解决scrollview滑动不流畅 #44
Comments
不是这里的原因,改了没用。 |
onScrollShouldSetResponder: () => false, sectionList卡顿是因为我在外层使用了react-native-scrollable-tab-view,按照 #20 修改下就好了,不过滑动还是有一点点问题,就是如果里面的FlatList先上滑再下滑,不会触发下拉刷新,因为手势还是作用在FlatList上,要松一次再下拉,手势才会定在外层ScrollView上。 |
这样改有个问题,由于onScrollShouldSetResponder手势被拦截,在左右滑动的时候就会触发list的item点击事件,左右滑动会进入二级页面,对于使用了ScrollableTabView的页面是可怕的,所以这个方案无效 |
最近我也遇到这个问题~ 所以最后是怎么解决的呢? |
提主的方式有效~值得一试。 仔细看了下我用的Flatlist 中的ScrollView 是我自定义的xxScrollView, 此时就会出现 IOS 滚动不顺滑的现象。 |
我是单层的Flatlist,使用楼主的方法得到了解决 |
is userful |
RCTScrollView.m 里找到这个方法
{
//改动地方在这里
if ([self _shouldDisableScrollInteraction] && ![NSStringFromClass([RCTUIManager JSResponder].class) isEqualToString:@"RCTScrollView"]) {
self.panGestureRecognizer.enabled = NO;
self.panGestureRecognizer.enabled = YES;
// TODO: If mid bounce, animate the scroll view to a non-bounced position
// while disabling (but only if
stopScrollInteractionIfJSHasResponder
was// called during a
pan
). Currently, it will just snap into place which// is not so bad either.
// Another approach:
// self.scrollEnabled = NO;
// self.scrollEnabled = YES;
}
}
