问题描述
我有一个扩展/折叠其单元格的表格视图。
I have a table view which expands/collapse its cells.
从iOS 11开始,tableView在插入和删除行时开始表现奇怪。
在动画块发生之前,contentSize已经更改,因此,在视频中,您可以看到在折叠单元格上发生错误回滚。动画看起来不错。
As of iOS 11, the tableView starts to behave strangely on insertion and deletion of rows.The contentSize has changed before the animation block happens and consequently, in the video, you can see a buggy scroll back happening on collapsing cells. The animation just looks wrong.
这段代码在iOS 10上完美运行。有人知道Apple方面有什么变化吗?这是一个已知的问题?
This code worked perfectly on iOS 10. Do anyone know what has changed on Apple's side? Is this a known issue?
public func insertingRowsForAccordion(_ indexArray: [IndexPath], selectedRowIndex: Int) {
beginUpdates()
insertRows(at: indexArray, with: UITableViewRowAnimation.fade)
endUpdates()
// Scroll to selection after expanding children
scrollToRow(at: IndexPath(row: selectedRowIndex, section: 0), at: UITableViewScrollPosition.top, animated: true)
}
public func removeRowsForAccordion(_ indexArray: [IndexPath]) {
beginUpdates()
deleteRows(at: indexArray, with: UITableViewRowAnimation.fade)
endUpdates()
}
