objective c - Passing an object between view controllers, does the object become null in new controller? -


i new objective c , trying head around oop in apps opposed web oop.

lets have class theday.h , theday.m

setday class in 1 view controller takes in value, integer, via set method, , in view controller using method can value example: (if syntax wrong sorry, new!)

[theday setday:1];

then it:

int day; day = [theday getday];

is correct , object available throughout views?

yes object available! passing reference object, not object!! have allocate object somewhere in code!

this link help!

linux - Does gcc have any options to add version info in ELF binary file? -
