Description
ScrollView snapToInterval/snapToOffsets not working when the scrollView width is a float number in IOS, because isHorizontal method in RCTEnhancedScrollView return a unexpected result when the width is a float.
- (BOOL)isHorizontal:(UIScrollView *)scrollView
{
return scrollView.contentSize.width > self.frame.size.width;
}
In my reproducer: https://snack.expo.dev/@hiyuki/scrollview-snaptointerval-bug, when i set scrollView's width with a integer, such as 100, snapToInterval/snapToOffsets works fine, but when i set the width with a float number, such as 100.3, snapToInterval/snapToOffsets does't work.
Steps to reproduce
- open the reproducer link: https://snack.expo.dev/@hiyuki/scrollview-snaptointerval-bug
- execute it with expo go in a IOS device
- scroll the scrollView content vertically, snapToInterval/snapToOffsets does't work when touch up

Direzione di ricerca
Inizia dal metodo RCTEnhancedScrollView's isHorizontal: e riproduci il problema usando lo Snack collegato con larghezze di ScrollView intere e in virgola mobile su iOS. Verifica che snapToInterval e snapToOffsets eseguano correttamente lo snap con larghezze frazionarie e controlla il comportamento iOS correlato rispetto alla configurazione React Native 0.76.5 segnalata.
