All suggestions here are reduced to an external file (bundle) usage. Just for a
case, if you really wish to store any data (non-executable code, like images,
etc.) within the executable (regardless of the type: the main project, a static
library, a dynamic library) there is a way to do it. But you'll need to know
how to use assembler in the Cocoa project. If you know it, this way is for you.
I used it in my Windows project, but never in Cocoa.
AFAIK, you need to create a .s file and add it to your Xcode sources. Then
Xcode will know what to do with this file. And you need to write something like
this within the .s file:
.text
.globl _MyFunc
pushl %ebx
call L1
jmp L2
.align 1
.byte 0x0,0x1,0x2,0x3,0x4
.byte 0x5,0x6,0x7,0x8,0x9
L1:
popl %eax
movl eax, ebx
pushl %eax
ret
L2:
addl 5, %ebx
movl %ebx,%eax
popl %ebx
ret
As a result, you'll have the address of the embedded information in the eax
register. I.e. you just need to create the function declaration like this one:
(void *) myFunc(void);
and call it. Hope this code is close to correct one, as I never dealt with Mac
OS assembler. And please take it into account, that "5", mentioned in the code
above, means the size of the "jmp L2" instruction, which is five in 32-bit
assembler, but it will take nine bytes in the 64-bit one. And of course, I'm
talking only about x86/64 assembler. Don't know anything about PowerPC one.
The only what is left out is how to fill out the ".byte" with a useful
information. Personally I used a specially written simple utility, transcoding
any binary file into the fixed length lines of ".byte " hex codes. You can use
decimal or octal codes too. as far as the assembler allows it.
HTH!
