Yes. The problem you are facing has nothing to do with libssh2. The
part of your program that *is* related to libssh2 is already working
correctly for you.

"The UITextView class implements the behavior for a scrollable,
multiline text region."
UITextView is completely useless as a terminal emulator.

The first hit on google.com is:
http://www.chiark.greenend.org.uk/~sgtatham/putty/
PuTTY: A Free Telnet/SSH Client
Surely you saw that? Study the source code. Learn about terminal
emulators. Also search for information about terminal emulators of
course, and study the material that you find.
Again, the first hit on google.com is:
http://en.wikipedia.org/wiki/Terminal_emulator
If you have problems even finding this quite basic information then
I would caution against continuing this project now. Terminal
emulators will cause you much more trouble.

I don't.

In the function call you tell the server that you are xterm.
(xterm is one specific terminal program.)
Now the server will use the escape sequences that xterm understands.
In order to display the screen correctly you must interpret them in
your program. This is what a terminal emulator does. You can look at
the xterm source code, but xterm is very full featured and the code
is rather large, so it is not the best reference for a minimal
terminal emulator.
It seems that someone is already working on what you need. The very
first hit on google.com when searching for iphone terminal emulator
is:
http://code.google.com/p/mobileterminal/
mobileterminal
A GUI Terminal application for the iPhone
Integrate this with libssh2 correctly and you might be finished
already.
