ios - Handle loading of content then go to different scenes -


i have 2 scenes user can enter information (one scanning barcode, other enter number manually)

from there, want download information backend.

depending on back, want go 1 or scene.

here sample of storyboard: storyboard

i don't know how handle loading part. first idea have scene spinner , download content here. once can choose scene want go , it's done. but...

when user clicks "back" button scenes on right, goes "loading" scene instead of last "logical" scene (the input scene).

so question two-fold:

  • do handle download correctly, using scene that?
  • if right, how go last input scene instead of going loading scene? (i found solutions unwind segue, none use navigation controller, want use)

thanks

using scene loading sounds good.

as you're working in uinavigationcontroller stack here, when you're ready trigger segue next screen should pop loading view controller stack without animation, trigger segue:

[self.navigationcontroller popviewcontrolleranimated:no];  // trigger segue

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
