How do I embed code in an iOS process

Question

Question:

Looking at: https://github.com/Flipboard/FLEX I see a screenshot of the frame used on the Apple Springboard, with an inscription that says:

The code insert is left as an exercise for the reader. 😇

I'm not interested in introducing it into Springboard, but if I wanted to embed the environment in another process (for example, the Calculator application), how would I do it?

As a side note, I am ready to jailbreak my device if this is the only way to do something like this.

What I tried:

• I tried to use: https://github.com/DyCI/dyci-main to enter applications to which I had a source, but I could not launch it on my device, and I also could not launch it in applications in which I did not have a source for
• I also tried using: https://github.com/johnno1962/injectionforxcode , but I kept getting initialization errors during the injection process.

I Tweeted to Ryan Olson (according to Git Guilty Magazine he posted the image) and received this answer: https://twitter.com/ryanolsonk/status/580011917491601408

It seems that this requires a jailbreak.

After doing more research, I found a tool called "Cycript" by Jay Freeman (Saurik). If you are interested in remote injection in a real application, see: http://resources.infosecinstitute.com/ios-application-security-part-1-setting-up-a-mobile-pentesting-platform/

If you are new to MobileSubstrate and Theos, you should definitely take a look: http://iphonedevwiki.net/index.php/Theos/Setup
