cocoa touch - Setting a variable in objective c to be visible in another view -


i have viewcontroller filterviewcontroller.m , .h

i have stepper sets variable named value data type of int, variable value between 1 , 16.

the stepper sets value in method steppervaluechanged , in method need set 'global' variable accessed in firstviewcontroller.

how can set variable scope visible in firstviewcontroller?

i understand can use class this, unsure how. learning points.

it's not recommended use global variables in code, , if have use them means bad implementation.

you need check how both classes connected, maybe can use delegate inform value has changed, or send notification new value, example.

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).
