    You could also try the search function. This brought up [this question][1]. [1]: http://stackoverflow.com/questions/510269/how-do-i-concatenate-strings – Thorsten Dittmar Nov 26 '12 at 17:26

Please use below code.

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

What you are talking about is concatenating. And you need to use:

NSString *a = @"This ";
NSString *b = @"is a string";
NSString *c= [NSString stringWithFormat:@"%@%@", a, b];

You can also use stringByAppendingString: like so -

NSString *completeString = [a stringByAppendingString:b];
