xcode4 – 未调用方法cellForRowAtIndexPath方法

我是iOS的初学者,在桌面视图的帮助下创建了一个应用程序.我只是运行我的应用程序,在运行应用程序时,应用程序不会调用方法cellForRowIndexPath.我使用Json作为Web服务.在输出屏幕中,显示解析数据但不会在模拟器中显示.我把断点,我明白没有调用cellForRowIndexPath路径.我将datasourse和数据委托拖到xib文件的文件上.但没有任何事情发生……桌面视图显示但没有内容……我搞砸了..任何人请帮帮我…

我想你还没有在你的.h文件中添加UITableviewDataSource和UITableViewDelegate
