Introduction: the online criticism of MFC is endless. It is not good to say that it is similar to MFC. Some netizens even use "bad" to describe MFC. I have been learning mf c for some time. I feel that my level of MFC is moderate, and there is still a gap between my skills in using it. I have a deep understanding of the "pain" of learning MFC, so I usually try to avoid using MFC at work. A few days ago, I saw a discussion about the

Because [GOF95] is the first of a book on software patterns and is one of the most popular books in oo design theory, some people often use the term design pattern to refer to any type of schema, design, or program implementati

An object should have a minimum understanding of other objects. The dimit rule is also known as the minimum Knowledge rule. It is called the Least Knowledge Principle (LKP) in English.

High-level modules should not depend on low-level modules. Both of them should depend on abstract interfaces. Abstract interfaces should not depend on specific implementations. The specific implementation dep
Design Patterns (3) -- Abstract Factory patterns (Absrtact Factory Pattern), absrtactpattern
Definition
The essence of the abstract factory mode is to provide interfaces to create a series of related or independent objects without specifying the specific classes of these objects.
Understanding
In software systems, there are often "a series of mutually dependen
So far, I have finished learning several design patterns of the created model. Let's take a look at them.
It takes a short time. It is better to create a model that is relatively simple and will not be so smooth in the future. since there is no real practice in the project, so far, I think I have not mastered it, just a little understanding of the design model.

Basic concepts of Singleton Design Patterns in IOS when Singleton mode is used, basic steps for creating Singleton mode in a non-ARC
There are three types of design patterns: creation, structure, and behavior. Among them, the creation type is: 1. Singleton. Singleton mode: ensure that a class has only one instance, and provide a global access point to it. 2. Abstract Factory, Abstract Factory: provides an interface for creating a series of related or mutually dependent objects without specifying their specific classes. 3. Factory Method:

If you add any additional action methods, simply inherit the action method parent class, create a new action subclass, and add an else if to the simple factory class.AdvantagesThe simple factory method eliminates the coupling of the application-speci
Today in Terrylee Cnblog (http://terrylee.cnblogs.com) saw the design patterns related to the whole set of articles, beginners design patterns after reading each article to do some notes and excerpts. What is design mode and what is architecture?
? In fact, you don't have to worry about where to put it. The dimit rule gives us a solution:
If a method is put in this class, that is, the relationship between classes is not added, and there is no negative impact on this class, it is placed in the class.
4. Attention to the dimit rule (iii) -- use serialization with caution
Serialization is used to sequence object memory data so that it can be transmitted through different media. However, if our software

Adoption of design patterns in ANDROID-behavior patterns 1 responsibility chain model
The purpose of the responsibility chain mode is to allow multiple objects to process requests, so as to avoid coupling between request senders and receivers. Connect these objects into a chain and pass the request along the chain until an object processes it. So that multiple objects have the opportunity to process the re
