NSJSONSerialization from NSString

Question

Is it possible if I have a NSString and I want to use NSJSONSerialization? How do I do this?

Answer 1

First you will need to convert your NSString to NSData by doing the following

NSData *data = [stringData dataUsingEncoding:NSUTF8StringEncoding]; 

then simply use the JSONObjectWithData method to convert it to JSON

id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; 

Answer 2

You need to convert your NSString to NSData, at that point you can use the +[NSJSONSerialization JSONObjectWithData:options:error:] method.

NSString * jsonString = YOUR_STRING; NSData * data = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; NSError * error = nil; id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error]; if (!json) {     // handle error }
