objective c - NSCoding Serialization of iPhone NavigationController stack -

Edit: I guess something that has helped found I retained Ivar "stack" and now it seems to work has serializing without

I have several custom NSObject classes issue. Now I want to sort my navigation controller stack. To regenerate the navigation tree, only each view controller needs to save some properties. I implemented the NSCoding protocol in NSData viewcontrollers, and successfully coded them and saved in the disk.

When I have the right number of attempts to stack loads, resulting array objects, but I take when I try to set the scene controller array getting EXC_BAD_ACCESS errors? I'm just going the wrong way about it

  // AppDelegate.m - (minus) loadDataFromDisk {NSString * libraryPath = [NSSearchPathForDirectoriesInDomains (NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex: 0]; NSString * programDataPath = [Pustkalypat Stringbapansetingpathkanpani: @ "Programdetadeta"]; NSDTA * Programdata = [[NSDTTA Alloc] Init with contentofffile: ProgrammapPath]; NSKeyedUnarchiver * Decoder = [[NSKeyedUnarchiver alloc] initForReadingWithData: ProgramData]; // stack header / stack = [Decoder decodeObjectForKey: @ "stack is a temporary array declared"]; Stack = [[decoder decoded objectForcae: @ "stack"] retained]; // maintains fixes? Seems to work [decoder release]; } - (bool) Application: (UIApplication *) application didFinishLaunchingWithOptions: (NSDictionary *) launchOptions {// defaults for optimization after launching application [window addSubview: [navigationController view]]; [Window-making and knowledgeable]; NSLog (@ "% @", self.navigationController.viewControllers); If ([stack count]> 1) {self.navigationController.viewControllers = stack; [Stack release]; // has been previously preserved) Yes;  

}

I do it after-disk Drishykantrolr stack Loading is obviously disappearing if you do not give data to an immediate retained property.
