What kingOfBliss said is the correct way. anyhow i will provide you some logic of the code. Try tis code

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{

for(NSString *particularEmail in arrayContainsAllEmailAddress)
    {
            NSString *firstLetter = @"";
            NSInteger stringlen=[string length];
            if(particularEmail.length >= stringlen)
            {
                firstLetter = [particularEmail substringToIndex:stringlen];
            }
            if(firstLetter.length > 0)
            {
                if([string.uppercaseString isEqualToString:firstLetter.uppercaseString])
                    {
                        [tableArray addObject:particularEmail];
                        //tableArray is the array which u will load into the tableview. This contains the emails that matches your search name.
                    }       
            }
    }
    // Add your tableArray into UITableView
}

Do as follows, 1)store the emails 2)When the user starts type the text in textField search the stored valu and display the values in UITableView

You should use the following delegate of UITextField

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
