I'd better grab Xcode 5 DP3 before the PowerMac G3 running the dev center falls over again.

Speaking of which, I can't figure this out since the Dev forums are down: how the gently caress can I download the iOS 7 documentation? Xcode 5 keeps spitting back that I'm not a registered developer, despite the fact that I am. I assume this has to do with the dev center issues, but given the dev forums are down, and the docs are down, I don't know how the hell I'm meant to get at the documentation to code for iOS 7 here...

Are you a registered developer with the $100 iOS dev center membership? I don't think the beta downloads are available to free accounts.

Yes. Hence how I have Xcode 5 dp3 installed.

The issue is that, when I attempt to download the docs in Xcode via the Downloads section in prefs, it kicks back that I'm not registered. I am. Similarly, in the accounts tab it's just eternally "fetching developer info" on my dev account.

I assume this has to do with the Dev Center issues, but there has to be some sort of workaround here? This is normally something I'd go to the dev forums for but...yeah.

EDIT: I've also tried deleting/re-adding the account several times, a restart, etc. Nada.

EDIT 2: I suspect this has to do with the "XCode Automatic Configuration" still being down according to the status update.

I have a UITableView as a subview of one of my UIViewControllers (implenting all the datasource and delegate methods). Is there a selector or some sort of notication that is sent out when the UITableView is completely rendered on screen? Basically, I need to wait until all of the rows are displayed before I run something, but I can't seem to find it. The UITableView is created and rendered after the parent's UIViewController's viewWillAppear etc.

A Core Data question/issue/whatever:

I'm trying to abstract away all my app's Core Data stuff (first time I've used Core Data) into a singleton. Various parts of my app need to create model objects (subclasses of NSManagedObject), use them, and hand them to the singleton for safe keeping, and I've run into a design issue.

It seems I can either
1)make the singleton's managed object context publicly visible so that any part of my app can create model objects as-needed, or
2)have the singleton be a factory for every model object

#1 seems icky in terms of implementation hiding and just generally keeping the rest of my app's code free of Core Data, while #2 seems a lot like Java FactoryFactoryFactory stuff (but means I can keep the managed object context private).

Is there another way? Or am I resigned to having a bunch of -newThingWithName:andOtherStuff: methods in the singleton?

Here's what I do:

- Have a singleton NSManagedObjectContext lazily created in a class method, maybe call it +defaultManagedObjectContext.
- In a category on NSManagedObject, add class methods like +insertNew that are implemented using the default managed object context from the above.
- Use a custom class for each entity (set it in your data model) so they can be set up as needed. Optionally, specify your dynamic properties here and add specific conveniences like +[Department insertNewEmployeeWithName:]

The benefit of having a "default context" is you can still create other contexts, make new instances in that context as you'd normally do, then merge them in to the default as needed. Code that needs to do this will have Core Data-specific knowledge, while code that doesn't can remain totally ignorant.

Basically, take a look at what mogenerator outputs, then bolt on the default managed object context.

# ? Jul 30, 2013 07:13

Doc Block: Apr 15, 2003; Fun Shoe

Forgot to mention that I'm already using mogenerator to generate the model object classes. On further inspection, it looks like mogenerator can make the low-level model classes inherit from a custom NSManagedObject subclass instead of directly from NSManagedObject, so I could put the managed object context singleton stuff there instead of having to write it for every class.

I didn't know you could merge managed object contexts together, though I guess it makes sense that you'd need to do that sometimes.

It's nice that Core Data is as powerful and flexible as it is, but I wish it had a simple(r) use path for apps that just need an easy way to persist a few objects (at most a hundred in my app's case) while still having their relationships and such managed for you. Of course, I probably should've learned Core Data a lot sooner...

Anyway, thanks for the advice. Looks like I should probably just stop and read up on Core Data some more.

It'll work, though I wonder if simply using NSCoding and implementing a little relationship management yourself would be easier. Replicating a bit of NSManagedObject's KVO/KVC magic might be fun too.

Implementing NSCoding and just saving/loading your entire object graph is very easy, especially if you only have a couple objects and you don't need to do fancy fetches & such.

Navigating to one of my .m files in Xcode DP4 causes it to hang and fill my hard drive. I've tried deleting / re-adding the file, cleaning the build, deleting Xcode's preferences, and it still does it. Anyone know where I can look to see what the issue is?

edit: 'fixed' it. I trashed the file with its header, then made new files with File>>New FIle, quit Xcode, and copied the contents over in TextEdit.

Yeah, my app already uses NSCoding-compliant model objects and just serializes them out to disk with NSKeyedArchiver, but since I'm doing a major refactor in preparation for iOS 7, including redesigning the data layer, and I figured I'd do it the "right" way this time and use Core Data.

The app does a few fetches, but nothing complicated, and having 100 model objects would be an upper-limit extreme case.

I might just go back to NSCoding, though I don't want to be caught flatfooted if/when I really do need to use Core Data for an app.

Library/Caches can be purged by iOS at any time. If that's unacceptable, put it in Library/Application Support and apply the attribute that prevents backup.

I want to hide a UIViewController's backButton when it's in Landscape but not Portrait. self.navigationItem.hidesBackButton=YES/NO only seems to work when it's called in UIViewController view life cycle methods. So I figured I'd put that in viewWillLayoutSubviews, but that doesn't actually change the backButton as I imagine the navigationItem has already drawn all of its contents.

I tried even doing self.navigationItem.backBarButtonItem = nil in the viewWillLayoutSubviews but that still didn't do anything

Anyone have any suggestions? This is for a UISplitViewController, and I am already using the delegate methods to add my "menu" button to the detailViewController just fine. Maybe I could throw something in there?

I may be wrong, but I think you have to make the entire items array for your navigation bar, and replace it wholesale:

Objective-C code:

    UINavigationItem *items = [[UINavigationItem alloc] init];
    UILabel *titlelabel = [[UILabel alloc] init];
	//set up title
    [items setTitleView:uplabel];

    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@" "
                                                                       style:UIBarButtonItemStylePlain

What's the recommended approach for integrating an ObjC library I'm working on in a separate repository with an iOS app repository? Do most people handle it with git submodules and careful configuration of the target (in case there are tests and other junk in the library's repo that you don't want to build for the iOS app)? Or do people do a ghetto copy and paste into the target project periodically?

Have you heard of / tried CocoaPods?

Don't do submodules. That way lies pain, and dirtied trees. If you want to track external repos use Git subtrees, if CocoaPods isn't your cup of tea (it isn't for everyone and occasionally makes configuration weirdly hard, but I did use it to radically improve a code base once. It was magical). And remember that workspaces resolve project dependencies automatically and implicitly, i.e. without modifying the projects.
