Try with below modified code

     int y=0;
     NSMutableArray *languageArray=[[NSMutableArray alloc]initWithObjects:@"Chinese",@"Spanish",@"English",@"Arabic",@"Hindi",@"Bengali",@"Portuguese",@"Russian",@"Japanese",@"German",nil]; 


                    for(int i=0;i<[languageArray count];i++)
                    {
                      UILabel *languageLabel=[[UILabel alloc]initWithFrame:CGRectMake(0, y ,90,30 )];
                        NSLog(@"array count is @%d",[languageArray count]);
                        languageLabel.text=[languageArray objectAtIndex:i];
                        NSLog(@"array objectat index is @%@",[languageArray objectAtIndex:i]);
                        languageLabel.font=[UIFont systemFontOfSize:19.0];
                        languageLabel.backgroundColor=[UIColor clearColor];
                        [languageScrollView addSubview:languageLabel];
                    //  [languageScrollView addSubview:languageLabel];
                        //y+=90;        
                        y+=languageLabel.frame.size.height;
                        [languageLabel release];

                    }
