ios - Override navigation controller back button -


i have uiviewcontroller called detailviewcontroller push homeviewcontroller.

in detailviewcontroller there container display subview a, b , c.

if tap button in navigation bar, navigation pops homeviewcontroller, expected. i'd override button if container displaying subview b, container updates show subview (and likewise, subview c goes subview b). , if we're displaying subview pop homeviewcontroller expected.

essentially, need able tap button force navigation not pop previous view. possible?

i know hide button , replace custom bar button item don't want that. want keep exact styling of native button.

Using Java 8 lambdas/transformations to combine and flatten two Maps -

i have 2 maps: map<a, collection<b>> mapab map<b, collection<c>> mapbc i transform them map<a, collection<c>> mapac , i'm wondering if there's smooth way lambdas , transformations. in particular case, collections sets, i'd solve problem collections in general. one thought had first combine 2 maps map<a, map<b, collection<c>>> , flatten it, i'm open approach. data notes: b should occur in value collection associated 1 a , , same true mapbc (a given c mapped 1 b ). result, there should 1 path given a given c , although there may a -> b mappings there no b -> c mappings , there may b -> c mappings there no corresponding a -> b mappings. these orphans don't appear in resulting mapac . for sake of comparison, here's example of purely imperative approach same problem: map<a, collection<c>> mapac = new hashmap<>(); (entry<a, collection<b>> entry...
