CALayer's geometryFlipped is initially reset to Layer-Hosting NSView's isFlipped when linked agains 10.8
I've noticed that if an app is built against ML SDK, the geometryFlipped property is initially reset to NSView's isFlipped. Initially means at some point after view is added to the hierarchy. By reset I mean it discrads previously set value. However it's not bound to the isFlipped property. You are free to change it after some time. Is it intended behavior?

default "synchronous" and "full_fsync" of Core Data Sqlite on iOS
Hi All, I read Apple's documentation "Core Data Programming Guide" recently. In chapter "Persistent Store Features" section "Configuring a SQLite Store’s Save Behavior" , they talked about different behavior of SQlite options "synchronous" and "full_fsync" on different version of Mac. However the default option on different version of iOS is not mentioned, Does anyone here have any idea about it ? It would be much better if I could know the way to verify your answer.

I tried both to return NO and to not overriding the method but it still wont open any window at start up. The method(s) are not even called..? I think it has something to do with 10.8 restoring the previous state but I'm not sure how to force it to open an window if there was no window at application exit. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Plan for persisting preferences on iOS applications
We're currently looking at expanding one of our applications from 1 office to up to 40. It's an app that needs an internal preference to be set and remembered through updates or reinstalls. Since (thanks to the joys of sandboxing), preferences can't be saved outside the app in the preferences folder, I'm expecting to either get a UUID, or MAC address of the device, registering it and the device's name off in a mySQL database and fetching this information on load every time and saving as a pList if the pList doesn't exist, or if the pList contents are different from what is fetched. It sure sounds like a valid approach, but is this the best approach? Since standard policy with many companies is that no corporate data can exist outside the corporate network, using iCloud is out of the question.

Well, according to the docs, the preferences folder is within the app. Therefore, when replacing the app, (which is a folder) the entire contents of the app would be expected to be replaced. To anyone who has been using a Mac since they came out and knows how folders work, this is the expected behaviour. Nothing I have read has told me otherwise. Why would an app's contents be preserved on a fresh install? And if they would be preserved on a fresh install, where is this documented so that we know where to find information like this.

The docs describe the sandbox configuration (or should) which does not say that preferences are inside the application, but rather inside the application's sandbox.

Apple's doc writers need to do a much better job of explaining that even though the app is sandboxed, the sandbox exists outside the application and the app and the sandbox folders sit next to it within a folder that holds them all. Or does it? Since the app itself is referred to as a folder and the Documents, Library and tmp folders for an app belong to that, it's not obvious that the folders sit within a folder that contains the app, but at the same level as the app itself. And with the removal of access to the /preferences folder, it is way too easy to make the assumption that it's impossible to save application specific data that will not persist if the app gets updated. Thank you for making me look at this again.

Looking at it from an educated developer perspective, I can see that the current docs make perfect sense. To those who have been using Macs for the past 25 years, but not explicitly coding in OC until the past few, there needs to be a little more detail. There is a nice illustration at the bottom of the screen here that shows the app structure: http://developer.apple.com/library/ios/#documentation/iphone/conceptual/iphoneosprogrammingguide/TheiOSEnvironment/TheiOSEnvironment.html When that illustration is not in front of you, the doc that I read 6 months ago shows the folders that the app has access to under the hierarchy of the app and since the app itself is a folder, it's all to easy to make the mental jump that those folders exist within the app itself. I'll try to find those docs and offer feedback to make things a little more clear.

Need help passing a Secure Bookmark to an XPC Service
Hi All,
I am sending a NSURL, encoded as a Secure Bookmark, from the main part of my
sandboxed application to an XPC Service that handles a specific subtask. The
data is making it across the interface, but when I try to resolve the bookmark
back into an NSURL, I get the following error:
10/24/12 5:15:18.908 PM com.einsteinslegacy.silica.silicaHelper: ---
bookmark error: Error Domain=NSCocoaErrorDomain Code=259 "The file couldn’t be
opened because it isn’t in the correct format." UserInfo=0x7faf418069a0 {}
Googling the text of the error message has not lead to any useful insights.
Here's what I'm doing:
• When a user selects a file, I create an object containing the URL and the
associated secure bookmark.
• I use NSKeyedArchive to create a data object, which I then pass to the XPC
service as a key-value pair in an xpc_dictionary.
• The XPC service receives the message, unpacks it and calls NSKeyedUnarchiver
to reconstitute the URL from the secure bookmark.
At this point, I check the length of the bookmark data. The value matches the
length of the originally encoded bookmark. However, when I try to resolve the
URL using the following line of code, I get nil.
self.url = [NSURL URLByResolvingBookmarkData: self.bookmark options:
NSURLBookmarkResolutionWithSecurityScope relativeToURL: nil
bookmarkDataIsStale: &isStale error: &bookmarkError];
The entitlements file used for the XPC Service is a duplicate of the main
application file. The XPCService dictionary in the service's info.plist has
"JoinExistingSession" set to YES, so I assume that both parts should have the
same set of entitlements.
Are there other factors I need to consider when passing secure bookmarks?
curiously,
douglas

You don’t need a security-scoped bookmark for this. Regular bookmarks carry
access to the file until the computer next reboots.

In dev and testing no problem was encountered but "in the wild" we have this crash deep within -[NSURL URLByResolvingBookmarkData:options:.]. The app was incorrectly signed due to a stuff-up with the developer ID certs which was resolved, but that won't help until we get an update published. What's annoying is that the bookmark resolving just crashes rather than handle the problem gracefully, and we're still not certain whether the incorrect signing is the real cause or not (the apps were signed, just not using the correct cert). This deep connection between parts of the OS that behave very differently according to the situation they find themselves in is a recipe for very hard-to-find bugs that easily escape QA. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I wasn't setting error to nil, I am now. However, all I do with the value of error is log it if the URL returns nil. While that could crash in the circumstances your post describes, that isn't where it appears to actually be crashing. (Unfortunately I don't have a stack trace handy). Do you know of a way to force this resolution to fail so I can test it? --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Cross-fading between layers
I'm surprised it worked at all under any version of OS X, since you set the current layer to the new layer before committing the transition! Since it sees the two layers are the same, there's nothing to change, so nothing happens (I think…) On Oct 18, 2012, at 10:50 AM, Gabriel Zachmann wrote: > About a week ago I have posted about my problem with (not) cross-fading Core > Animation layers in Mountain Lion. > > Perhaps, my post was too long ;-) > Perhaps I forgot to mention that I did google quite bit, but didn't > understand what the best solution would be in my case. > > So far, I am fading out an existing layer, and fading in a new layer by the > following 5 lines of code: > > [CATransaction begin]; > [CATransaction setAnimationDuration: fading_duration]; > [mainLayer_ replaceSublayer: currentLayer_ with: newlayer]; > currentLayer_ = newlayer; > [CATransaction commit]; > > This works fine under Lion, and it worked fine under Snow Leopard. > > It does not work any more under ML, i.e., the layers get replaced, but there > is no cross-dissolve effect. > > Apparently, a number of other people have a similar problem, but the > solutions some of them propose were not clear to me. > > Could some kind soul explain to me how to achieve the cross-dissolve effect > under ML? > > Thanks a lot in advance. > > > Best regards, > Gabriel. > > > ___ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/wsquires%40satx.rr.com > > This email sent to wsqui...@satx.rr.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Prevent NSSplitView from resizing when replacing sub views
Hello all, I have a view defined in NIB. In my code, I am replacing one subview of a NSSplitView with the NIB view. Unfortunately, NSSplitView resizes its subviews to satisfy the size of the NIB view, which makes the ui jumpy. Is there a way to resize the NIBView to satisfy the NSSplitView instead of the contrary? I am using auto layout so setting the frame of the NIB view directly might not be an option. Thanks!
