iphone - Difference between self.instanceVar = X and instanceVar = X in Obj-c

Question

For the following two lines in an obj-c class:

self.instanceVar = X
instanceVar = X 

Is the only difference that the 'self' version calls the synthesized 'setter', whereas the latter simply sets the instanceVar and doesn't go through the setter?

Thanks

Answer 1

Yes. The implication of this is that the synthesized getter will wrap additional code depending on how the property is specified - so use of assign / retain / copy along with nonatomic / atomic change the behaviour.
