The Development Of Personal Health Management System Client Based On IOS

Health management is a process of comprehensive management for factors which affect t he person or people’s health. Its aim is to mobilize the enthusiasm of individuals, groups and social, make use of limited resource to get the best health effect. At present, most of the existi ng health management systems apply PC as a carrier. In recent years, mobile devices, such as smart phones and tablet PCs, has become increasingly popular, that it will promote the development of health management to spread health management services to the mobile platform. The personal health management system client based on iOS is developed for iPhones and iPads, which are very prevalent now, and because the carrier is small and lightweight, its convenience and flexiblity has been greatly improved.Designed three-tier client structure which made up by presentation layer, control layer and data layer, and which is based on MVC model and functional modules of client. Designed the data layer, and divided it into four parts of network module, data access module, local database module and data security module. Designed the local database from the three aspects of conceptual model, organizational model and physical structure. Designed the data browsing capabilities in the three aspects of text display, image display and graph drawing.Adopting the notification mechanism of iOS system to implement the real-time monitoring of network status. Using the data security mechanisms based on RSA and AES encryption algorithm to ensure the safety of the communication between client and server. Using controllers such as navigation controller, table view and image view to complete view switch and data display. Applying view zooming and view rolling to improve the readability of data and the flexibility of display. Utilizing the technology of Quartz2D to draw health trend figures.Currently, the prototype of personal health management system client has been completed and trial operation has achieved the desired results, which indicate that overall system design is reasonable and the solutions to problems are effective and feasible.
