NSTerminateLater and thread
I would like my application executes a given task before the log-out. I almost succeeded but since this task could take a few minutes and since I have to launch it on a separated thread (so the user could stop it), I am getting some trouble. In the applicationShouldTerminate method, I know that the Quit has been invoked by the log-out thanks to the NSWorkspaceWillPowerOffNotification So from within applicationShouldTerminate I invoke: [self ExecuteLogOutTask]; return NSTerminateLater; In this case the task gets executed properly but the user cannot cancel it. The application looks unresponsive to the user. So I tried: [NSApplication detachDrawingThread:@selector(ExecuteLogOutTask) toTarget:self withObject:nil]; return NSTerminateLater; But I get a dialog saying: You haven't been logged out because the application MyAppLogOut failed to quit. Try logging out again And the ExecuteLogOutTask has not been called at all. If I return NSTerminateCancel I cancel the whole log-out, which is not what the user expects. So how to manage this case?

Re: Programmatically displaying UISplitViewController popover?
Which bit can't you do? Are you having trouble opening the popover (in which case you just want to call the code which would be called if you pressed the button, just call it programatically) or are you having trouble figuring out when your app is launched in portrait mode, which you could do by setting a flag in one of the application methods to say you just launched, and checking it when you get the viewDidAppear: call.

iOS: drawing the end of a CGPath differently
How would I go about drawing a terminus at the end of a path? I'm drawing a path in an overlay to a MKMapView, but I would like to somehow designate the end point of the path to differentiate it from the rest of the path. CGContextAddPath(context,path); CGContextSetRGBStrokeColor(context,0.0f,0.0f,1.0f,0.5f); CGContextSetLineJoin(context,kCGLineJoinRound); CGContextSetLineCap(context,kCGLineCapRound); CGContextSetLineWidth(context,lineWidth); CGContextSetShadow(context,offset_size,0.0); CGContextStrokePath(context); CGPathRelease(path); Is there some kind of CGHighlightEndPointOfPath() call or its equivalent? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

OS + iOS best practice
I hope this appropriate for this list, if not please accept my apologies. I've got a fairly basic core data app that I've written for personal use on my iMac. I'd like to have an iPad version as it would be very useful to have whilst I was mobile. (It's basically a customer/product database). Is there a best way to manage sharing the data between an OS and iOS version? I assume it will be possible as long as they use the same datamodel. I was thinking maybe some kind of dropbox sync would be best as it wouldn't depend on a network connection, and I wouldn't need to use both the mac an iPad versions at the same time. I have absolutely no idea how to do this though. I know some apps have built in dropbox sync but I fear it may be beyond me as I haven't found a handy tutorial anywhere.

Re: OS + iOS best practice
Could indeed be easiest solution ;) You could also look at how you serialize or save data for export / import between two environments. Just have it custom save out to a standard plist format or a simple xml schema. Then you can decouple that from the CoreData versioning and differences. Internally, for speed or what have you it could easily import to the CoreData model. However, a simple web app might be just as feasible. Depends on what interests you at this point.

In fact I would try to share all of the model-related code between the two apps, to ensure that all the ‘business logic’ [I hate that word] is consistent. The easiest way to share the data is to use the file transfer feature of iOS 4, which will let you clumsily use iTunes to copy files to and from the iPad. It looks really simple to implement — IIRC most of it is just declaring in your Info.plist that you support the feature, and then specifying a subfolder of your Documents folder where copied files will live. Dropbox sync is a lot smoother, of course. I am not sure if there is a convenient Cocoa library to use for that. Coding it yourself probably isn’t too hard if you know your way around NSURLConnection, especially if you want to ignore niceties like the ability to browse folders in the dropbox. In the long run this will be an excellent use case for CouchDB (a document-oriented data store that excels at syncing), but the iOS version of that is still very much beta, and there’s no high-level API for it yet that gives you anywhere near the convenience of CoreData.

Let’s rebound the requirements: * there’s a single user Core Data app * want an iPad version of the app * the two versions will sync up Given the requirements, and add the fact that I’m pretty sure that Dropbox would keep conflicted copies of any file around, so there is no fear for lost data, and you can probably merge anything… it’s probably a good fit. If you don’t pull in any external resources, for example pictures on the filesystem which are only referenced by path strings in Core Data entities, the only thing that needs syncing would be the .sqlite file and things can probably work.

Re: Programmatically displaying UISplitViewController popover?
So you have the bar button item and tapping it works; I believe tapping it just invokes its action on its target and there is no much wizardry in thaqt. Is the item we’re talking about the same item that the split view controller sends to you in -splitViewController:willHideViewController:withBarButtonItem:forPopoverController: ? If that is the case, does something along the line of [[item target] performSelector:@selector(action) withObject:item] work? -ev On Jun 4, 2011, at 02:40, Rick Mann wrote: On Jun 3, 2011, at 5:42 , Roland King wrote: Which bit can't you do?

Re: OS + iOS best practice
Thanks Sounds like dropbox would be a good fit, I'll download the ask and give it a go. My current mac app stores the data in a sqllite file that I'm hoping to just sync with dropbox. However it does currently also store images in a directory and just store the paths as string attributes. Not sure of the best solution for those. I'm not expecting to always have web access on the iPad when the app is running. The images would not change too often once the app is initialised with data. A dozen or so new ones a month, and from the iPad they would only need to be read. Perhaps I could store the SQLite file and the images in a directory that can be stored in the dropbox directory?

Re: NSTerminateLater and thread
Thank you Kyle, however, I realize, it's incredible there is no way to execute a task before quitting the app. I easily run a task at launch but I can't run a task before quit. The problem is that the task could a few minutes and the app should remain responsive to the user, in the best Mac tradition. I will struggle myself some day more on this issue.

Re: OS + iOS best practice
As for the SQLite file, I am never sure if Core Data’s OS X implementation and iOS implementation share the same format and will continue to be so, and it is surely a very strong and valid idea to just use an intermediate format you control, I’ve been bouncing them across OS X iOS with no problem… Note that Dropbox exposes directory hashes, so that might help with images. I’m not sure if referenced images would be updated at all — this can be a big problem if they can be updated outside the app and you need to handle that. For the record, going with Dropbox might not be very safe, could be not scalable at all, and might have security implications as Jeffrey pointed out. But it might work very well for your scenario. If you’re serious about making it robust, I still recommend that you create a tiny and dedicated web service for this app… -ev On Jun 4, 2011, at 04:23, Amy Gibbs wrote: Thanks Sounds like dropbox would be a good fit, I'll download the ask and give it a go. My current mac app stores the data in a sqllite file that I'm hoping to just sync with dropbox. However it does currently also store images in a directory and just store the paths as string attributes. Not sure of the best solution for those. I'm not expecting to always have web access on the iPad when the app is running. The images would not change too often once the app is initialised with data. A dozen or so new ones a month, and from the iPad they would only need to be read. Perhaps I could store the SQLite file and the images in a directory that can be stored in the dropbox directory?

Let’s rebound the requirements: * there’s a single user Core Data app * want an iPad version of the app * the two versions will sync up Given the requirements, and add the fact that I’m pretty sure that Dropbox would keep conflicted copies of any file around, so there is no fear for lost data, and you can probably merge anything… it’s probably a good fit. If you don’t pull in any external resources, for example pictures on the filesystem which are only referenced by path strings in Core Data entities, the only thing that needs syncing would be the .sqlite file and things can probably work. If this is not the case then a simple Web service would go a long way.

Dropbox has been quite safe and scalable in my experience. I’ve been using it for a lot of my data for two years, have never lost data or gotten files messed up, and I can’t think of the last time it didn’t sync in a timely manner. The security issues are overblown due to the recent fracas. Yes, your files could theoretically be accessed by their employees or requested by the FBI. The same thing is true of your email, your iDisk, your Google Docs/Sites/Spreadsheets, any software running on your hosted web space, and anything else you put up in “the Cloud”. If you’re super paranoid you can encrypt and decrypt the files locally; but then you run into the complications of key management and transfer … which is one of the reasons cloud services don’t go as far as to do this. But it might work very well for your scenario. If you’re serious about making it robust, I still recommend that you create a tiny and dedicated web service for this app… I understand your point, but in practice, a service designed and run by professionals is going to be more reliable than a quickie web-app cobbled together in your spare time.

Multi-OS API Question
Hello,
I'm using some API's which are only available on 10.5 and above but I want to
compile my app to run on 10.4 and higher. How can I include multiple bits of
code so that if the system is running 10.4 it will run Code A and if 10.5 and
higher run Code B?
Example
if ( os == 104 ) {
// Run 10.4 Code
} elseif ( os = 105 ) {
// Run 10.5 and higher API
}
Thanks,
Charles___

Is the item we’re talking about the same item that the split view controller sends to you in -splitViewController:willHideViewController:withBarButtonItem:forPopoverController: ? If that is the case, does something along the line of [[item target] performSelector:@selector(action) withObject:item] work? Doing that works, it just strikes me as a hack.

Re: NSTerminateLater and thread
Besides from the fact I didn't care about the aborted logout, I was wrong anyway due to bad memory :( But you can bring up an application modal window after detaching the secondary thread in applicationShouldTerminate, giving the user options like cancelling, showing a progress indicator etc.. Repeatedly call runModalSession until the task is finished or the user cancelled. This worked fine for me in a similar situation. I guess a logout will time out anyway if the task takes too long.
