本文介绍了iOS应用中游戏存档和加载的实现方法。通过使用NSKeyedArchiver和NSKeyedUnarchiver，可以在游戏进入后台时保存游戏状态，并在下次启动时恢复游戏进度。

解档

//AppDelegate.m
@synthesize window=_window;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   
    NSString* gameArchivePath = [self gameArchivePath];
    OneGame* existingGame;
    @try {
        existingGame = [[NSKeyedUnarchiver unarchiveObjectWithFile:gameArchivePath] retain];
    }
    @catch (NSException *exception) {
        existingGame = nil;
    }
    [gameController setPreviousGame:existingGame];
    [existingGame release];
    
    //设置为主窗口并显示出来
    [self.window makeKeyAndVisible];
    return YES;
}



//GameController.m
-(void)setPreviousGame:(OneGame*)aOneGame{
    previousGame = [aOneGame retain];
    
    if (previousGame != nil && [previousGame remaingTurns] > 0){
        [continueButton setHidden:NO];
    } else {
        [continueButton setHidden:YES];
    }
}

存档

//AppDelegate.m
//进入后台游戏存档
- (void)applicationDidEnterBackground:(UIApplication *)application
{
    NSString* gameArchivePath = [self gameArchivePath];
    [NSKeyedArchiver archiveRootObject:[gameController currentGame] toFile: gameArchivePath];
}
