Is it possible to include a quotation mark as part of an nsstring?

Sure, you just need to escape the quotation mark.

NSString *someString = @"This is a quotation mark: \"";
NSLog(@"%@", someString );

Output:

This is a quotation mark: "

You can use Double Quote Escape Sequence here. You need to escape it using a backslash :

NSString *str = @"Hello \"World\"";
NSLog(@"Output : %@",str);

Output : Hello "World"

There are some other Escape Sequences also. Take a look at it :

\b    Backspace
\f    Form Feed
\n    Newline
\t    Horizontal Tab
\v    Vertical Tab
\\    Backslash
\’    Single Quote
\”    Double Quote
\?    Question Mark
