Описание
Кажется, когда я запускаю длинное нажатие WKWebView для предварительного просмотра изображения. Я знаю, что это вызвано делением числа на ноль. Может быть, это ошибка WebKit самостоятельно. Но что мне делать с этим сбоем？
Cra sh причина:
CALayerInvalidGeometry
CALayer bounds contains NaN: [0 nan; 5.33459e-314 2.79601e-314]. Layer: <CALayer:0x2805b7960; position = CGPoint (3.93407e-314 2.16644e-314); bounds = CGRect (0 0; 0 0); delegate = <_UIPreviewPlatterView: 0x151321450; frame = (3.93407e-314 2.16644e-314; 0 0); gestureRecognizers = <NSArray: 0x280bc9230>; layer = <CALayer: 0x2805b7960>>; sublayers = (<CALayer: 0x2805b1400>, <CALayer: 0x2805b76c0>, <CALayer: 0x2805b7820>); opaque = YES; allowsGroupOpacity = YES; >
