Hi Jay,
I think copy will be your answer, but you should look at the
documentation to see how it works.
[array autorelease] //I'm not sure about this part
array = [inArray copy]; //Copy automatically retains I think, so no
need to retain
The other thing is:
[array release];
[inArray retain];
This is wrong. You always want to retain first, then release because if
array = inArray you get problems. So just reverse the order:
[inArray retain];
[array release];
array = inArray;

I have two classes MainClass and AClass
AClass has a method (with data item array)
-(void)setInfo: (NSMutableArray *)inArray
{
[array release];
[inArray retain];
array = inArray; // also tried array = [inArray
mutableCopy]
}
MainClass has an AClass defined and calls this method passing in a
mutable
array and when i debug everything is copied fine. However when later
methods and delegates are called of AClass the array it the old one
that was
defined in the initial init call. I checked init and it is only being
called once so
I am assuming that in the setInfo function I am only copying it for
the duration
of the method .... how can I get it to last more than the duration of
the setInfo
method?
any ideas are greatly appreciated
