Objective-C: The Path to magic [1-Chapter 1]

Do not repost the labor results of developers

C language was first developed at the at&t lab,

The development of Unix OS has promoted the rapid popularization of C language. Almost all unix OS are written in C language.

Brad J. Cox designed the objective-C language in the 1980s s, based on a language called SmallTalk-80.

SmallTalk-80 can refer:

Objective-C adds a layer based on the C language, which means that C is extended,

This creates a new programming language that supports object-oriented creation and operations.

In 1994, next computer and Sun jointly released a Standard Specification for the nextstep system, called openstep.

This system serves as the basis for Apple's OS X release. The Development Environment version of this version has become cocoa by Apple.

This article mainly introduces that OS X comes from the nextstep system. The development environment is called cocoa.

When the iPhone was released in 2007, Apple initially did not welcome third-party application development. Only Web-based applications can be developed.

Finally, developers were very dissatisfied, So Apple soon announced that developers could develop so-called local applications for the iPhone.

This is what we call the native application.

IOS developers step by step into the programmer's field of view.

C language is process-oriented. It is not necessary to learn objective-C before.CompleteC language.

Objective-C is only an extension of the C language. The key is that it is object-oriented. Therefore, we need to develop a good object-oriented programming style.

"A picture is better than a thousand words, not a picture is a JB." The same is true for learning computer languages,

It is strongly recommended to run every program (one letter or one letter is required ).

Language is just a tool. However, the tool has its own set of original ideas, development environment, and application scenarios,

There is no distinction between good and bad, and the idea is worth exploring.

In this way, you can select a suitable language to achieve twice the result with half the effort.

While organizing the computer, accidentally turning to "programing in objective-c" under a "hidden" Directory ";

The first page is fascinating.

It's really "no crazy, no survival ".

A few days ago, I saw "super body", and my brain was so powerful!

So:

Wentao has a series of specialties.

There is no learning problem, only the speed and depth of learning, the skillful application and the high super individual differences.

Ancient and Modern great undertakings and university practitioners must go through three realms:

"The West Wind withered green trees last night. A tall building exclusive to the sky ." This is also the first place.

"I don't regret it when I get out of my clothes, so I am worn out ." This second stage is also true.

"Looking for him in the crowd, suddenly looking back, that person is in, the lights dim ." This third realm.

Let's embark on our own objective-C magic path...
