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

You can convert your string to NSData by saying:

NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];

You can then use it with NSJSONSerialization. Note however that NSJSONSerialization is iOS5 only, so you might be better off using a library like TouchJSON or JSONKit, both of which let you work directly with strings anyway, saving you the step of converting to NSData.
