我使用 android cocos2d 计算游戏项目的分数，在该游戏中完成第一级后进入下一级别，所以我想存储第一级分数并添加下一级分数。我如何将分数存储在 android-cocos2d 中。

请您参考如下方法:

使用NSKeyedArchiver类来存储，这里有一个例子:

------------ 写

        // get allowed save paths 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
        // string for the default path 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
        // full path plus filename for save game 
NSString *gameStatePath = [documentsDirectory stringByAppendingPathComponent:@"gameState.dat"]; 
        // storage for game state data 
NSMutableData *gameData = [NSMutableData data]; 
        // keyed archiver 
NSKeyedArchiver *encoder = [[NSKeyedArchiver alloc] initForWritingWithMutableData:gameData]; 
        // encode all variables we want to track 
                 [encoder encodeObject:[player inventoryDict] forKey:@"playerInventoryDict"]; 
                 [encoder encodeObject:[player equippedDict] forKey:@"playerEquippedDict"]; 
                 [encoder encodeInt:[player initialActionPoints] forKey:@"playerInitialActionPoints"]; 
                 [encoder encodeInt:[player actionPoints] forKey:@"playerActionPoints"]; 
                 [encoder encodeInt:[player experiencePoints] forKey:@"playerExperiencePoints"]; 
                 [encoder encodeInt:[player xpNextLevel] forKey:@"playerXPNextLevel"]; 
                 [encoder encodeBool:[player isThinking] forKey:@"playerIsThinking"]; 
        // finish, write and release the encoder 
[encoder finishEncoding]; 
[gameData writeToFile:gameStatePath atomically:YES]; 
[encoder release];

            // string for the default path

            // full path plus filename for save game 
    NSString *gameStatePath = [documentsDirectory stringByAppendingPathComponent:@"gameState.dat"]; 
            // storage for game state data 
    NSMutableData *gameData = [NSMutableData data]; 
            // start the decoder 
    NSKeyedUnarchiver *decoder = [[NSKeyedUnarchiver alloc] initForReadingWithData:gameData]; 
 
            // start with player data 
    PlayerEntity *player = [PlayerEntity player]; 
 
        // variables from the PlayerEntity Class 
player.inventoryDict = (NSDictionary *)[decoder decodeObjectForKey:@"playerInventoryDict"]; 
player.equippedDict = (NSDictionary *)[decoder decodeObjectForKey:@"playerEquippedDict"]; 
player.initialActionPoints = [decoder decodeIntForKey:@"playerInitialActionPoints"]; 
player.actionPoints = [decoder decodeIntForKey:@"playerActionPoints"]; 
player.experiencePoints = [decoder decodeIntForKey:@"playerExperiencePoints"]; 
player.xpNextLevel = [decoder decodeIntForKey:@"playerXPNextLevel"]; 
player.isThinking = [decoder decodeBoolForKey:@"playerIsThinking"]; 
 
        // release the decoder 
[decoder release];
