Are you ready for IOS development ?, Getting started with ios development

The most common knowledge about IOS is the IOS system exclusive to Apple mobile phones. It can also be said to be a single task manager. This can be said to be an advantage. However, as the technology improves, IOS will gradually become more advanced, however, many large companies still need development talents in this field. Today we will talk about the knowledge and skills required to get started with IOS development, if you want to become a high-paying technical talent, you have to work hard.

Basic CS knowledge

In fact, we have always been misled by a concept. A high degree of education does not mean that your skills will be better than the average person, but it is important in terms of experience. Because you are not familiar with the data and structure, you may encounter errors during the development process. Therefore, it is best for beginners to first learn more about the CS script, read more books about CS so that you can grow up. This is also the easiest course for beginners to understand.

Ii. Swift or Objective-C

There are two languages: swift, and swift. You must choose one of the more traditional object-C frameworks to write code, if you want to learn more about your online search, it is not accidental for me to open an Safari page to view Apple documents during most of my work hours, in order to better write classes, struct, loops, function allocation variables, and expression evaluation levels. I suggest you study this code course more.

Technical personnel must have their most proficient language for development, whether it is object-C or swif. If there are many projects, swift can be used, and others generally use object-C, both are programming languages for developing apple platform software, and swift has only recently emerged. The compiler will eventually translate it into C language, that is to say, the compiler is actually facing C language code.

Three frameworks and APIs

It is similar to what I have said before. I don't think you must be able to back up all iosapis, but you need to clearly know where to find them.

UIKit (UITableView, UIButton, UINavigationController, gesturerecognizers)

Interface Builder (storyboards, Segues, and strange. Xib)

Basic Types (NSArray, NSDictionary, NSString) and their rapid correspondence (array, string dictionary, and) HTTPAPI (NSURLSession, basic RESTAPI concept, JSON parsing using nsjsonserializatioN)

GrandCentralDispatch (GCD, NSOperationQueue)

Data persistence (nscoding, nsuserdefaults, CoreData)

Memory Management (what is circular reference and the basic principle of arc)

4. Design Patterns in development

If you want to make your development easier, you need to pay attention to your design model, especially in IOS, the design framework is often widely used. This saves you a lot of effort, your code will be clearer and you will make a lot of different things without feeling it, and you can still learn and use it.

Proxy mode (the main mode of most iOSAPI, you must understand it)

The so-called proxy is more like a portal. Because it is mainly used to transmit data between different viewcontrollers. Suppose there are two options: MVC separation and secondVC. If you spend time improving your code ., A value entered by the user in MVC should be used in firstVC

5. Familiar with Development Environment

IOS development requires a Mac, while Android can use windows. You need to familiarize yourself with its development environment, if you are not proficient, even if you have a Mac, it is difficult for you to write the code. It is best to start with standard or low configuration.

Vi. UX/UI

Interaction design should be the designer's forum, but the most interactive interface interaction is the interaction between users and people. If your product architecture and line diagram are involved, therefore, we need to understand the principle of line diagram to facilitate future development.

There are many IOS development tools, but the following are more commonly used and I recommend your tools. Let me briefly introduce their features!

1. Xcode has a unified user interface design. coding, testing, and debugging are all completed in a simple window. It is the quickest way to develop OSX and iOS applications.

2. Git version control helps you track, branch, merge, and manage code versions.

3. JIRA or Bugzilla is basically JIRA, and you do not need to be an expert to use it, but you should at least give it a rough idea. Do not be afraid when you first see its interface.

4. CocoaPods is a tool that helps us manage third-party dependent libraries. It solves the dependency between libraries, downloads the source code of the library, and creates an Xcode workspace to connect these third-party libraries with our projects for our development and use.

7. insights

Swift can be said to be the language that Apple wants to replace object-C, because many syntactic things can be replaced by swift. After you have a deep understanding of swift, even if someone asks you in the future, you can introduce it to others and answer "I think it's okay" is not the correct answer.

8. Working Ability

When we apply for a job in this area, many interviewers ask you to write a code to evaluate your abilities. Then we can integrate the APP into applestore for release, it also shows your project capabilities. Here I recommend you use GitHub to help you succeed.
