这是一个初中学生用一个月时间自学Objective-C以后开发的作品，一个类似酷狗的iPhone在线音乐盒。

因为被AppStore魂牵梦绕的，所以去年12月30号斥资xx大洋买了一台macbook，立刻投入到了神奇的objective-c世界中了。
在 没有任何c语言基础的情况摸索着前进，到目前已经差不多理解了一些重要概念，比如类，NSxx，内存管理，继承，间接。自认为我的学习速度还是挺快的，不 过毕竟是有object pascal的基础支撑。所以学起来并不是很吃力。
本来是想做一个类似于酷狗的iphone平台的音乐软件的，不过在昨 天晚上正式宣布放弃了。原因是一、我的技术还不够成熟，在线播放总不够完美(也许和我的性格有关，追求完美吧)。二、最重要是我认为自己高估了这产品的市 场前景。三、我有了更好的创意。所以呢，这个半成品就开源出来了。花了5个晚上外加一个周末的时间吧。其实没什么技术含量，相对来说，有点“技术”含量的 也就是三个函数了，用来从百度的搜索引擎页面中抓取信息，和解密百度的mp3地址编码。写的仓促了，毕竟初三了不能有很多时间来编程了，家里总是有意见， 唉唉。主要也是因为我文化课上的精力放的太少了。今天刚考完期末考试，虽然自我感觉不错，但是通常情况下，就见鬼的是，结果都超出我的自我感觉的。当然是 负面超出了。
