to do with _dispatch_worker_thread What is that? Any way how I can debug this? Should I just rollback? 回答1: This kind of crash will happen when you are running a (vector)extension which is not supported on your CPU. For example, in xcode 5 under "project-settings / build-settings / Code Generation, set the "Enable

Detect Focus Change for UITextField

问题 I'm trying to set the animation for the view to move up when keyboard is hiding and appearing for the text fields and I got it to work perfectly fine, but when the focus moves from one text field to another, it doesn't work since the keyboard was already shown. In viewDidLoad, I registered the following: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver

value assigned to a property in the model class disappears in the view/controller class

由 99封情书 提交于 2019-12-02 20:06:40
问题 Right before my model class sends the variable stringToDisplay , NSLog shows me that it has a value. But when I try to use it in my ViewController, I just get (null) . Any thoughts about what I'm doing wrong? (The good news is that, while working on this, I had sort of a breakthrough in understanding how models and controllers relate to each other. I'm still a complete newbie, but I don't feel quite as lost as I did.) Here's what I think is the relevant code: CalculatorBrain.h #import
