About this wiki

The sum of all human knowledge about jailbroken iOS development.

What is this wiki for?

• Information regarding usage of iOS frameworks, both public and private, SpringBoard, system daemons (for hooking and hacking), and classes in applications included with the system.
• Information about third-party libraries or extensions for developers (PreferenceLoader, libactivator, etc.).
• Links to useful information and Open Source Projects.
• Anything else about development for jailbroken iOS devices. (The iPhone Wiki covers lots of other technical topics, including the details of devices, exploits, and iOS systems.)

As of the iOS 7 jailbreak release, we're working on this article: Updating extensions for iOS 7.

Getting started

New to developing for jailbroken devices? Welcome, it's fun and challenging! Hopefully you already have some experience with Objective-C. You will want to get familiar with MobileSubstrate and Theos, and study some Open Source Projects to see how existing tweaks work. See Getting Started and also take a look at Best Practices.

How to ask for help: You can ask questions in the IRC channel #iphonedev on irc.saurik.com (where a bunch of developers hang out). IRC is an old-school chat system; if you don't already know how to use it, the IRC page has details for you. There are also tags for "jailbreak" and "Cydia" on Stack Overflow, a site for programming questions in general; feel free to ask there as well.

Editing this wiki

• If you have anything at all to contribute, feel free to do so!
• An account is required to edit pages, but anyone is welcome to make an account. If you have trouble with the account creation process, please ask in #iphonedev on irc.saurik.com for help.

Some ideas for information to contribute:

• Add more projects to the list of Open Source Projects, or fill out details on that page.
• Expand Getting Started for new developers - what do they need to know before beginning? How do they set up a development environment on OS X, Windows, and Linux? What are common beginner's mistakes that they should watch out for? How to reverse-engineer parts of iOS for writing tweaks? How to debug with GDB and learn about memory management?
• Help Cycript explain why Cycript is fun - syntax highlighting, injection, auto-completion, generally exploring around.
• Make a page that documents a class or framework you're familiar with.
• If you've developed a library (or a tweak people can write addons for) that other developers can use, make a page that documents your project.
• Update Xcode with better information about how to build apps for jailbroken devices.
• Make the homepage more useful! For example, add links to good pages that are hidden/buried deep within the wiki.
• The following articles are linked from nowhere in the wiki: Special:LonelyPages - you can fix that by linking them somewhere.
• Check out the most popular pages and see if they need updating: Special:PopularPages.
• Write an article that is in demand: Special:WantedPages.
