Print Statement in Objective-C

Question

I've just started on xcode today, so please excuse the total noob question here.

My code is:

NSString *name = @"";
int age = 0;

NSLog(@"What is your name?");
scanf("%s", &name);
NSLog(@"How old are you?");
scanf("%d", &age);


NSLog(@"Your name is %@ and you are %d", name, age);

And the output I get is:

Your name is 2001-01-01 00:00:00 +0000 and you are 29

As you can see, the string is not printing as expected. Please help???

Thank you in advance!

If scanf did work for NSString (which it does not) you'd use `%@`, not `%s`. — Hot Licks, Mar 03 '14 at 03:22

Scanf doesn't work with objects. Here's a SO answer that shows how to read data and put it into a string.

scanf does not work with any object types. If you have a C string and want to create an NSString from it, use -[NSString initWithBytes:length:encoding:].

Use

[NSString stringWithUTF8String:(const char *)];
