ios - NSAttributedString to NSString UTF-8 -


my code like:

nsdata *data = [nskeyedarchiver archiveddatawithrootobject:[textview textstorage]]; nsstring *text = [[nsstring alloc] initwithdata:data encoding:nsasciistringencoding]; [xml appendformat:@">%@", text];

if have nsasciistringencoding string ok. when change nsasciistringencoding nsutf8stringencoding returns null.but need utf-8 because xml file i'm appending string in utf-8. way how that? thx reply.

if textview uitextview, , xml nsmutablestring, should able replace code with:

[xml appendstring: textview.text];

or if need > prefix:

[xml appendformat:@">%@", textview.text];

nsstring keep track of encodings. need worry encoding later when xml (store or send through web service). , can use xml.utf8string regular c-string in utf8 format.

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).
