How to convert a JavaScript array to a NSArray in Objective-C/iOS?

What's the best way to convert a JavaScript array (saved in an NSString) with this format:

["Hello", "World"]

in an NSArray?

Thanks

Try this! 

NSString * jsonString = @"[\"Hello\",\"World\"]";
NSError * serializationError = nil;
NSArray * array = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingAllowFragments error:&serializationError];
NSLog(@"NSArray - %@ \n error - %@", array, serializationError.localizedDescription);

Log:

NSArray - ( Hello, World ) error - (null)

As Felix suggested, a JavaScript array is actually a JSON array.

So I solved doing some JSON parsing. Thank you!

NSError *e;
NSArray* json = [NSJSONSerialization
                              JSONObjectWithData:[arrayString dataUsingEncoding:NSUTF8StringEncoding]
                              options:NSJSONReadingMutableContainers
                              error:&e];

I can't tell exactly what your input string is, but you can use NSString's componentsSeparatedByString function to split up a string into an array of substrings.
