创建会话时，会启动一个 shell 并写入命令：没有收到任何响应，并且永远不会调用缓冲区的回调方法，我错过了什么？：
（使用通道执行单个命令：执行有效）
-(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;
}
