I'm observing a property of one of my classes, "selectedIndex". Even if the
value is set to the same value, KVO fires and my observe method gets called,
which is something I thought by default it doesn't do.
So I implemented a custom setter for my property, like this:
- (void)
setSelectedIndex: (NSUInteger) inIndex
{
if (mSelectedIndex == inIndex)
{
return;
}
[self willChangeValueForKey: @"selectedIndex"];
mSelectedIndex = inIndex;
[self didChangeValueForKey: @"selectedIndex"];
}
Sure enough, my method returns early, but KVO still gets called. What am I
misunderstanding?
Thanks,
Rick
