How to combine NSString objects

- by

Say you had two NSString objects, firstString and secondString and you’d like to combine them into a new string called comboString. You can use the convenience method stringWithFormat for this:

NSString *comboString = [[NSString alloc]initWithFormat:@"First %@ and second %@", firstString, secondString];

Any variable is passed at the end of the string, replacing each %@ symbol.
