swift - Hierarchical Nav just to Main Controller in Apple WatchKit 2 -

-

i building app moves between set of controllers using:

self.pushcontrollerwithname("scene a", context: nil)

calling create ability @ top ideal e.g. main scene -> scene -> scene b -> scene c, how can pop whole stack main scene scene c in "pop beginning" type call? function can see goes backwards 1 step.

self.popcontroller()

there 

self.poptorootcontroller()

discussion use method return interface initial configuration. might can reset navigation hierarchy initial state before pushing 1 or more different interface controllers onto navigation stack.

always call method watchkit extension’s main thread.

availability available in ios 8.2 , later.

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
