Question

So assume I declared an object and created a retained property for it which is synthesized. So something like that in the header file:

NSArray *array;
@property (retain)....

After it is synthesized, I called release in the dealloc.

Now in the init method, if I want to also dynamically allocate that array, what do I do in terms of releasing it? So:
array = [[NSArray alloc] initWithObjects...

How do I keep the object retained as long as the class is running without leaking?

Thank you

Answer 1

self.array = [[[NSArray alloc] initWithObjects:...] autorelease];

or

NSArray *newArray = [[NSArray alloc] initWithObjects:...];
self.array = newArray;
[newArray release];

With both options, you additionally have to call [array release]; in dealloc.

By using its setter method, you normally don’t have do worry about retains and releases.
