使用Cocoa Touch教程：在iPhone操作系統上提取地址簿地址值

Question

我按照以下教程，在模擬器中工作很好，但是在我的手機上選擇地址時，Google地圖啓動，我想我已經炒我的大腦在這。我將這個與NavBarContolloer結合使用任何幫助都很棒。

下面的代碼：

在

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

你需要返回NO在爲了不啓動Google地圖。返回YES會繼續執行默認操作，該操作會在設備上啓動Google地圖。
