iOS development and Design Patterns-MVC Recently in the study of GOF design model This book, a cursory glance over, is really a good book. Good books should be read well, so it is necessary to understand the design patter

The design pattern is a set of ideas. However, I am a person engaged in coding. Sometimes I often think that we should consider how to implement the Code with application functions more skillfully. With the help of my masters and colleagues, I have done some work over the past few years. NET project, I love the C # language, so I found that C # has many special features when implementing some design

evolve into large applications, so there is no reason not to build on such solid coding practices. Now that you understand the design patterns and their usefulness, let's look at the five common patterns of PHP5. Factory mode Originally in design pattern book, many

instead of implementing classes when calling the lower layer. Once the lower layer changes significantly, the upper layer will not fluctuate much.Assume that the following scenarios are met: Students Public class student {public void read (honglou) {// traverse each row for (line: honglou. getlines) {// a line of James reads this. see (line) ;}} public class honglou {public list At this time, James depends on a specific class of honglou. Once Xiaoming wants to read other books (using other imp

when the error was pointed out. I will immediately say," come on here. Please wait for a notification. "Khan, so, what is an algorithm? reference a sentence in the book: An algorithm is the soul of a program.Specifically, the algorithm emphasizes details, and the design model emphasizes the overall design framework. For example, the

In recent projects, data Access objects, templates, and command patterns have been used. The feeling has a good effect on the improvement of the structure. The IF branch structure of the controller is improved with the command mode, and the action code is simplified to two lines. One problem is that the controller is not able to do unit tests and has to simplify the code as much as possible. Do you have any good experience? Recommend a good

Now you have a perceptual knowledge of "What is a design pattern". Some people may ask: "Why do you want to learn design patterns ?" There are many reasons, some are very obvious, and others are not so obvious. The most common reason for learning models is that we can use them: ● Reuse solutions-by reusing well-known designs, I can take advantage of solving pro

A small software has been restructured several times recently and is becoming more and more streamlined, but it still cannot meet its own requirements. After analysis, there is no design process and you can do it as you think of it. I have read the "big talk design mode" before, but I can still understand it when I look at it. It is hard to understand it later, mainly because I have no experience and I have

is often elusive. Often you will find that the factory method is clearly used, when the new requirements come, slightly modified, adding a new method, because the products in the class constitute a different hierarchical structure of the product family, it becomes an abstract Factory mode, and for the abstract factory model, when the reduction of a method of the provided products no longer constitute the product family, It evolved into a factory method model. Therefore, when using the factory m

introduces the mediator pattern (mediator), which encapsulates a series of object interactions with a mediation object. The mediator makes the objects not need to explicitly reference each other, so that they are loosely coupled, and can independently change the interaction between them.

ObjectiveRecently read the book "JavaScript design Mode". There is a lot of knowledge in the book, which can not be digested in a moment. Write it down first.PS: Another part of the content of Uncle Tom Blog in-depth understanding of the JavaScript seriesConstructor (Constructor) modeThe object constructor is used to create objects of a specific type-prepare obje

assigning a value to a class variable, the type of the variable can either use the class itself, or it can use the superclass of the class. It is as if we were describing a sparrow or a magpie in the sky, usually saying "a sparrow is flying" or "a magpie is flying". But if you want to ignore their specific type, then you can say "a bird is flying."Similarly, when Duck objects and object Chicken types are hidden behind super-types Animal , Duck objects and Chicken objects can be exchanged for us

I recently encountered a lot of problems in the project process, and the customer constantly raised new requirements. It was really crazy to have a full-body pull. Now, let's look back and summarize our efforts to reduce the coupling between modules and embody the "High Cohesion and low coupling" principle. Here we will introduce the six design principles of the design model, the six principles are derived

I think it is very helpful to learn about the design patterns in this book. It is easy to understand and give us some misunderstandings in a timely manner, the right example makes it easy to learn. Below are some of my own learning comments. I. What is a design pattern: We generally define a

If you are involved in java-related development, it is inevitable to use abstraction and encapsulation, which is a feature of java, but also every developer must master, Java is so, and so is Android. And the design pattern is to tell us how to write efficient and more applicable and extensibility of the code, recently also learned a few kinds of more commonly used desi
