I would like to use the new External Binary Data for Core Data that came with iOS 5. I have had a look at articles about it such as: http://bluecrowbar.com/blog/2011/08/coredata-external.html
None of them actually show how to enable it other than telling you to check the box for "allow external storage".
I have an entity set up with some of its attributes as binary data but I can't find the checkbox anywhere. Could someone please explain where I can find it? Thanks
