Get view controller current scale

I've been using the .transform method of the UIViewController.view property to scaleX and scaleY my view controller.

I've been digging and couldn't find how can I check the current scale state of the VC.

I'm scaling it with:

ViewController.view.transform = CGAffineTransform.identity.scaledBy(x: 1.5, y: 1.5);

Is there any get-property like:

let currentScale = ViewController.scale ?

OR

let scaleX = ViewController.scale.x

Thanks :D

Solution

  • Try this;

    CGFloat xScale = self.view.transform.a;
CGFloat yScale = self.view.transform.d;

    After applying a scale transform, a transformation will be available through the transform property (CGAffineTransform values) on UIView.
