Beginner iOS Development
To put it bluntly, iOS intermediate development means that you have learned the basic UI interface construction, put it on the shelves, and settled for a period of time. You feel that you are still suitable for this industry, and you are also suitable for and accept this so-called iOS development engineer industry. You can say Is an intermediate iOS developer.
This precipitation time can be completed in about 1 year of actual work.
If you think this industry is not suitable for you, please carefully consider your own situation, whether to switch to another computer language, or completely switch careers .Do
you understand the implementation
principle of AFNetworking? Do you understand the principle of SDAutolayout/Masonry, a layout library.
Can you handle the basic iOS crash reasons/cannot compile reasons/cannot be put on the shelf? Do
you have a certain work efficiency and stable work efficiency. (And It's not to say that one of the above has survived, is busy, works overtime every day, and has a bunch of bugs)
whether it can handle crashes caused by third-party libraries.
Can it be well integrated into the working environment and complete the work indicators at each stage? , without making yourself exhausted. The use of
Xcode The flexible use of
third-party libraries The use of
AFN
MJRefresh

Instructions : As a junior iOS developer, you need to have the following skills:

Intermediate iOS Development
How to judge whether it can be upgraded?
Conclusion
Application memory processing
Application push processing
Application modularization/unit testing
Application third-party integration/centralized management/stable iteration
Read powerful third-party source code/have a quick start with new third-party libraries Ability.
Ability to accept the development of various new functions (here, even if you haven't done it, you can still solve any business needs by learning: for example: Bluetooth, AR, camera, hardware interaction, etc.)
Clearly understand the data How to transfer data, how to exchange data between application and background, the process of exchanging data, results, format.
Flexible use of multi-threading.
Processing of various concurrent events/and rationality/fluency of interface Flexible use of
design patterns.
Description: as As an intermediate iOS developer, you need to have the following skills
Required skills (see the next item if you know all)
Advanced iOS Development
Application componentization/architecture layering
Data structure, operating system, computer network have their own understanding and cognition
Shell script/python/Ruby/JS at least one.
Note: As an advanced iOS developer, you need to have The following skills (I am not an advanced developer, so I can only give you advice here.)
Required skills
Detailed study route
Learning Route
Introduction
Here only some conceptual things and learning route planning are briefly explained. For the real knowledge, please start from the basic knowledge of iOS. Introduction to
Objective-C Concepts
Compilation principles Program startup principles End programs. Monitor system event Info. plist .pch App composition Open the program Execute the main function Execute the UIApplicationMain function Initialize the UIApplication (create and set the proxy object, open the event loop) grammar. (The definition here may be a bit rigorous, oral teaching is the main) Basic grammar Object . Attribute Data type Method Inheritance Frame/CGRect/CGPoint and CGSize memory (introduced for the case of MRC) ARC/MRC weak reference/strong reference Difference between Assign, retain, copy, strong import and @class Xcode use
The first is for the Xcode menu bar, I hope you can translate the English meaning of each function in each menu, which will help you to familiarize yourself with and deepen your impression of using Xcode.
Familiar with the various functions of Xcode.
UIKit controls.
Interface analysis (Download the App for learning).
Interface
adaptation Recommend interested developers here, download and analyze the top50 applications in each category in the AppStore, learn more about how big companies and popular applications develop applications, and the most popular ones , The novel way of developing the interface can be summarized, and guess how other programmers develop in large applications.
Code architecture.

The use of various tools and third parties.
In fact, the establishment of each project is roughly divided into: project framework construction, native interface construction, and third-party libraries embedded. There are many functions that use third-party libraries, Most third-party libraries exist for the purpose of rapid development and complete function implementation. Developers need to be able to select the best and best third-party libraries for use according to different business logic.
Code encapsulation
When using more third-party libraries Afterwards, developers are required to learn its development characteristics, as well as its encapsulation methods, and use them in their own projects to encapsulate their own code. Flexible use.
Complete projects.

iOS basics
Basic knowledge of iOS
How to learn iOS
Begin to dabble in more than the knowledge in the iOS field. You will learn the basic knowledge of related positions, such as front-end and back-end or server operation and maintenance, or project-related knowledge, and move closer to your own career plan. See
more open source Or the specified third-party library.
Collect and read various blogs or forums of the great gods.
Start to consider the detailed optimization, memory processing and power consumption in the project. Lay a
good foundation and learn various common grammars in OC.
Learn how to put on the shelves and put them on the shelves If you will be rejected for what reason, learn about the rules of App listing.
Learn more about the official documentation.
