i am interested in how to develop Apps and Programs for Jailbroken Devices or Cydia, what API's do i have to involve in Xcode? Could please somebody help me with that?
thanks
Applications distributed in Cydia are developed using the same process as those in the AppStore, only they are not subject to its restrictions. You can export IPAs via Xcode without code-signing them.
If you are talking about making tweaks that modify the behavior of stock iOS apps (such as Safari or the Springboard) you need to get more information about mobile substrate and theos
Do not hesitate if you need further information
