The 'foo' in 'self.foo' is a property. The 'foo' in 'just foo' is
*not* a property, but an instance variable. It's really important
to know that the two are entirely different things, even when they
are named the same. Whether the property foo even uses an instance
variable foo is an implementation detail of your class. A property
*may* be implemented using an instance variable for its storage
requirements, and the instance variable *may* have the same name as
the property, but neither of those things are requirements.
I have trouble understanding the above. How can a property be
implemented, if not by using an instance variable?
If you're a Java programmer, it might help to think of the objective C
property like this:
bar = self.foo; // is equivalent to bar = this.getFoo();
self.foo = bar; // is equivalent to this.setFoo(bar);
Incidentally, the syntactic equivalent of Java's 'this.foo' is
probably Objective-C's 'self->foo',
Yes.
