Objective-c basic knowledge study notes, objective-c Objective-c basic knowledge study notes (1) I have always had the habit of recording notes, but I haven't shared anything for a long time. I just learned about IOS in the first half of the year. Now I have time to write. Due to the development needs, the company specially configured several new MAC for us, an

Most beginners who have a basic development experience on other platforms are eager to see xcode. After seeing the interface builder, they are eager to get started with the objective-C syntax, the first thought becomes daunting. Okay, I'm talking about myself. If you are like me, you are interested in apple-related development: Mac OS X or iPhone, but the first time you see objective-C, it will cause headac

Interoperability (interoperability) allows developers to define swift classes that incorporate the Objective-c language features. When writing the Swift class, you can inherit not only the parent class written in objective-c language, the OBJECTIVE-C protocol, but also some other features of objective-c. This means tha

Objective-C Protocols, objective-c Objective-C Protocols 1.1 Formal Protocols A formal protocol (like an informal protocol) is a named list of methods and properties. Formal protocol (like informal protocol) is a list of names of a series of methods and attributes. However, a formal protocol requires that you explicitly adopt it. Formal protocol requires you to e

Objective-C magic path [2-objective-c programming], objectivec Programming Do not repost the labor results of developers There are two main ways to compile and run the Objective-C program: 1. Xcode integrated development environment. 2. Use the Terminal command line window of the GNU Objective-C compiler. Use Xcode X

As we all know, Objective-C is more used to develop iOS and Mac applications. A newly released foreign website has moved the Objective-C language application to the cloud. It is currently in the public beta stage and has the following main features: Use Objective-C to build perfect applications on the cloud Click to create a database. Auto Scaling Your f

Objective-C (19th, notification-one of the message sending modes)-iOS development basics, objective-cios Combine the previous study notes and refer to Objective-C programming full solution (Third edition) To summarize Objective-C knowledge points. Knowledge points keep changing, just for reference,Take the official do

Let's talk about Objective-C warnings and objective-c. Address: http://onevcat.com/2013/05/talk-about-warning/ A programmer with exercises cares about the warning of his own code, just like a dead cockroach on the side of the rice bowl. -- @ OnevcatCompilation warning Now the compiler is sometimes very noisy, and the warning given by the compiler is very useful to developers. The warning will not stop comp

Codeblocks integrated objective-C Development 1. First install the objective-C Compiler Gnustep Windows Installer provides a simulated development environment for objective-C on the Windows platform. There are four software packages, including gnustep system and gnustep core, gnustep devel and Cairo backend are optional. Render manager must be installed and insta

Swift's compatibility with objective-c allows you to use both languages in the same project. You can use this feature called mix and match to develop a mixed-language application that can implement part of the app's functionality with the latest features of Swfit and seamlessly incorporate into existing objective-c code.Mix and Match OverviewObjective-c and Swift files can coexist in a project, whether the

trend of information processing technology is from a large number The transaction database extracts data and clears and converts it to a new storage format, that is, the data is Aggregation in a special format. With the development and improvement of this process, such special data that supports decision-making Storage is called Data Warehouse (DW ). W. H. Inmon defines data warehouse as a topic-oriented a

Objective-C traps and defects, objective-c traps Objective-C is a powerful and useful language, but it is also a little dangerous. This topic is inspired by an article on the C ++ trap to talk about the traps in Objective-C and Cocoa. Introduction I will use the same definition as Horstmann: traps are code that can be

Explanation of Objective-C's run loop, objective-cloop Objective-C run loop I don't know if you have ever thought about this problem. An application is put there after it starts to run. If you don't perform any operations on it, the application is just as static and will not take any spontaneous action, however, if we click a button on the interface, the corresp

Objective-C Variable Parameter Function implementation, objective-c variable1. Preface I believe that those who have been familiar with OC are familiar with NSLog. By carefully checking the original definition of NSLog, we will find that its prototype is as follows: FOUNDATION_EXPORT void NSLog(NSString *format, ...) NS_FORMAT_FUNCTION(1,2); The path is:OS X version/Frameworks/Foundation/NSObjCRuntime.h Not

Correct Method of Objective-c Singleton mode and objective-c mode The Singleton mode may be one of the most common models in iOS development, but it is relatively difficult to write a correct Singleton mode due to the language characteristics of oc, here I will talk about the design ideas of the single sample mode in iOS. For more information about the singleton mode, see this article. A Singleton, as its n

[Good programmer training camp] Objective-C learning notes --- constructor and destructor, objective-c learning notes In short, constructor initializes an object and initializes some member variables of the object, the Destructor cleans up objects after they are deleted. The code below is used to describe them. 1. Constructor In OC, all functions starting with init are called constructor. When a construc

reference count (automatic refrence Counting,arc): The system tracks the object and decides which one will still be used and which one will not be used again. Arc works at compile time, and the retain and release statements are inserted in the code. Valid range: The object pointer that can be persisted Code block pointers Objective-c pointer pointer defined by attribute((nsobject)) type Conditions that are sa
