How do I detect that an iOS app is running on a jailbroken phone?

Question

If I want my app to behave differently on a jailbroken iPhone, how would I go about determining this?

Answer 1

You can detect if a device is JailBroken or not by checking for the following:

• Cydia is installed
• Verify some of the system paths
• Perform a sandbox integrity check
• Perform symlink verification
• Verify whether you create and write files outside your Sandbox

There is an open source library I created from various articles and books. Try it out on GitHub!
