You’re calling it on the NSData? That’s the wrong way round. You call that 
method to ask if you can turn an in-memory data structure _into_ JSON data, not 
to see if JSON data is parseable.

In other words, the parameter to isValidJSONObject: should be an NSArray or an 
NSDictionary, otherwise it’s always going to return NO.
