Yes, you could do by using the StringWithFormat or initWithFormat function of NSString.

Do something like below ..

NSString* myString = [[NSString alloc] initWithFormat:@"%@ %@ %@",@"a",@"b",@"c"];

Assign myString to your label.

Neither UILabel nor the UIFont you set it to have character spacing options. There's likely a way to do with with Core Text, but a quick look through the framework documentation didn't reveal it.
