2 Beginner Bindings Questions
I have two instances of the same tableview and controller that I am keeping synchronised via bindings to a common array. I have this working, in that I can add items via a button in one view and the other view instantly updates. Same with deleting selected items using [arrayController delete] via a button in each view. However I am having great difficulty showing the same selection of items using bindings. I would basically like to select rows in one table and have the selection updated in the other. Pretty well everything I have tried either causes an exception or does nothing. In the TableView I have tried binding the SelectionIndexes using various combinations of the selection based Controller Keys with various Model Key Paths ( including none ). I have also done some things with the Selection Indexes in the ArrayController bindings as well. So my question is - just what combination is required to get this to work? My array is very simple with just some strings added. The tableviews are single column with description for the identifier and the table column is bound using arrangedObjects as the Controller Key and description as the Model Key Path My other question is related. I would like to enable the delete button only if there is a selection in the table. Again, I have tried binding the enabled property of the button to the controller with various combinations of Controller Key and Model Key Path, with no luck. I have also done some google searches but nothing of any real help. I am sure I'm missing something simple so any help here would be great! cheers, Peter___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Joining App Developer Program
Hi, I just enrolled into the iOS program and the we are trying to contact the legal representative took two weeks. The lady on the phone said there was a large queue causing the delay.

Now I've been waiting a week with no word, and I'm eager to start making any necessary changes to my app to support the app store.

UITouch's function locationInView not working with iOS4.2
Hello,
Why is it that UITouch's function locationInView not working with iOS4.2?
I have a table view with a UISwitch on each cell and added an action for a
value change event.
It was successfully running with iOS4.1 and below but with iOS4.2, it is not
working.
Do you have any suggestion how get a table view's row with a touch event? How?
Thanks in advance!
My code snippets are below:
CREATION OF UISWITCH:
snip
UISwitch *switchCtl = [[UISwitch alloc] initWithFrame:frame];
[switchCtl addTarget:self action:@selector(switchAction:event:)
forControlEvents:UIControlEventValueChanged];
snip
THE switchAction() FUNCTION:
- (void)switchAction:(id)sender event:(id)event
{
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView: self.tblView];
NSLog(@switchAction: x=%f, y=%f, currentTouchPosition.x,
currentTouchPosition.y);
NSIndexPath *indexPath = [self.tblView indexPathForRowAtPoint:
currentTouchPosition];
NSLog(@switchAction: indexPath.row = %d, indexPath.row);
snip
}

Angie

Set Icon For Document-Based Files

How do I change that standard icon into a custom one?

Re: UITouch's function locationInView not working with iOS4.2 (cont)
Reminding people that something is under NDA has never before been an issue in this forum (although Scott may also on occasion reply to the thread with that reminder personally to drive the point home officially). If it's not released software then basically it can't be discussed here, I would think anything unreleased is under NDA, but even were it not, you can't talk about it here, this forum is for software out in the wild, it's a public forum, it's available to all and it's indexed on the greater web. People have pointed to the forums before also, they are the right place to discuss anything non-public and it's no secret that they exist, you just have to be authorized to read them, reminding people of that has also never hitherto been an issue and that has always seemed eminently reasonable.

Re: Notifications on main thread
OK, I think I have managed to read the release note again using your interpretation, but I think I will follow your suggestion of filing a documentation enhancement request. However, I think their second bullet point Notifications posted through a queue might not ever be posted is still an important one though, that might be enough to rightly put people off using notifications for anything important. I would interpret their explanation as being compatible with a case where for example a notification posted just before a modal loop ended would evaporate into the aether (even though it was posted through the main thread's default queue and the main thread is still running). That sort of thing should probably put me off using them for many of the things I currently do... On 2 Nov 2010, at 18:44, James Bucanek wrote: Jonny Taylor mailto:j.m.tay...@durham.ac.uk wrote (Tuesday, November 2, 2010 11:07 AM -): Empirically that does seem to behave in a common sense manner. However, if we examine the wording of the release note I believe it is explicitly stating that this should NOT be relied on - i.e. posting a notification from a selector on the main thread does not guarantee that the registered notification callbacks will be executed on the main thread. The release notes state [my emphasis]: Notifications can be posted by any given queue ON A DIFFERENT THREAD THAN THE THREAD THE QUEUE IS A DEFAULT QUEUE FOR (when a queue is a default queue for some thread); ... I agree with you that the approach you and I are talking about seems to work in practice, and certainly seems like a logical approach, but somebody at Apple seems to have taken the time to write an obscure release note specifically discouraging such an approach. Jonny, I think you're reading too much into the statement made in the release nodes. If we assume that notifications are posted from the thread they are _enqueued_ from, then the wording of the release note is absolutely correct. It's a warning for those who would (rightfully, in my mind) assume that the notification would be posted in the thread associated with the run loop that the queue is connected to. What this footnote does NOT say is Warning, your notification will be posted via some random thread that you have no control over, which is how I think some people are interpreting it. I think this is because the release note is written from the perceptive of the queue. From the queue's perspective, notifications could be executed from any thread. But from the perspective of the enqueuer, the notification is always posted in its thread. I think it's clear from the document that notifications ARE posted from the thread that ENQUEUES the notification, NOT the thread that OWNS the queue's run loop. If you don't think that the documentation is clear about this point, file a documentation enhancement request. I've filed requests like this in the past, and have been almost universally reworded with improved documentation.

Re: [iPhone] HTTPS / client Certificate / configuration profile
Yes it works. Thanks for the hint. Safari first asks me to accept the server certificate. second step it warns me that the web site demands a client certificate and asks me to choose one from a list. once selected i am prompted for user name and password from the server. Which is the intended process. I get the proper challenge from NSURLConnection delegate selectors. somehow my application does not find the certificates when it is being challenged for the client certificate. I must be doing something wrong in the lookup. to be honest all this authentication is still a little blurry for me at this point. I understand the concept...where should i look up for the certificates/credentials... it is somewhere else than the keychain ? to query the keychain I currently use... [NSDictionary dictionaryWithObjectsAndKeys: (id) kSecClassIdentity, kSecClass, kSecMatchLimitAll, kSecMatchLimit, kCFBooleanTrue, kSecReturnRef, nil], [NSDictionary dictionaryWithObjectsAndKeys: (id) kSecClassCertificate, kSecClass, kSecMatchLimitAll, kSecMatchLimit, kCFBooleanTrue, kSecReturnRef, nil], both query come back empty. Added info: The Configuration profile's Identity is the same as the Bundle identifier and the Entitlements application-identifier and the keychain-access-groups as i read, the applications only access keychains for their access groups. if that makes a difference...

Re: Notifications on main thread
Jonny Taylor mailto:j.m.tay...@durham.ac.uk wrote (Wednesday, November 3, 2010 9:05 AM -): OK, I think I have managed to read the release note again using your interpretation, but I think I will follow your suggestion of filing a documentation enhancement request. However, I think their second bullet point Notifications posted through a queue might not ever be posted is still an important one though, that might be enough to rightly put people off using notifications for anything important. I would interpret their explanation as being compatible with a case where for example a notification posted just before a modal loop ended would evaporate into the aether (even though it was posted through the main thread's default queue and the main thread is still running). That sort of thing should probably put me off using them for many of the things I currently do... Jonny, I (finally!) found the NSNotficationQueue Warning that you're referring to. Reading it, I can see where the panic and confusion comes from. But I don't think the situation is as dire as some are making out. Sure, there are some VW-sized open manholes to avoid, or at least some things to consider when using notification queues. But I don't see many as show stoppers for the vast majority of solutions. Here's what the warning is (basically) saying: Notifications are queued and dequeued (i.e. posted) by run loops. Thus, in certain circumstances, the processing and posting of notifications may happen at unpredictable times on unpredictable threads. But unpredictable under certain circumstances doesn't mean random. What the release note is saying is that it's the run loop of the current thread (the one that sends -[NSNotificationQueue enqueueNotification:...]) is the one that's going to process the enqueue notification message. This has a number of ramifications, although the release note uses overly scary language (IMHO): 1) The run loop of the current thread is the one that's going to process the enqueue request. 1.a) The run loop must be running, and keep running, until the enqueue request is processed. 1.b) The run loop must be running in the correct mode for the enqueue request to be processed. 2) Enqueuing a notification may cause coalescing, or not. That means when the enqueued notification is processed, there may be other notifications before it that need to be posted first. If there are, those will be posted on the thread of the run loop that's processing the enqueued notification. So this explains ALL of the things that the release note worries about: Notification never been posted, notifications being posted on a different thread, notifications being posted by a run loop of a thread different than the default for that thread, not being able to guarantee the thread a notification will be posted on, and so on. But what the release note doesn't say is that almost all of these problems are problem only when you have multiple threads enqueuing notifications to a single notification queue. If all of the notifications come from a single thread, and that single thread has a running run loop (in the correct mode), none of these warnings apply. So if you enqueue all of your notifications on the main thread, everything gets enqueued, dequeued, and posted on the main thread. Easy peasy. The other situation that's perfectly manageable is multiple threads enqueuing notifications, where each thread has a run loop (running the appropriate mode). The solution is to simply NOT assume the thread the notification will be posted on. Write your code so that the notification methods are thread safe and you're done. I hope that helps.

Layout vs. Frame Rectangle
I am pretty sure the answer is no, but I was wondering if it was possible to programmatically obtain the layout rectangle as shown in Interface Builder in my own code outside of IB? I couldn't find anything, except for: http://developer.apple.com/library/mac/#documentation/DeveloperTools/Reference/NSViewIBAdditions_Reference/Reference/Reference.html but, as the documentation states, these methods are only relevant for IB plugins and I need the information outside of an IB plugin.

CALayer renderInContext: performance

Setting (not saving) NSPersistentDocument Metadata changes file Modification Date
In Core Data Programming Guide ▸ Using Persistent Stores ▸ Store Metadata, I read: Note that setting the metadata for a store does not change the information on disk until the store is actually saved. And indeed that is true. So I add my metadata, in my document-saving method, *before* invoking NSPersistentDocument's -saveDocument: or saveDocumentAs:, which does the actual saving. However, although the metadata does not get written to the disk by +[NSPersistentStoreCoordinator setMetadata:forPersistentStoreOfType:URL:error:], apparently the file modification time gets changed, because after doing so, and then invoking -saveDocument:, the dreaded warning sheet This document's file has been changed by another application since you opened or saved it shows its wretched face. So, I do this: • Read and remember the file's modification date (NSFileManager) • Set the desired metadata • Set the file's modification date back to the remembered value (NSFileManager) • Invoke -saveDocument: Voila - no more stupid warning sheet. Why does +[NSPersistentStoreCoordinator setMetadata:forPersistentStoreOfType:URL:error:] change the file modification time given that, per documentation, it does not modify the file? Is there a better way to do this? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
