Cocos2D编程Xcode读取文件代码及其注释

-(id) init
{
    // always call "super" init
    // Apple recommends to re-assign "self" with the "super" return value
    if( (self=[super init])) {
        //step1：创建并获得一个指定文件路径test
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSLog(@"Documents文件路径：%@",documentsDirectory);
        NSFileManager *fileManage = [NSFileManager defaultManager];
        NSString *myDiretory = [documentsDirectory stringByAppendingPathComponent:@"test"];
        BOOL ok = [fileManage createDirectoryAtPath:myDiretory attributes:nil];
        NSLog(@"test文件路径：%@",myDiretory);
        //step2：设置需要读取的文件的绝对路径
        NSMutableString  *myfilePath = [NSMutableString stringWithCapacity:100];
        [myfilePath appendString:myDiretory];
        [myfilePath appendFormat:@"/player2.png"];//Three.txt"];
        NSLog(@"myfilePath文件路径：%@",myfilePath);
        //step3：读取在test下的一个不在压缩包的图片文件  <路径怎么写:这里将myDiretory进行字符串的转换然后将其进行加减就可以了>
        NSData *data = [fileManage contentsAtPath:myfilePath];
        NSLog(@"文件内容二进制形式：%@",data);
        //step4：将这个不在包内图片内容进行显示
        //这里已经将图片给剪切了
        CCSprite *sprite = [CCSprite spriteWithFile:myfilePath rect:CGRectMake(0, 0, 28, 28)];
        sprite.anchorPoint = ccp(0, 0);
        [self addChild:sprite z:0];
    }
    return self;
}

以上代码详细的对怎样读取一个资源文件做了介绍，希望对大家有帮助。
