Crashing on CLLayer position contains NaN

[nnhubbard]

I have been getting some crash reports that show the following:

Fatal Exception: CALayerInvalidGeometry
CALayer position contains NaN: [nan -48.5]

Is there a reason it would be returning NaN? And is there a way I can detect this?

[nnhubbard]

I actually added the following check, but I still get the error:

// now set the *actual* anchor point for our layer so that our "popup" animation starts from this point.
if (isnan(anchorX) || isnan(anchorY)) {
        return;
}
CGPoint anchorPoint = [layer convertPoint:CGPointMake(anchorX, anchorY) toLayer:self.layer];

Hm that's weird - can you reproduce this issue in the sample project?

[nnhubbard]

No I can't. I just get crash logs through Crashlytics about it. I have been getting them since we launched our app in December.

Hi! I get these crashes as well.
@nnhubbard Have you found what's causing it?

[nnhubbard]

@grusha No, have never figured it out. I still get the reports on Crashlytics but cannot reproduce.
