Question

I have a general query regarding memory management

//In .h file I defined a property
@interface AClass
{
    someClass *aProperty;
}

@property (nonatomic, retain) someClass *aProperty;

end



//In .m file I synthesized the property and also initialized the property
@implementation AClass

-(void)aMethod
{
    self.aProperty = [[someClass alloc]init];
}

My question is

For ‘aProperty’, where do I do a ‘release’ to prevent a memory leak? I understand normally for instance properties (using dot notations), we do a release in the ‘dealloc’ and ‘viewdidunload’ methods. But for this instance, do I need to release aProperty again within the method ‘aMethod’?

Answer 1

1. You must release the instance in the dealloc
2. Your property initializations leaks the memory. You do alloc+init, retain inside the property, but don’t release. Something like self.property = [[[someClass alloc] init] autorelease] is usually used.
