问题 I'm developing an iOS app where it requires to use EWS managed APIs. I've searched the web thoroughly but I'm not getting any success. It requires to get and set user's profile information, i.e. User's display name, company name, phone number etc. 回答1: EWS Managed API is for Windows desktop apps only.

问题 Since the update of Xcode 5.0.2, the address book of the simulator is empty. Apparently, if one wants to test address book code on the simulator, one has now to enter the test contacts by hand every time the simulator is reset. Earlier one had the standard test addresses "John Appleseed" etc. Is there any simpler way to use test contacts on the simulator? PS: I want to give credit to DipakSonara and Paaske. I had the same problem with my code that worked earlier fine, and I had never thought
