使用Cocoa Touch教程：在iPhone OS上提取地址簿地址值 [英] Using Cocoa Touch Tutorial: Extract Address Book Address Values on iPhone OS

问题描述

我已经按照以下教程，在模拟器中它工作得很好，但是在我的手机上选择地址时，谷歌地图发布，我想我已经炒了我的大脑。我将它与NavBarContolloer结合使用任何帮助都会很棒。

I've followed the following tutorial, in the simulator it works great, however on my phone when select the address, Google maps launchs, I think I've fried my brain on this. I am using this in conjunction to a NavBarContolloer Any help would be great.

推荐答案

在

- [ABPeoplePickerNavigationControllerDelegate peoplePickerNavigationController：shouldContinueAfterSelectingPerson：property：identifier：]

您需要返回NO才能启动Google地图。返回YES将继续使用默认操作，该操作在设备上启动Google地图。

you need to return NO in order not to launch Google Maps. Returning YES would continue with the default action, which on the device is launching Google Maps.
