## What it is
A Chinese-language tutorial series with demo code explaining how to adapt iOS apps to iOS 9 changes, most notably App Transport Security (ATS) and the shift to HTTPS. It is a collection of articles and Objective-C demo projects rather than a reusable library.

## Use cases
- adapt an iOS app to iOS 9 ATS requirements
- migrate an app from HTTP to HTTPS
- understand SSL/TLS requirements on iOS
- learn what changed in iOS 9 for developers
- fix networking failures after upgrading to iOS 9

## When to choose
- you maintain a legacy Objective-C/Swift app that must support iOS 9
- you need a step-by-step Chinese-language explanation of ATS and HTTPS migration

## When to avoid
- you target only modern iOS versions where ATS is already standard
- you need a maintained library or up-to-date guidance for recent iOS releases
- you cannot read Chinese

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: developer-tools, documentation, security
- domain: mobile-development, apple-ecosystem, tutorials, developer-tools
- platform: -
