How can I print "\n" using NSLog?

Question

How can I print "\n" to the console by using NSLog or printf function?

Basically I was trying to print a String with value "Hello\nWorld". My requirement is, I want to print it AS IT IS. But when I tried to print, it was printing like,

Hello
World   

not as

Hello\nWorld

Answer 1

Escape it using another backslash.

NSLog(@"Hello\\nWorld");

Answer 2

Try "Hello\\nWorld". If you want a literal \ in a string you need to escape it with another \ .

Answer 3

I use C strings (except in the very rare case where I'm debugging something specific to Unicode):

NSLog( [ NSString stringWithFormat:@"%s", "Hello\nWorld" ] );

Make the above into a macro taking C parameters, and it becomes portable between C and Obj C.
