由于水平滚动视图,我有主表视图,其中集合视图在表视图节标题中已确定。当我点击集合视图(第1行)表视图重新加载。但是当我点击集合视图第5行时,它会重新加载表视图并从头开始显示集合滚动位置。请帮我设置表视图内的集合视图的手动滚动位置。
以下是我正在使用的代码。
func numberOfSections(in tableView: UITableView) -> Int
{
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
if section == 0
{
return 1
}
else
{
return 1
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
if indexPath.section == 0
{
let cell = tableView.dequeueReusableCell(withIdentifier: "banTableViewCell", for: indexPath) as! banTableViewCell
return cell
}
else
{
if chkVal == 0
{
let cell = tableView.dequeueReusableCell(withIdentifier: "onepageTableViewCell", for: indexPath) as! onepageTableViewCell
return cell
}
else if chkVal == 1
{
let cell = tableView.dequeueReusableCell(withIdentifier: "onepageTableViewCell", for: indexPath) as! onepageTableViewCell
return cell
}
else if chkVal == 2
{
let cell = tableView.dequeueReusableCell(withIdentifier: "onepageTableViewCell", for: indexPath) as! onepageTableViewCell
return cell
}
else if chkVal == 3
{
print("its cming gallery there")
let cell = tableView.dequeueReusableCell(withIdentifier: "containerTableViewCell", for: indexPath) as! containerTableViewCell
return cell
}
else
{
print("its cming calendar there")
let cell = tableView.dequeueReusableCell(withIdentifier: "galTableViewCell", for: indexPath) as! galTableViewCell
return cell
}
}
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
if section == 0
{
let view = UIView(frame: CGRect(x:0, y:0, width:0, height:0))
return view
}
else
{
let SegCell = tableView.dequeueReusableCell(withIdentifier: "segTableViewCell") as! segTableViewCell
SegCell.segcol.dataSource = self as UICollectionViewDataSource
SegCell.segcol.delegate = self as UICollectionViewDelegate
SegCell.segcol.isPagingEnabled = true
SegCell.segcol.isScrollEnabled = true
SegCell.segcol.showsHorizontalScrollIndicator = true
SegCell.segcol.register(UINib(nibName: "segCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "segCollectionViewCell")
// Initialization code
let indexPath = NSIndexPath(row: 3, section: 0)
SegCell.segcol.scrollToItem(at: indexPath as IndexPath, at: UICollectionViewScrollPosition.right, animated: false)
return SegCell
}
}
//Collection View Set
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
return 5
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "segCollectionViewCell", for: indexPath as IndexPath) as! segCollectionViewCell
if indexPath.row == 0
{
cell.TextSeg.text = "FITNESS REPORT CARD"
}
else if indexPath.row == 1
{
cell.TextSeg.text = "FITNESS STATS"
}
else if indexPath.row == 2
{
cell.TextSeg.text = "DIET & NUTRITION"
}
else if indexPath.row == 3
{
cell.TextSeg.text = "GALLERY"
}
else if indexPath.row == 4
{
cell.TextSeg.text = "CALENDAR"
}
return cell
}
func collectionView(_ collectionView: UICollectionView,layout collectionViewLayout: UICollectionViewLayout,
sizeForItemAt indexPath: IndexPath) -> CGSize
{
return CGSize(width:150, height:46)
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath)
{
if indexPath.row == 0
{
tbl.reloadData()
}
else if indexPath.row == 1
{
tbl.reloadData()
}
else if indexPath.row == 2
{
tbl.reloadData()
}
else if indexPath.row == 3
{
tbl.reloadData()
}
else if indexPath.row == 4
{
tbl.reloadData()
}
}
它没有在集合视图中设置滚动位置。
