the SpinerLayer isn't showing when call the method 'startLoadingAnimation()'

[dongdong3344]

With Xcode Version 8.3.3 (8E3004b), I create a loginAndRegister Button, when I click the button, I want to call the 'startLoadingAnimation()' Method, but the sipnerLayer with default configuration won't show on the button.
I didn't modify any file which in the TKSubmitTransition folder. Any analysis for it ?Thanks!

As far as I see, this line
layer.add(shrinkAnim, forKey: shrinkAnim.keyPath)
causes all the problems.

Also, there is a problem with spinner when constrains in storyboard are broken

Same problem here on iOS 10, XCode 8, Swift 3.0. Any workaround?

The problem occurs because the SpinnerLayer is calculated before the TKTransitionSubmitButton has a size (even though it's lazy).
I've. I've moved the spiner.spinnerColor = spinnerColor line to the startLoadingAnimation() function, so the spinner initialisation is delayed until TKTransitionSubmitButton has a concrete size.
