ios - Correct usage of NMSSH -

when session created, shell started , commands written: no responses recieved , callback methods buffer never called, did miss?:

(executing single command using channel:execute works)

  -(void) createsessionwithadress:(nsstring*)address username:(nsstring*)user   password:(nsstring*)pass{       session = [nmsshsession connecttohost:address withusername:user];       if (session.isconnected) {         [session authenticatebypassword:pass];       if (session.isauthorized) {           nserror *err = nil;           session.channel.delegate = self;           //self.receiveview.text = [session.channel execute:@"ls" error:&err]; // works            [session.channel startshell:&err];           nslog(@"authentication succeeded");        }     } }     - (void)channel:(nmsshchannel *)channel didreaddata:(nsstring *)message{     nslog(@"read data!");     receiveview.text = [nsstring stringwithformat:@"%@   \n%@",receiveview.text,message]; }  - (void)channel:(nmsshchannel *)channel didreaderror:(nsstring *)error{     receiveview.text = [nsstring stringwithformat:@"%@    \n%@",receiveview.text,error]; }  - (bool)textfieldshouldreturn:(uitextfield *)textfield{     nslog(@"return pressed");     nserror* err = nil;      bool commandsucess = [session.channel write:sendview.text error:&err];     [session.channel write:@"/n" error:&err];      if (commandsucess) {         nslog(@"command written successfully");     }else{         nslog(@"command not written successfully");     }      return yes; } 

pty mode needs enabled, , there som issues in library (should fixed now)
