Hi friends,

i am building one app almost similar to contact management system...in which i have a detail view .. on pressing one of the table cells, a new view will be shown were the user can enter the new values and on pressing the save button the values will be updated in the database. On going back to the detail view the user should be able to see the updated values in the table cells.. or how can i update the values in detail view from another view...? i came to know that this can be acheived through Appdelegate objects ... but i couldnt understand wat is it or how it is done.... may be bcuz i am new to iPhone apps development... Pls can anyone explain me the process..
