NSJSONSerialization - What is the proper value to specify no NSJSONWritingOptions for dataWithJSONObject:options:error:?

Question

Apple's documentation has the NSJSONWritingOptions enum with one constant defined: NSJSONWritingPrettyPrinted, and says that "If this option is not set, the most compact possible JSON representation is generated."

I definitely want the most compact JSON representation.

My question is: what is the proper value to pass the dataWithJSONObject:options:error: function if I don't want pretty printed, and why?

The NSJSONWritingOptions enum is defined as

enum {     NSJSONWritingPrettyPrinted = (1UL << 0) }; typedef NSUInteger NSJSONWritingOptions;

I have read in a different post that 0 should be passed, but with no further explanation as to why it shouldn't be nil.

Answer 1

It can't be nil because it's an NSUInteger. So, you should pass 0, which represents that the option is not set.
