Is it correct to write [self.someproperty release]

When i implement dealloc method i used to write:

[preopertyX release];

Tod开发者_开发问答ay i found this code:

[self.propertyX release];

I'm not sure that this method is completely correct. What do you think about ? (we can take as assumption that propertyX is a retained and synthesized property).

From my understanding, you should either set it to nil or you can release the instance variable.

[self setPropertyX:nil]

or

[propertyX release]

The method you list can have unwanted side effects, but if you want the side actions of your setter to happen, I suggest setting to nil.

The accepted answer here: iPhone - dealloc - Release vs. nil is pretty good.

This is a nice debate outlining, pretty vibrantly, the methods available to you.

You can write [self.propertyX release] if you have set propertyX retained and synthesized otherwise not
