I am new in Objective-C programming, can any one tell me how to Concatenate 2 or more NSString into 1 NSString with comma(,) sign.
For example I have 3 strings like this:
NSString *country1 = @"India";
NSString *country2 = @"China";
NSString *country3 = @"Japan";
I want to make a single string to store and in future I want to separate all these values by given sign.
