Question

I’m just creating a simple program that gets user input then prints it back in the terminal. I don’t know how to get the user input as an NSString. I’ve read about scanf() in C but that doesn’t seem to be able to take strings. I was wondering if there is a possible way to do it?

Answer 1

printf("Enter your string: ");
scanf("%s", str);                    // read and format into the str buffer
printf("Your string is %s\n", str);    // print buffer

// you can create an NS foundation NSString object from the str buffer
NSString *lastName = [NSString stringWithUTF8String:str];

// %@ calls description o object - in NSString case, prints the string
NSLog(@"lastName=%@", lastName);
