I. INTRODUCTION
iOS is the operating system that runs on iPad, iPhone, and
iPod touch devices. The operating system manages the device
hardware and provides the technologies required to implement
native apps [1].
The application development based on iOS turn s to be a
research focus and trend with the great success of iPhone and
iPad. During developing these applications, data tr ansmission
and data storage are two main problems to be solved. In this
paper, taking the ordering system based on iPad as an example,
it offers a solution to these problems.
The ordering system based on iPad client can achieve quick
and easy ordering in contr ast to the tr aditional ordering by
paper and pen. A lot of human resources and menu
manufacturing cost can be saved for enterprise; the overall
operating effi ciency can be improved. In this paper with the
ordering system as an example, the data communications
solution between the web server and the iOS client and the data
storage solution will be proposed. Through testing by
downloading the application to several tr ue iPad machines, this
ordering system can be proved to have practical and
development value, and the design ideas of the system may be
used extensively in related application development.
