Issue:
The separator line of previous cell disappears when the cell expand and collapse.
Reason:
It seems like an iOS 7 bug.
My project is based on iOS 8. The bug still exists.
According to to this stackowerflow question:
UITableView separator line disappears when selecting cells in iOS7
I was able to fix it淌喻！
We need add this lines:
func treeView(treeView: RATreeView, didSelectRowForItem item: AnyObject) {
treeView.deselectRowForItem(item, animated: true)
treeView.reloadRowsForItems([item],
withRowAnimation: RATreeViewRowAnimation(UInt32(UITableViewRowAnimation.None.rawValue)))
}
Fix method of iOS system tableview:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .None)
}
