CALayerInvalidGeometry

[aybar]

Hi @alskipp,

Following the 0.9.1 update, I start to experience crash. Here is the output:

Do you have any idea of what's going on?

It is currently working fine with 0.9.0

Hi @aybar I believe this is likely the same issue as #18

I've just updated the master branch which I believe should fix the issue (new podspec hasn't been released yet). Could you try the current master, or the quick fix I posted in #18 to see if this fixes the crash for you?

Thanks,
Al

Oh, thanks! With master branch it is working ;)

[alskipp]

Brilliant, that's a relief! I'll update the podspec later today. Thanks for raising the issue.

By the way, current master branch introduces a new feature:

@protocol ASValueTrackingSliderDataSource <NSObject>
- (NSString *)slider:(ASValueTrackingSlider *)slider stringForValue:(float)value;
@end

It allows you to supply custom NSStrings to display in the popUpView - the example app gives a demonstration.

wow, nice function! thanks for the impressive work!!
