ios - Generating an audio file on the fly? -


i need generate on fly audio file alarm based app i'm working on. need include bell sounds @ intervals, , length of audio file depends on user input. there way this? i'm thinking of using approach around of background limitations on ios, you're allowed play audio in background. possible?

thanks

you can compose longer sounds existing samples using avfoundation, namely avmutablecomposition class. vary background audio playback should make sense given app’s purpose. playing audio keep app running in background app rejected @ review.

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).
