Thus to develop the iOS apps is very important. The subject is brought up under this background, an iOS app which provides personalized contacts management. This thesis first introduced the subjec’s research background, meaning and content, the development of iOS, and the related technology about developing apple on iOS. In the meantime it also introduced Contact’s function and requirement, the detailed analysis on all functions, using MVC design mode together with Cocoa protocol and proxy mode, propose of the software architecture, it also describes each module’s design ideas and the technology to implement. It also introduced the run result and analysis, least but not last, it summarizes the whole subject and the outlook of the next step of research.The Contacts app described in this thesis is already finished and in use commercially. The function of this app exceed the one comes with the phone, it can help you to each contacts quickly, backup contacts and never get lost, provide free text function.
