I have developed an iPhone application which should support iOS4 and iOS5 based iPhone/iPad.
my application leaks memory at few places which is becoming hard to debug due to the size of code. I recently read about ARC (Automatic Reference Counting), my query is
do i need to modify my source code (retain/release /alloc/dealloc) to compile with ARC.
also what all changes we need to perform using ARC?
is it advisable to shift to ARC?
will my app work on iOS4 phone if i use ARC
thanks.
This is probably not the best place to have posted this question, but I will answer because I don’t mind the question being here.

you will use the migration tool ‘Edit > Refactor > Convert to Objective-C ARC’ and hand fix anything the tool can’t figure out.
Yes.
Yes but Zeroing weak references will not.
