This is my build documentation for an ASUS Z170-A setup with an NVIDIA GTX960 and the Intel i5 6500, most of this came from Storks asus rog maximus build, his audio instructions didn't work for me so it differs substantially there. This build also doesn't have NVRAM. Nearest I can tell everything is running as expected, including all USB and audio ports.
When you have two objects A and B, say two view controllers, that you want to have talk to each other, you can choose from the following options:
NSNotificationCenter. This is anonymous one-to-many communication. Object A posts a notification to the NSNotificationCenter, which then distributes it to any other objects listening for that notification, including Object B. A and B do not have to know anything about each other, so this is a very loose coupling. Maybe a little too loose...
KVO (Key-Value Observing). One object observes the properties of another. This is a very tight coupling, because Object B is now peeking directly into Object A. The advantage of KVO is that Object A doesn't have to be aware of this at all, and therefore does not need to send out any notifications -- the KVO mechanism takes care of this behind the scenes.
Direct pointers. Object A has a pointer to Object B and directly sends it messages when something of interest h
