Hi,
I would like to understand how an objective C is packed inside a binary
and I am using a decompiler
to see what is going on.
What I would like to know is what does the following structure represents
:
_objc_data:00E2679C EXPORT _OBJC_METACLASS_$_UIButton
__objc_data:00E2679C _OBJC_METACLASS_$_UIButton DCB 0 ; DATA XREF:
__text:off_14708\x18o
__objc_data:00E2679D DCB 0
__objc_data:00E2679E DCB 0
__objc_data:00E2679F DCB 0
__objc_data:00E267A0 DCB 0x24 ; $
__objc_data:00E267A1 DCB 0x44 ; D
__objc_data:00E267A2 DCB 0xE2 ; Ô
__objc_data:00E267A3 DCB 0
__objc_data:00E267A4 DCB 0
__objc_data:00E267A5 DCB 0
__objc_data:00E267A6 DCB 0
__objc_data:00E267A7 DCB 0
__objc_data:00E267A8 DCB 0
__objc_data:00E267A9 DCB 0
__objc_data:00E267AA DCB 0
__objc_data:00E267AB DCB 0
__objc_data:00E267AC DCB 0x34 ; 4
__objc_data:00E267AD DCB 0xFC ; ³
__objc_data:00E267AE DCB 0xE5 ; Õ
__objc_data:00E267AF DCB 0
For each objective-C class I can find an export like this, where can I
find definitions for the fields ?
Thanks
