Anyone knows how to read all contacts from address book and show it in a tableview in the main screen ?
A:
That is a very general question but you should start by looking at ABAddressBook which will allow you to retrieve address book records. It is well documented by Apple.
Then you can use this data to populate a UITableView with UITableView cells representing the records. Again, both of these classes are well documented by apple and here on stack overflow.
