This may seem strange, so I will try to explain it as best I can: I want to write an application that will accept some code as an input and will produce a visual output. The input will be in Objective C and the output will be the output that this code describes. The output may be text or graphics based, it doesn't matter. What matters is that I don't know how can I make this input be handled as Objective C code and be executed by the system as such. Can anyone point me in the right direction?
