将外部硬件连接到iPhone的唯一受支持方法是通过iPod附件协议(通过30针连接器).该程序的详细信息位于 http://developer.apple.com/ipod/accessories.html .这不是一个免费程序，并且30针连接器仅支持某些功能，但这是当今唯一可用的选项.
The only supported way to connect external hardware to the iPhone is through the iPod accessory protocol, through the 30-pin connector. Details on that program are at http://developer.apple.com/ipod/accessories.html. It isn't a free program and the 30-pin connector only supports certain features, but it's the only option available today.
