ipad - “无法支持开发”iPad 5.1 + Xcode 4.3

Question

我正在使用 Xcode 4.3，当我的 iPad 与 iOS5.1 连接时，管理器确实识别出我的 iPad 但说

“无法支持开发”。

我尝试了另一台具有相同 iOS 的 iPad，没有任何问题。

有人有任何线索吗？

Answer 1

关闭设备，然后重新打开。

Answer 2

Powering on/off didn't work for me. However, I think there was some dirt or something in the 30-pin connector. I blew on it to clean it out, and voila, it worked.
