I'm fairly new to programming for the iPhone. So, please excuse me for not fully understanding this issue.
我对 iPhone 编程还很陌生。所以，请原谅我没有完全理解这个问题。

Xcode will tell you what you're missing. Choose View > Navigators > Show Issue Navigator, then turn down all of the disclosure triangles:
Xcode 会告诉您缺少什么。选择“视图”>“导航器”>“显示问题导航器”，然后调低所有显示三角形：
Note that you declared a method named Contact:, but you implemented a method named Contact. The colon is part of the method name. You can't omit it.
请注意，您声明了一个名为 的方法Contact:，但您实现了一个名为 的方法Contact。冒号是方法名称的一部分。你不能省略它。
