This might prove helpful. It's basically a JSON validator to check if your JSON files/code is valid. You might want to give it a go.

http://jsonlint.com/

Edit: I saw your comment. One bug - after thumbnail in your JSON string you have forgotten to put a comma. The other issue is that your content seems to have these special characters that aren't part of the traditional ascii set. I'm not sure on how to handle that

If this is the error you are getting

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary objectAtIndex:]: unrecognized selector sent to instance 0x6e07dd0'

Then you are trying to access an object using objectAtIndex: for an NSDictionary object instead of a NSArray. NSDictionary does not support objectAtIndex: Please check your response after parsing and then check the type.

If you added JSON as library, Then you need to add -all_load to the linker flags.
