Use CLGeocoder to generate address results based on a string.

This is known as forward geocoding.
You’ll get a number of placemarks returned which you can populate into your UI.

http://developer.apple.com/library/ios/#documentation/CoreLocation/Reference/CLGeocoder_class/Reference/Reference.html

Quick example here:

NSString *address = @"Big Ben";

CLGeocoder *coder = [[CLGeocoder alloc] init];
[coder geocodeAddressString:address completionHandler:^(NSArray *placemarks, NSError *error){

     //Do something with the returned placemarks
}];

You can also restrict results to a set region if specific, that’s all documented at the link above.
