3. Pass Kit
Passbook is a new application of ios6. It can be used to store coupons, movie tickets, boarding passes, and so on. Maybe the new application of passbook is not very popular, but I insist that this will be a promising direction. This is another attempt to replace physical entities with digital systems, and I have seen from passbook the sp
mode definition: defines an interface for creating objects, so that the subclass determines which class to instantiate. Factory method delays the instantiation of a class to its subclass.
The solution to the factory method model is very interesting, that is, the solution is not to solve the problem, and the solution is to do nothing.

I. Mode Overview
Perhaps the factory method pattern is the most widely used pattern in the design pattern. In the object-oriented design, object management is the core, and object creation is the first step of Object Management. Object creation is very simple. in C #, you only need to use the new operator to call the object's constructor. However, the time to create an object is very important.
First, from the perspective of object features, the types of abstract relationships, such as interface

I started to use QT, and the environment has been configured, so it won't be troublesome in the future. So the first step is to set up your work environment!
The following is the process of setting up my environment. I keep a record and try to avoid detours for later users.

To use the QT function, you must download the source code of QT. You must also use the QT compiling en
changes can be made in the future to add new classes to be created. Usually we use factory method as a standard way to create objects, and when we find that we need more flexibility, we start thinking about converting to other creation patterns.
