Add one string to another

[BuzzT]

I wanted to ask how to add one string to another one and set it as a new string.
Like:
NSString *newString = [String1 + String2]

stringByAppendingString is what you want for that:

aString = [string1 stringByAppendingString:string2];

And how to do it if i have 3 or more strings?

NSString *newString = [NSString stringWithFormat:@"%@%@%@%@%@", string1, string2, string3, string4, string5];

grr Brian beat me to it - i knew the answer to that one as well!! lol

[ngaikwad]

NSString *newString = [NSString stringWithFormat:@"%@%@%@%@%@", string1, string2, string3, string4, string5];

or
a =a+b
nsstring a=[a stringbyappendingstring:b];
