swift - CALayer, CAConstraint & Disabling the Animation -

-

i wondering if there's way disable animations particular layer?

my example here bog standard calayer (the nsview's calayer), , sublayer, catextlayer...

catextlayer nicely tethered nsview's calayer , should.. no issues there...

how turn off "easing" animations when view resized?

literally have in nsview subclass:

    override func awakefromnib() {         var newlayer: calayer = calayer()         newlayer.backgroundcolor = nscolor.blackcolor().cgcolor         newlayer.layoutmanager = caconstraintlayoutmanager.layoutmanager()          self.layer = newlayer         self.wantslayer = true          var textlayer: catextlayer = catextlayer()         newlayer.insertsublayer(textlayer, atindex: 0)         textlayer.string = "yay layer"         textlayer.foregroundcolor = nscolor.whitecolor().cgcolor         textlayer.name = "textlayer"         textlayer.fontsize = 42.0;         textlayer.alignmentmode = kcaalignmentcenter;         textlayer.addconstraint(caconstraint(attribute: .midx, relativeto: "superlayer", attribute: .midx, scale: 1.0, offset: 0.0))          textlayer.addconstraint(caconstraint(attribute: .maxy, relativeto: "superlayer", attribute: .maxy, scale: 1.0, offset: -50.0))      }

here's clip of i'm getting:

screen capture of wobbly (eased) constraints

what expected textlayer adhere constraints until otherwise given animator..

is there way stop, remove, or otherwise stop it?

cheers,

a

textlayer.actions = ["position" : nsnull()]
