cocoa - Objective-C properties -

i wondering, when accessing properties within class, have [self someproperty] or self.someproperty? or safe refer someproperty?

edit: given name of property doesn't conflict/shawdow....

[self someproperty] or self.someproperty? or can safe refer someproperty?

any 1 fine. prefer not use self when being in scope of class.

somevalue = 10 ; [ self somevalue ] = 20 ; self.somevalue = 30 ; 

all above 3 statements going modify interface variable somevalue.
