Setting an object nil versus release+realloc

Question

This is not a garbage collected environment

I have a class instance variable which at some point in my runtime, I need to re-initialize with a different data set than it

Answer 1

If you were on Mac OS, not iPhone OS I would say that it depends on whether the garbage collector is activated or not:

• with GC: use myArr = nil;
• without GC: use [myArr release];

Unfortunately, on iPhone, there is no garbage collection, so if you don't want memory leaks, you have to release your object once you no longer need it.
