proper memory handling for an NSMutableArray assigned to property?

Question

I have a property declared like this:

@property (nonatomic, retain) NSMutableArray *pricingLevels;

And I assign it like this:

Answer 1

The issue is while initializing and releasing you shouldn't use self infront of the variable

self.pricingLevels = [[[NSMutableArray alloc] init];
//instead it should be

pricingLevels = [[[NSMutableArray alloc] init];

even on releasing it should be

[pricingLevels release];
pricingLevels = nil;
