C language is a process-oriented programming language, while OC is an object-oriented programming language. Object-oriented: For example, you do a dish, let the wife cook a dish, eat, this is the object-oriented, high efficiency oriented process, is every detail: for example, you have to take or open to the appropriate position. And then to wash vegetables, and so oil heat, to start cooking, and then seasoning,..., pot, into the bowl, eat .... Object-

OC is an object-oriented language, so it also has the concept of class, object, static \ Dynamic method, member variable. This is to create the first OC class.I. Introduction to Grammar1. ClassIn Java, we can describe a class with 1. java files, and in OC, you typically use 2 files to describe a class:1>. h: A declaration file for a class that declares a member v

The previous article briefly introduced the overview of OC. From this article, we began to learn about OC. Before learning, I personally felt that I needed to know the other two languages: one is C/C ++, and the other is an object-oriented language (of course, C ++ is object-oriented, but it is best to us

After the swift language comes out, it may be possible for new projects to be developed directly using Swift. However, you may encounter some situations in the process. Some classes or encapsulated modules that have been written in
ObjectiveBlink of an eye Swift3 come out almost a year, from OC to Swift also experienced a lot, so on the use of the difference also summed up a little, for the record, right when one of their notes.Of course, some of the differences may be heard, so here will also combine their own some of the usual records, a little finishing, just born this article, the middle may have the wrong place, also hope points out, common progress.BodyI.

OBJECTIVE-C, abbreviated as OC, is a language based entirely on the C language, adding object-oriented features to the main body of C language, and it can be said that OC is the expansion of C language. Any C language program, without modification, can be completely compiled by OC, visible, in the syntax, OC is fully c
In the development of iOS apps, Swift will replace OC, the trend is "short-term coexistence, long-term replacement." But there have been too many code in the OC language, and Swift's development has inherited a lot of features from OC, and there are a lot of similarities. Swift and OC can now be seamlessly mixed-progra

Cross-Use of swift and OC in projects
The compatibility between SWIFT and OC allows you to use swift + oC to write applications in the project, called mix and match ), in this way, you can enjoy the fast features of the new language while seamlessly joining your existing OC C
Yesterday we introduced the definition and use of classes in OC: Classes
I. First, let's take a look at the class initialization method.
In Java, we know that each class has a constructor. The initialization method here is similar to the constructor method, but the difference is that Java has a default constructor, when we customize the constructor, this default constructor will be replaced, but it will not be in

Mixing OC and Swift
Swift's development momentum is getting better and better, and it is difficult for many companies to switch from OC to swift all at once. At this time, mixed editing is so important. I am gradually trying to mix and then gradually replace OC, so that all requests are forwarded to swift.
In fact, swift began to study the syntax and definition o
Objective-c language is a dynamic language that puts a lot of static language in the process of compiling and linking things to the runtime. At the same time OC is also a simple language, a large part of the content of C, just add the language level of the keyword and grammar, really make OC powerful is its running, it is very small but very powerful, wherein the core is the message distribution.
