Practical application record of Design Patterns
@ Laodong : The most popular article in 2016 was the sharing of some design patterns. At that time, discussions of various MVPs, MVCs, etc. were hot in the entire mobile development circle. It’s just that in recent years, it’s hard to see such articles again. This article is self-recommended by the author, and records the author’s process of encapsulating other third-party libraries. For students who are new to mobile development, they can learn more about design patterns and their ideas.
For the students who are new to this kind, I would like to stress again that there is no best design pattern in the world, only the most suitable design pattern for the current project. Don’t fall into the trap of patterning for pattern’s sake, and over-engineering is not an option.

Lookin Principle and 5 Development Difficulties
@Damonwong :Lookin is a software that can view and modify UI objects in iOS App. I believe many people have used it. I have been curious about the implementation principle of this software. The software author Li Kai brought the principle of implementing Lookin. and 5 development difficulties. It mainly realizes the communication mechanism before mac app and iOS app through CS architecture. At the same time, from the process of making the Lookin software, I have summarized the following experiences:
- How do iOS programmers learn to write macOS programs?
- How to transfer data between macOS and iOS?
- How to properly render expanded/collapsed images?
- How to render 3D images?
- How to speed up the refresh rate?
Interested students can read the original text for details.

Audio and video engineering example AVDemo 7, 8, 9
@JonyFang : Audio and video engineering examples AVDemo 7, 8, 9:
- iOS AVDemo 7: Video capture Demo , which implements video capture logic and renders captured video images for preview, and supports converting data into pictures and storing them in albums;
- iOS AVDemo 8: Video encoding Demo , connect the video capture and encoding modules in series, input the captured video data to the encoding module for encoding, and store it as a file;
- iOS AVDemo 9: Video encapsulation Demo , concatenate video capture, encoding and encapsulation modules, input the collected video data to the encoding module for encoding, and then input the encoded data to the MP4 encapsulation module for encapsulation and storage;
Dewu App H5 seconds to open optimization actual combat
@J_Knight_ : This article describes how Dewu technology increases the second opening rate of H5 pages from 30% to 75%. The article begins with an introduction to the background of optimization and the metrics used. Then, the specific optimization scheme is introduced, which is optimized on both the client and H5:
Client-side optimization:
- HTML preload
- HTML pre-request
- Offline Packet Technology
- Interface pre-request
- Pre-built link & link keep alive
- pre-rendering
H5 optimization:
- SSR server-side rendering
- HTML pre-rendering
- CSS bundle size optimization
- Image optimization
- Other optimizations
While introducing the scheme, the difficulties encountered and the effect of the scheme application are also given. At the end of the article, the front-end performance monitoring scheme used is also introduced.
Introducing Swift Async Algorithms
@Lianshu : I believe everyone is familiar with the async/await operator, and it is supported in many languages, such as js. The biggest significance of async/await is that it allows us to write asynchronous code with sequential structure, which is more clear and avoids callback hell. In March, the Swift maintenance team released a prototype version of the Swift Async Algorithm Package, which includes the implementation of async/await and operators specially designed to handle asynchronous series, such as Zip/CombineLast/Merge/Chain/Buffer/Debounce/Throttle . I believe that these operators are familiar to everyone. In fact, their usage is not much different from their use in processing collection types. Just using them with async/await can concurrency and powerful energy, and use concise code to describe complex asynchronous logic. Interested students can continue to pay attention to the follow-up progress of this package.
A brief introduction to iOS SIGKILL
@xiaofei86 : When the Exception Type of the crash log is SIGKILL, it means that the operating system killed our process from the upper layer. This article is based on Apple’s Understanding the Exception Types in a Crash Report and Addressing Watchdog Terminations
The translation and arrangement of the article introduces the meaning of different error codes of SIGKILL and how to locate and solve these problems.
Adding Custom Shortcuts To Xcode
@Speedboy : After Xcode removes the Command + T for opening Slow Animations in the simulator, it becomes very troublesome to open Slow Animations. This article teaches you how to set some custom shortcut keys for Xcode.
New Terminal Play: “Zero Code” Scripted Guidance
@AidenRao : The Internet industry is fast-paced, and apps are updated more and more frequently. How to let users understand product functions and complete cognitive iterations is a link that cannot be ignored in business development. This article introduces the exploration and practice of the Meituan food delivery terminal team in the field of user mental construction. Starting from the current business situation and the thinking of scripted thinking, the one-stop design of terminal plus management background, the combination of traditional CV and deep learning, greatly simplifies the access threshold of scripted guidance.
Xcode13 “disappeared” Info.plist file
@Barney : This article describes the official configuration changes for the Info.plist file in Xcode 13.
Starting from Xcode 13, new projects no longer require the use of configuration files (Info.plist, entitlements). If you need to modify the configuration of Xcode, please set it directly in the Xcode panel “target – Info – Custom iOS Target Properties” and “build settings”.
- Disappearing Info.plist file
- How to go back to the old Info.plist?
Flutter code generation technology APT and AOP applicable scenarios and comparison
@Damien : APT (Annotation Processing Tool) is an annotation processing tool, AOP (Aspect-Oriented Programming) is aspect-oriented programming, and there are similar concepts in Flutter. This article introduces these two technologies in detail from the following aspects:
- Concept Interpretation of APT & AOP
- The realization principle of APT & AOP
- APT & AOP usage scenarios
- APT & AOP Technology Comparison
Precisely locate the page sliding frame rate bottleneck and optimization reference
@Leo : Page fluency is a performance metric that greatly affects user experience. Starting from the principles and tools, this article explains how to define and analyze Caton, and then introduces how to optimize it from the perspectives of asynchronous rich text drawing, constraint layout, and view creation.
PROTOCOL & GENERIC IN SWIFT
@zvving : Swift provides concise & rich abstraction methods based on protocol-oriented design, which also brings a lot of ambiguity to the use of Protocol in complex scenarios. The design related to the recent official versions has also been discussed and improved. For example Opaque Result Types , Unlock existentials for all protocols .
This article compares how paradigms and type erasure are applied and the differences in their internal implementation from a simple example to help you deepen your understanding:
- static vs dynamic
- Compiler generated template code vs hidden types via Existential Container
Type placeholders in Swift
@anotheren : Type Placeholders were introduced in Swift 5.6 to further optimize type inference, allowing the use of _ to allow the compiler to automatically infer types, which is more friendly to complex paradigms such as CurrentValueSubject<Output, Failure> .
Build smooth and natural Flutter pages
@CrazyCoderShi : Flutter is famous for its high performance and high consistency rendering, but it is not as smooth as silk. This article is produced by the Alibaba mobile team and shares the challenges, monitoring tools, and optimization methods of Flutter’s fluency optimization. and suggestions. From the code to the use of the tool side, it is highly recommended
