Hi,
The called app is not a GUI. That's why I use NSTask.

I have one application using NSTask to call another my application,

If your other app is (or should be) a GUI app, listen to what John
wrote. NSTask is not good for GUI apps, and you shouldn't just display
a command-line app's data in a fake console window. If you do that,
your users might as well launch it from the command line themselves.
1. Printout on the NSTextView window the display strings from the
other my app(use printf) in real time not wait for to the end of the
called app. (because my app run in loop)
You have to read in background. See NSFileHandle.h
2. Get input from the user and send to my app because my app need to
get input from user to stop (i.e: "s" character).
Just send the text into the NSTask's stdin. If you don't know this, be
sure to learn about Unix pipes and Unix processes. This works the same
way on all Unixes, not just MacOS X.
BTW -- there's a really good tutorial about NSTask out on the web. I
think it was at http://www.cocoadevcentral.com, but it may also have
been at O'Reilly's MacDevCenter.
