I like your book and videos about iPhone programming. I have problem, I was trying your sample program DVD case. I just added the data in homeDVD (in yours only Thomas the Builder and added 4 more data), also the same in workDVD (I have added more data) and I changed in DVDCabinetController.xib at tableview attribute, the style from plain to be group and separator from single to be none. When I ran the program style was working properly and there are still single line between data. could you help me to check why this attribute option in DVDCabinetController.xib did not work properly?
