Why NSString Objective C

NSStrings is a class that deals with strings in objective c programming language. You can define the NSString class as given below..

NSString *mString;

and to initialize the NSString object, we use @"?." notation.

mString = @"hello world";

You can also compare a string using the "isEqualToString". for example

comparing strings in objective c

if([statusString isEqualToString:@"mString"]){
    //doSomething;
}

You can also use the separate line tag "\n" to separate the strings. For example..

NSString *mString = @"This is line 1\n"
               "This is line 2";

In the last see the code to append the strings in NSString class method.

[NSString stringWithFormat:@"%@%@%@", str1, str2, str3];
