Crash when setting CALayer's frame

[cravemusic]

Overall setup:
View controller inside of a popover
Add slider as only view in VC's viewDidLoad, no XIBs or Storyboards involved

Crash here:

[ASValuePopUpView setArrowCenterOffset:]
[ASValueTrackingSlider adjustPopUpViewFrame]
[ASValueTrackingSlider positionAndUpdatePopUpView]
[ASValueTrackingSlider setup]
[ASValueTrackingSlider initWithFrame:]  // crash with either CGRectZero or CGRectMake(0, 0, 320, 30)
[MyViewController viewDidLoad]
[UIViewController loadViewIfRequired] ()
[UIViewController view] ()
[UINavigationController preferredContentSize] ()
[UIViewController(UIPopoverController_Internal) _resolvedPreferredContentSize] ()
[UIPopoverController _transitionFromViewController:toViewController:animated:] ()
[UIPopoverController _initWithContentViewController:popoverControllerStyle:] ()

on line

self.layer.frame = f; // changing anchor repositions layer, so must reset frame afterwards

CGRect f = self.layer.frame;  // This looks like CGRectZero before crash

Message:
*** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan 0]'

iOS SDK 7.1, iOS 7.1.1

Thank you for reporting this. I think a quick fix for the issue would be this: In the method - (void)setup of ASValueTrackingSlider.m, replace the following line

self.popUpView = [[ASValuePopUpView alloc] initWithFrame:CGRectZero];

with this:

self.popUpView = [[ASValuePopUpView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];

I will investigate this further to work out if this is the best way to solve the problem.
Do let me know if this quick fix solves the issue for you.

Cheers,
Al

Fixed in current master branch. Podspec will be updated later today.
