Http://topic.csdn.net/t/20040621/16/3110412.html 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 design

IOS design patterns-bridging and ios design patterns -- We recommend you refer to the OBJECTIVE-C design mode for learning design patterns. When to use the Bridge Mode 1. Do not want to form a fixed binding relationship between the abstraction and its implementation (so that the implementation can be switched during runtime) 2. abstraction and its implementation

Summary of design patterns in Objective-C, and objectivec Design Patterns This article summarizes the use of the design patterns listed in Gang of Four in Objective-C from five dimensions: name, definition, when to use, UML diagram, and application in Cocoa Touch. For a specific list, see. If you have any errors or errors, you are welcome to provide comments and

Learn Design Patterns with me (ii), learn to design patterns Factory mode is very important in the design of polymorphism, and if applied properly, it can make the application more portable and the dependencies between classes more loosely, thus increasing flexibility. If the singleton mode is the responsibility of the class, then the factory pattern is the polymorphism of the class. So what is a factory c

Template design patterns are mainly derived from the life of some things are template can be followed. Give two examples of life, such as tea and coffee, and take a look.Tea has the following four steps: 1, boiled water; 2 Put the tea in the Water Cup; 3, pour boiling water; 4, add sugar.Brewed coffee also has the following four steps: 1, boil water; 2 Put the coffee in the Water Cup; 3, pour boiling water; 4, add sugar and milk.At this point, it can

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

Six principles of design patterns (5)-the six principles of design patterns Definition: 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. Personal Understanding: The primary objective of the dimit rule is inter-class decoupling and weak coupling. Only when the class is wea

That is, only one construction method is executed during the copy process.Clone vs final two pair of enemies. The object's clone is caused by a conflict with the final property within the object.

(); Ocar.excet (); }}Template method Pattern Applicable scenario One-time implementation of an invariant part of the algorithm, and the variable behavior is left to subclass to achieve. The public behavior in each subclass should be extracted and centralized into a common parent class to avoid code duplication. This is a good example of what Opdyke and Johnson described as "re-factoring to generalize." First identify the differences in the existing code and separate the differen

Introduction to design patterns, design patternsI. Introduction to design patterns Design pattern is a set of summary of code Design experiences that are repeatedly used, known to most people, classified and catalogued. The design pattern is used to make code reusable, make it easier for others to understand, and ensure code reliability. There is no doubt that the design pattern is win-win for others and t

[Breadth traversal and depth traversal] talking about algorithms, design patterns, and breadth design patterns In the evening, I was bored with writing a binary tree (graph)'s breadth and depth traversal algorithm. The algorithm itself is very simple, but how can it be universal? The code below is my design, please help me to see if there are any problems. I feel that there is a problem, that is, I don't kn

initialize, with the syntax of the Object.defineproperties or Object.defineproperty method type. It allows you to set properties such as enumerable, writable, or configurable.If you want to implement prototype mode yourself, instead of using object.create directly. You can use code like the following to achieve the above example:varVehicleprototype = {init:function(Carmodel) { This. model = Carmodel; }, Getmodel:function() {console.log (' vehicle mould is: ' + This. model); }};functionVehicle (
