  • Why isnt my data persisting with nskeyedarchiver?

    - by aking63
    Im just working on what should be the "finishing touches" of my first iPhone game. For some reason, when I save with NSKeyedArchiver/Unarchiver, the data seems to load once and then gets lost or something. Here's what I've been able to deduce: When I save in this viewController, pop to the previous one, and then push back into this one, the data is saved and prints as I want it to. But when I save in this viewController, then push a new one and pop back into this one, the data is lost. Any idea why this might be happening? Do I have this set up all wrong? I copied it from a book months ago. Here's the methods I use to save and load. - (void) saveGameData { NSLog(@"LS:saveGameData"); // SAVE DATA IMMEDIATELY NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *gameStatePath = [documentsDirectory stringByAppendingPathComponent:@"gameState.dat"]; NSMutableData *gameSave= [NSMutableData data]; NSKeyedArchiver *encoder = [[NSKeyedArchiver alloc] initForWritingWithMutableData:gameSave]; [encoder encodeObject:categoryLockStateArray forKey:kCategoryLockStateArray]; [encoder encodeObject:self.levelsPlist forKey:@"levelsPlist"]; [encoder finishEncoding]; [gameSave writeToFile:gameStatePath atomically:YES]; NSLog(@"encoded catLockState:%@",categoryLockStateArray); } - (void) loadGameData { NSLog(@"loadGameData"); // If there is a saved file, perform the load NSMutableData *gameData = [NSData dataWithContentsOfFile:[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"gameState.dat"]]; // LOAD GAME DATA if (gameData) { NSLog(@"-Loaded Game Data-"); NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:gameData]; self.levelsPlist = [unarchiver decodeObjectForKey:@"levelsPlist"]; categoryLockStateArray = [unarchiver decodeObjectForKey:kCategoryLockStateArray]; NSLog(@"decoded catLockState:%@",categoryLockStateArray); } // CREATE GAME DATA else { NSLog(@"-Created Game Data-"); self.levelsPlist = [[NSMutableDictionary alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:kLevelsPlist ofType:@"plist"]]; } if (!categoryLockStateArray) { NSLog(@"-Created categoryLockStateArray-"); categoryLockStateArray = [[NSMutableArray alloc] initWithCapacity:[[self.levelsPlist allKeys] count]]; for (int i=0; i<[[self.levelsPlist allKeys] count]; i++) { [categoryLockStateArray insertObject:[NSNumber numberWithBool:FALSE] atIndex:i]; } } // set the properties of the categories self.categoryNames = [self.levelsPlist allKeys]; NUM_CATEGORIES = [self.categoryNames count]; thisCatCopy = [[NSMutableDictionary alloc] initWithDictionary:[[levelsPlist objectForKey:[self.categoryNames objectAtIndex:pageControl.currentPage]] mutableCopy]]; NUM_FINISHED = [[thisCatCopy objectForKey:kNumLevelsBeatenInCategory] intValue]; }

  • How can I make my Video play as soon as the page loads

    - by bill
    im lost here, need some help for something probably very simple: I have embedded a swf object to play an flv file. i want the video to play as soon as the page loads rather than requiring the viewer/user to have to click the play button to see the video. I'm not sure if it is the swf file, the script or the javascipt file that has to be edited, and with what code. thanks

    - by Jacob Relkin
    Hi everyone, I lost over 35 hours' worth of code today. I don't know how it happened, but it just did. And I'm extremely upset about it. I learned the hard way that version control / backups are the most important. Anyone want to share your similar experiences?

  • Why are my images compressed?

    - by Johnny
    I'm using layout xml file for the UI. But the images are compressed and the qualities have lost in some level. My code is like this: <ImageView android:layout_width="480px" android:layout_height="717px" android:layout_x="0px" android:layout_y="45px" android:scaleType="fitXY" android:src="@drawable/e4" /> The drawable is actually 480x717. What's the problem here? Is it due to the fitXY?

  • Delete document with an empty ID

    - by Damien MATHIEU
    Hello, I have a CouchDB database in production. One of the documents has been edited (in Futon by an other developer). And it's lost it's ID (don't ask me how he did it). So now the document's id is an empty string, which makes it impossible to edit or delete via Futon. Is there a way I could hack into CouchDB to delete that document anyway ?

    I am looking for a simple tool that generates a catalog of all used action methods, values and bindings. I'm working on a big JSF/RichFaces project and I have lost the overview of the used links to the beans.

  • What are the implications of multi-tasking in iOS 4.0 for developers?

    - by MrDatabase
    I just watched this video from Apple that shows multi-tasking on the new iPhone (running iOS 4.0). What are the implications of multi-tasking to developers? Include both positives and negatives. For example what happens if the user decides to launch two resource-intensives apps at the same time, one of the apps crashes and progress in a game (for example) is lost. Should developers be considering this when writing apps for the new OS and phone?

    Apologies if the question sounds silly, I was following experts in SO and trying some examples myself, and this is one of them. I did try the search option but didn't find an answer for this kind. class A { public: A(){cout t; t.push_back(A()); // After this line , when the scope of the object is lost. } Why does the destructor of the class called twice ?
