How to install your dictionary in iBooks on ios8.*?

Question

iOS

Is there any way to add custom dictionary to iBooks on ios8?
On version 7, it worked through Dictionary.append, then when this feature was covered, it was possible to replace the existing dictionary with your own through the jail, on version 8 it no longer works. It is necessary that it works offline (iPad without 3g), so other readers with online translation are not suitable.

(in earlier versions of the OS it had to be edited), I made a note in detail timofey.website/dobavl promises-slovaria-v-ios-8
