UINavigationController subclass won't load its nib.
Hi, To put it shortly, my UINavigationController doesn't load its assigned NIB at all. I've got an UINavigationController subclass that contains the code for an object inspector in an app i'm writing. It's declared as the file's owner of a nib of the same name, this nib helps me build the ui of the various subviews pushed as details of some parameter, selected on a root table view. (ie a somewhat classical way for an inspector on ios). Now, I instantiate my view controller with: [ [ MyNavController alloc ] initWithNibName: @MyNavController bundle: nil ]; And display it in a popover. The popover remains empty. loadView is called but it doesnt not contain the root view assigned in IB. None of my outlets are populated, I overloaded some setters, they aren't called at all. All other objects aren't instantiated by the way... ...Therefore I guess the NIB isn't even loaded! To rule out a potential resource loading error, I wrote a nib loading method of mine using UINib. And it works, the NIB is correct, everything is correct. Except that UINavigationController doesn't want to load its assigned NIB.

Dependency between document types
I've switched to using the asynchronous -openDocumentWithContentsOfURL:display:completionHandler:, and now I have a problem. My app requires that one type of document (which provides a library of elements added to the real documents) be open before the untitled document gets created. This worked fine before, when the library doc was opened synchronously, but now it doesn't. I could override -makeUntitledDocumentOfType:error: to check for the library doc first, set a flag if it's not ready, and have the library doc open operation check that flag and create a new document. But is there a better way?

Correct way to change NSPersistentDocument subclass MOC type?
I want to change my NSPersistentDocument subclass to use a different concurrency type. But I can't find a way to override -managedObjectContext that works. The only discussions online I could find are from 5 years ago. It does seem to work if I set the MOC in one of the -initXXX methods, but that seems brittle. -- Rick signature.asc Description: Message signed with OpenPGP using GPGMail ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Correct usage of NSTextView and NSFindBar
Dear Kevin,
I finally managed to find some moments to get back to this issue. So, taking
your advice I changed my approach so that now my data model has a single
textstorage per file/document being managed. When the user selects a file in
the list then I do
[textView.layoutManager replaceTextStorage:fileDocument.textStorage];
This works just as well as the old approach with regards swapping out the
contents of the textview, but still the textfinder is behaving badly.
I still get the false search results and I often get errors like the one below
if I first search one document then switch documents with the find bar open.
Additionally, continuing the search (hitting the enter key) after switching
documents sometimes works and sometimes doesn’t (in the sense that sometimes
new search results are highlighted and sometimes not) - I can’t figure out the
chain of events that leads to this behaviour. It may be that this particular
bad behaviour only happens once I’ve hit one of the exceptions below.
So clearly I’m still doing something wrong with regards swapping my textstorage
objects in and out of the textview.
Any further clues you can offer would be gratefully received,
Martin

That seems a little backwards to me.
NSLayoutManager is really the center of the Cocoa text architecture. It
manages the list of NSTextViews, the list of NSTextContainers (those two
objects are associated 1-to-1), and the NSTextStorage that will be rendered

I don’t know if it’s documented anywhere, but you can discover what it is by writing a tiny app that adds an observer for all distributed notifications of any time and logs them. or to send out a text/email/tweet when certain notifications are posted, etc. I would think this would be Generally Useful. Wish there were a way… It could be useful. But it would be a very different facility, since the data posted in the notification would need to be machine-readable not human-readable — instead of a localized string you’d want something like an NSDictionary with well-defined keys. (The types of notifications sent out would likely be different too. For example, there’s no point displaying a visible notification when Mail sends a message, but an internal notification would be useful.) Anyway, this facility already exists — it’s NSDistributedNotification. What you’re asking for is basically for more apps to support posting them, which isn’t a technical issue so much as one of evangelism. —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: UINavigationController subclass won't load its nib.
I think your approach is wrong. It doesn’t sound like you have a specialized navigation controller, but rather a navigation controller that has a specialized UI. The way to approach that problem is to load a UIViewController subclass with that logic in it, and create a UINavigationController with that custom view controller as its root view controller. If you have further specialized logic that needs to know about both the navigation controller and its view controllers, then you can create an additional class to manage that work, but you almost certainly don’t want it to be a navigation controller subclass.

Re: collection of applications
Seem to me that you are considering making an enterprise single sign-on portal. Of course you can combine everything into a single app, but a more graceful solution can exist. Just to correct a misunderstanding, iOS dyld can load dynamic libraries if carried as part of the application bundle (and there is a hack that allows on-the-fly patching of the in-memory libdyld to load libraries downloaded from any arbitrary address, but that involves lots of black magic and Apple can reject it if found out.) Also external binaries can be used - there is an App Store app called iSSH that carried its own signed version of PuTTY cross compiled for iOS. As mentioned, you can launch other apps by URL schemes. This is also a method of inter-app communication as you can encode data into the URL string. You can design a family of apps that requires a SSO and a SSO portal. When a client app is launched directly it redirects the user to the SSO portal, telling the portal who called it. The portal then redirects the user back to the app with whatever information needed for the session to continue after authentication. It seem to me that Facebook used this scheme in the wild (that is, Facebook app is the SSO portal and apps using Facebook SDK is signing on using Facebook app itself.)

Re: collection of applications
This is not new - it existed since iPhone OS 1.0. However by saying “can load dynamic libraries” does not mean you can actually use it in production code. Apple does not allow any dynamic libraries exist in App Store packages (“Nobody but Apple can put dynamic libraries onto iOS device) so the dynamic library support is pretty much restricted to jailbreak community. Multiple jailbreaks and jailbreak packages used this ability.
