ios - Saving an Mutable Array into file via writeToFile - 


for(int x = 0; x < [tags count]; x++){     nsstring* tagsvalue = [[nsstring alloc] initwithformat:@"%d: %f", 1,      [[tags objectatindex:x]doublevalue]];      [[tagsvalue datausingencoding:nsutf8stringencoding] writetofile:fileatpath      atomically:no]; }

i understand writetofile replace file of give final value of array value. how approach i've been trying around head few hours i've had no luck thanks! :)

i think trying write directly array file.

  1. convert array in string format.

    nsstring *tagscompletestr = [tags componentjoinedbystring:@" "]; [tagscompletestr  writetofile:fileatpath                                         atomically:no];

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).
