iOS Download & Parsing Large JSON responses is causing CFData (store) leaks

Question

The first time a user opens my app I need to download lots of data. I get all of this data from the server in JSON form. Depending on the user, these JSON files can be anywh

Answer 1

I use the native JSON conversion functions with massive amounts of data with no memory problems.

I just use a standard NSURLConnection to download the NSData then do the following...

NSData *data = [NSURLConnection sendSynchronous...

// use NSDictionary or NSArray here
NSArray *array = [NSJSONSerialization JSONObjectWithData:data ...

Now deal with the objects.

No leaks as it's a native function. A lot quicker than third parts frameworks.
