That's quite normal. JSON can send null values to your app. If it does, then this is done intentionally by the server and it expects you to handle it. Figure out what the correct behaviour is when a null value is received. Then when you get an object that could be a null value, check

if (object == [NSNull null])
{
    // stuff to handle null objects
}
else
{
    // stuff to handle non-null objects
}

The real problem isn't that your app crashes, but that your app doesn't handle JSON data that it is supposed to handle.
