How to add strings [duplicate]

Question

Possible Duplicate:
How do I concatenate strings in Objective-C?

I have two strings and wish to make a third string which combines the two by concatenating them.

NSString *a = a; NSString *b = b; NSString *c = a+b;

The problem is that Xcode does`t let me do a+b, so I don't know how to add strings. I've also tried this:

NSStirng *c = @"%@%@",a,b;

But it doesn't work too. Please help me with this noob question!

Thank you!

NSString *c = [NSString stringWithFormat:"%@%@", a, b]

or

NSString *c = [a stringByAppendingString:b];

The latter being slightly more efficient.

Try

NSString *c = [a stringByAppendingString: b];
