Okay, my understanding, then, is that the inheritance is just in the model - makes sense. If you subclass NSManagedObjects for the parent and child entities, you need to explicitly declare and synthesize (dynamically) all common properties you want to access at lower levels of the hierarchy

Re: settings to build for 10.5 on 10.6?

I guess I wasn't clear. Deployment target is 10.5. Base SDK is 10.5. Runs fine on 10.6 but crashes in Core Animation on 10.5. The question is what *else* I need to change to make it run on 10.5. To put it another way: if you are developing on 10.6 and your app successfully does Core Animation on 1

Thank you Hank that is just what I needed to see. I must've glossed over the docs you reference below. But something just occurred to me with respect to your point regarding UITableViewCells, userinfo and NSIndexPath. If I associate an NSIndexPath* with a timer and I insert 10 timers - each in

Try running it from outside the debugger. DVDInitialize() uses ptrace() with PT_DENY_ATTACH to stop it from being used in a debugger. -- Steve On 16-Sep-2009, at 18:29 , Quincey Morris wrote: This may not be the correct lis

#pragma to suppress a warning message

I have three related questions. I’d like to suppress a particular warning message in the source file. In gnu it could be done as follows: #pragma Warnings(Off) NSArray *languages = [NSLocale preferredLanguages]; #pragma Warnings(On) Is there a way to do this in xcode with #pra

Re: #pragma to suppress a warning message

If you're just wanting to use the method and avoid the warning, add a category to NSLocale declaring the preferred languages. Just add the interface; no implementation is necessary. You may want to do further investigation; however. It's possible that the preferredLanguages method appeared mid-wa

Re: #pragma to suppress a warning message

Also, can anyone point me to a list of the #pragma’s for xcode? I'm not sure what you are referring to when you say that your pragam warnings would have worked "In gnu". Xcode is an IDE. The compiler most commonly used with Xcode is gcc which is the GNU C compiler. In Snow Leopard, you c

re: How to create subentity object inheriting from superentity object in core data

I've got a generalization in my core data model with entities named A, B, C let's say where A is a super class with subentities B and C. A is not abstract, so if I create an A NSManagedObject, I need to create and relate a single B or C subclass object. How do I make this happen? I can create the
