Research And Implement Of Self-organized Expeditions

China’s tourism industry has undergone enormous changes in the last five years. The first generation of the business was represented for offline travel agencies, whose store location largely determined their economic benefits. With the development of the Internet, Tuniu, as the representative of the second generation, operate the company through its own website that allows users to book online manner Offered registration, in this way breaking the traditional concept of a geographical area, and achieved great commercial success. Widespread popularity of smart phones is driving the tourism industry further upgrade. More and more young people are choosing the free exercise of the way travel, and smart phones map services, trip planning software such as the free exercise of ways to make it easier to achieve.This thesis focuses on the design and development of the commencement of the trip planning tools. First introduced the project background and projects objectives. Then outlined the main technical project development need, including iOS operating system introduction, XCode which is development tools, Cocoa framework, KVC and KVO technical standards and concurrent technology. Article elaborated on the needs of various modules of the software system, focusing on the function and implementation. The basic module is divided Registration System module, the trip show/editing module, travel recommendation module, sharing module. In this thesis, wherein the stroke data structures, code module structure has been described in detail. Meanwhile, the detailed description of the data structure to add to the stroke-based, delete node location algorithms and code. Then the difficulties in implementation of the system are described. Explain the difficult part of the detailed analysis of the common synchronization strategy classification, as well as the advantages and disadvantages of each strategy, and then tells the story of this project travel data in the client and server-side synchronization strategy design. Finally, the paper summarizes the future development of the project.This paper describes the trip planning tool designed to help users to edit travel itinerary. I believe more and more people will choose the free exercise of the way travel, and the trip plan tool will play an increasingly important role. This project is our entrepreneurial projects, is currently in the process of Online.
