Lbale显示“选择频道”

Tableview用来显示频道列表

知识要点

组件：

ImageView

TableView

TableViewCell

Progress

Label

Button

MediaPlayer

知识点：

视图之间的跳转，传参，回跳

协议

异步获取数据

Json解析

动画效果

豆瓣API

频道列表

歌曲列表

http://douban.fm/j/mine/playlist?channel=0

频道列表的json数据参考


{"channels": [{"name_en": "Personal Radio","seq_id": 0,"abbr_en": "My","name": "私人兆赫","channel_id": 0},{"name": "华语","seq_id": 0,"abbr_en": "","channel_id": "1","name_en": ""}]}


歌曲列表的json数据参考
