Re: iOS when is my app launched
Hey Dave, I'm talking about the Carbon equivalent of processLaunchDate in the ProcessInfoExtendedRec. This is the actual date time that the process launched. I want to use it to give my game's splash screen a consistent amount of time on screen. Here's how: I set the Default.png to the splash screen and immediately show the same image when my app launches. I then check the launch date to determine how much time it has shown and add x number of seconds to that. I know that this information is available via the ps command, so I could just resort to that, but I was hoping for a nice, clean, api way of doing it.

Using NSKeyedArchiver to save and restore state on iPhone apps
As many of you know, saving and restoring complex navigation hierarchies on the iPhone can be a real chore. So, I had this brilliant idea of setting up my app delegate like this: applicationDidFinishLaunching if userdefaults contains an archived navcontroller unarchive controller and retain else load nib with controller and retain add navcontroller view to window applicationWillTerminate archive nav controller and save to user defaults and then make all of my view controllers NSCoding compliant In theory, the archived navcontroller should contain my complex view controller hierarchy and all of the related views, so this should work. However, when I unarchive and add to view to the window, the subviews rarely have all of their values set correctly despite being supposedly NSCoding compliant. (For example, I have a button that fails to have it's target and action set) Am I missing something here or is this just buggy NSCoding compliant code on apple's part?

Re: Using NSKeyedArchiver to save and restore state on iPhone apps
This is separate from my model. This is the restoration of the view and controller hierarchy that is expected of iPhone apps when they startup. Restoring this can be incredibly complex when you have lots of view controllers including nav controllers, tab bar controllers, and modal controllers all stacked up. All of these are NSCoding compliant, which means that if I archive it, I should be able to unarchive it and get the exact state back (subject to conditional archiving, etc...) as long as I archive a complete object graph. Clearly, if there are any connections in your nib that connect to proxy objects (or the file's owner), you'd have to restore them yourself since you aren't loading from the nib. Storing the version of the app that saved the hierarchy would solve any issues related to that. Note, I've written tons of code to manually restore the hierarchy for other apps, I'm just trying to be clever and to save myself a bunch of complex coding (that easily gets out of sync with how your hierarchies can be stacked) this time... :) Jason On Feb 10, 2010, at 3:12 PM, Jens Alfke wrote: On Feb 10, 2010, at 10:40 AM, Jason Bobier wrote: In theory, the archived navcontroller should contain my complex view controller hierarchy and all of the related views, so this should work.

I don't think it should be necessary, either: it's a violation of MVC. The persistent data is the model; that's what you want to save. The views are configured at runtime to reflect the state of the model. One practical problem with your approach would be if you ever change the design of your view hierarchy in a future release. Now you have a complex schema-migration problem when existing users launch the new version of the app and load an obsolete view hierarchy. —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Using NSKeyedArchiver to save and restore state on iPhone apps
Yes, you have to account for any references into the unarchived graph that objects not included in the graph hold. In my case, this should be as simple as removing the navcontroller view from it's superview.

Re: Using NSKeyedArchiver to save and restore state on iPhone apps
Hey Ricky,
I'm strictly attempting to archive the controllers and views hierarchy starting
from the navcontroller. My data model is quite separate from all of this.
I've often done similar things to what you recommend, but complex interfaces
often include tab controllers, nav controllers, modal views, etc..., storing
the precise order of all of these along with the related metadata of all of the
controls is a pain and prone to error.
This idea came about because I was annoyed at having to do it again and
realized that everything that I wanted to store was NSCoding compliant, which
means that it should be archivable. It appears that some of the NSCoding
compliant objects aren't completely restorable tho. :-/

You don't want to take this approach at all.
The proper thing to do is to archive model data (as others have pointed out).
Note that this will now also be faster too since it will be a much smaller
data set.
For nav-based apps, this set of data often includes a screen ID of what
screen the user left off at. Upon app launch, you can basically just push
whatever screen you need to on the nav controller's stack.
This is exactly what I do in my own iPhone OS apps. I also have an
infrastructure to pass an NSDictionary filled with parameters as users hop
from screen to screen.
This allowed me to do stuff like this:
In MyScreenA...
- (IBAction)someAction:(id)sender
{
NSDictionary* = parameters = ...;
[self pushScreen:MyScreenBID withParameters:parameters animated:YES];
}
If users exit the app while on Screen B, I simply store the fact that I was
on that screen (and any other metadata I need to preserve selections, scroll
position, etc.)
Then, on app launch, if such a freeze-dried state exists, I ultimately build
up a set of parameters just like I did in the action method above. Then push
the appropriate screen with those parameters (and set animated flag to NO).
This will give the appearance of the app launching directly to the screen the
user left off.
But, under the covers, this is what actually occurs on app launch:
- app launch routines
- nav controller created; main nib loaded and set as top view
- code that senses you have a saved state
- push appropriate view controller to go to last used screen
All the standard nib-loading occurs and things just work.

Don't run it until the distant future; that'll cause the call to
block until some time in 400X, by which time you probably won't be
using your current Mac anymore. :) Instead, you should run shorter
intervals (like a second from now), and if you need NSEvents to
trigger during the time, then you should probably use -
[NSApplication nextEventMatchingMask:...] instead with dequeueing.
That method also runs the specified run loop.

Re: best way to determine if portion of window is visible?
Hey Andy, It's not really the cpu cycles that I'm worried about. It's how quickly a large number of windows closes. I'm fading each window for 1/2 second, in order of appearance. It looks really nice, but there isn't really a need to fade the windows that aren't visible and in fact, causes it to appear as if nothing is happening if a large number of non-exposed windows are faded before the exposed ones are.

Re: best way to determine if portion of window is visible?
Hi Mike, I'm using an NSViewAnimation to fade the windows, which I suspect uses the alpha channel. A window close is nearly instantaneous, so I'm not worried about the tiny window between when I check to see if the window is exposed and when it closes. Of course, because of the transparency of the covering windows, it is even more difficult to know whether the window is exposed or not. :-) Jason On Aug 15, 2008, at 6:07 PM, Michael Ash wrote: On Fri, Aug 15, 2008 at 2:18 PM, Jason Bobier [EMAIL PROTECTED] wrote: Hey folks, I'd like to fade my window out if any portion of it is visible to the user, otherwise I simply want to close it for speed.

If you're fading out the window using setAlphaValue: then it's likely the window server will realize when your window can't be seen anywhere and will be smart enough not to redraw anything, saving you from having to do any work. I don't know if any way to find out for yourself, and indeed it's kind of tough because the user could easily expose your window in between your check and the action you take based on it.

NSSound won't play wave files???
Has anyone else had issues playing wave files with NSSound? Not only
does it refuse to play the file (even tho I can open it with the

doesn't make a sound. AIFF files seem to play just fine. Here is the

success = [sound play];

}
@end
Very straight forward. The sound allocs and inits just fine and
success is YES after play is called. Not only does it fail to make a
sound, but it also fails to call my sound finished delegate.
Looking in the Console, I get this mysterious error:

Re: NSTask(syslog)-NSPipe-NSFileHandle-readInBackgroundAndNotify buffers
Hey Ken, I was originally going to use the ASL api, but it seems to require polling. Looking through the asl code, I noticed that the syslog command didn't poll on Leopard and between that and the different ASL_KEY_TIME formats on Tiger and Leopard, I decided to use the syslog -w 5000 -F raw -u -k mykey command and just parse the output. Polling the syslog database seems rather horrendous even if I was able to filter out the previously received entries (which doesn't seem possible because Tiger's ASL_KEY_TIME isn't comparable and ASL_KEY_MSG_ID only appears in Leopard). Any other thoughts? Jason PS, I read the Domain of the Bored ASL stuff before I started and it saved me countless headaches. :-) On Jun 11, 2008, at 5:05 PM, Ken Thomases wrote: On Jun 11, 2008, at 3:10 PM, Jason Bobier wrote: The issue that I'm having is that I'm using NSTask to create a syslog process with the -w option to continually parse specific syslog entries.

I believe that this is out of the control of your Cocoa process. It's under the control of the child syslog process. It might be changing its behavior based on whether its output is going to a tty device, but I'm not sure. You should consider using the ASL (Apple System Log) API, instead. It's Apple's more modern replacement for syslog. For backward compatibility, I believe it's hooked into syslogd, but ASL is the native logging facility. There's a great series of blog posts about ASL here: http://boredzo.org/blog/archives/2008-01-19/next-week-apple-system-logger .

Re: Unvending a distributed object
Yes, that is how you do it. Jason On Jun 11, 2008, at 7:09 PM, Ken Thomases wrote: On Jun 11, 2008, at 6:05 PM, Mike Manzano wrote: Does anyone know how to unvend an object?

Contrary to that linked post, I would expect that setRootObject:nil would do it. However, I haven't investigated with any rigor. Have you tried it and found it to not work?
