In Objective-C on iOS, what is the (style) difference between “self.foo” and “foo” when using synthesized getters?

by

I have personally settled on using an underscore prefix for ivars, and this kind of synthesize

@synthesize name = _name;

That way I don’t mix them up. The major issue with not using self is that this code

_name = ...

is very different from

self.name = ...

When the @property uses the retain option. The first does not retain the object, and the second calls the synthesized setter that retains.

The only time it makes a big difference is with assigning, so I tend to use self. all of the time so I make sure I do it on assigns.
