Removing contents of pasteboard at the app level

Question

We are trying to control out pasteboard contents for our application. I have seen the way to create a custom text field and remove the ability that way, but I'm inquiring to find if there is a way to do it at the app level.

I was trying to utilize applicationWillResignActive, applicationDidenterBackground, and applicationWillTerminate. With those I figure I can clear the pasteboard contents and then have that data safe outside the app.

My initial attempt was to emulate something I had seen from a previous solution that may no longer work.

var pb = self.pasteboard()
pb.setValue("", forPasteboardType: UIPasteboardNameGeneral)

The error here being that the AppDelegate has no member pasteboard

Is there a way to make it work in app delegate, or am I relegated to changing all the fields in the app?

There is no self.pasteboard(), but there is UIPasteboard.generalPasteboard().

Use that instead.

I've implemented this and done some testing. It seems to have worked. Thanks! – James Cockerham Jun 24 '16 at 18:58

You might have seen the previous answers where self.pasteboard() returns an instance of UIPasteboard and now in your application it is not handled. So you just try this:

let pasteBoard = UIPasteboard()
pasteBoard.setValue("", forPasteboardType: UIPasteboardNameGeneral)

Or if you want to get the pasteBoard instance in all other methods then just declare a lazy var in your appDelegate:

lazy var pasteBoard = UIPasteboard()

Then use it in any methods like below:

self.pasteBoard.setValue("", forPasteboardType: UIPasteboardNameGeneral)

The first line here threw an error, but I combined your lazy var piece with the above answer and got it working. Thanks! — James Cockerham, Jun 24 '16 at 18:59
