In Xcode while releasing the object in dealloc method by like [self.object release] this line is shown as memory leak using static code analyzer but it not showing as leak while running instruments.
Here my question is what is the different BWN [self.object release]
and just [object release]
Please clarify this,
Thanks in advance.
self.object
actually calls the getter method ( [self object]
), which returns the instance variable object
(or depending how is synthesized), but the instance variable actually holds the retained object, so you must do [object release]
. It's good practice to synthesize your properties with: @synthesize object = _object
so you don't get confused of the property and the instance variable - your property will be self.object
, but the instance variable will be _object
and you will call [_object release];
instead of doing -
[self.object release]
you need to do -
self.object = nil; or [object release];
[self.object release] will send the release call to the object returned by getter of property. And result will depend whether the property is defined as assign / copy / retain.
