Developing full C.R.U.D. app on a remote database. My app is working correctly as of publishing this question. However I would like to advance it. I am a newbie to IOS development. As you can see from my code I am getting the valueForKey name and displaying it in the tableview. Clicking on the name brings you to screen with the name in a text field. However I want to get the valueForKey for the following keys: namesid, address1, address2,address3,address4, email, mobile,telephone and comment and display them as for the name all values will be displayed in their own text fields.
