Question

Namaste! How often do you, experienced guys using generic pointers in daily routine and what’s the common purpose for generic pointers in cocoa-touch development?

EDIT

A variable declared as a pointer to void is a generic pointer.

There’s such thing. It may be set to an address of any variable type. I just want to know how the people use this kind of pointers in real life coding.

P.S Thank you for down voting.

Answer 1

There are fewer and fewer cases where void* is appropriate in ObjC. They’re still used for some things like context pointers for KVO, but with the addition of ARC they’re a pain to use even for that. Basically, if you need to ask when you would use a void*, you probably shouldn’t use a void*. They’re a little more common in the callbacks of Core frameworks, again usually for context pointers.

But to the question, “How often do you… [use void*] … in daily routine,” the answer is “very seldom, and as little as possible.”
