Oh, and this often confuses devs when dealing with KVO
dependent key trigger situations..
The reason that this is particularly troublesome is that KVO
registering dependent keys only triggers notifications on the class
that registered. So if you implement your safe initializer
+ (void)initialize
{
if (self == [MyClass class])
{
// register depending keys
}
}
subclasses won't trigger dependent notifications.
For the curious, the two bugs that were filed as a result of this
realization (on documentation, on framework)
