NSTask or equivalent for iPhone [closed]

Answer 1

NSTask is available in ios 4, ios 3 and possibly all of them. To use NStask I had to copy the NStask header file from my mac to my project folder. Also Apple will most likely not allow an app that uses NStask in the appstore. Cydia would probably be the best place to distribute your app

Answer 2

Just reminder:
NSTask will not work under sandbox environment (you will get "deny process-fork"). So put your application into /Applications

Answer 3

It wasn't removed in 3.0, it was never there. There is no way to run separate processes on the iPhone. GDAL appears to be under an MIT style license and has a library interface, so directly linking it into an iPhone app shouldn't have any legal or technical issues.
