NSView conforms to NSCoder, which is where this initializer comes from.

Swift will take care of the latter for you, so you would just need to decode whatever information you need. Of course if your view doesn’t support any additional archiving above and beyond what NSView does, and you will never use it in a nib or storyboard, you can just leave the implementation empty. > > -- > Have a great day, > Alex Hall > mehg...@icloud.com > > _______________________________________________ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/david.duncan%40apple.com > > This email sent to david.dun...@apple.com -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
