我正在努力使单元格之间的空间在UItableview
我已经检查谷歌所有帖子我发现是3岁以上,当我尝试应用他们我得到这么多的错误,是否有可能使单元格之间的空间UItableview
?xcode 8 swift 3单元格之间的UItableView空间?
我的代码:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ImageCell") as! ImageCell
cell.model = self.modelAtIndexPath(indexPath)
let url = URL(string: cell.model.imageName)
cell.imgBack.kf.setImage(with: url)
return cell
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
//send back playlist count
if (section == 0) {
return self.lists_arr.count
}
return 0
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated:true)
}
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
let imageCell = cell as! ImageCell
self.setCellImageOffset(imageCell, indexPath: indexPath)
}
//number of sections in table
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func modelAtIndexPath(_ indexPath: IndexPath) -> CellPlaylist {
return self.lists_arr[(indexPath as NSIndexPath).row % self.lists_arr.count]
}
func scrollViewDidScroll(_ scrollView: UIScrollView) {
if (scrollView == self.tblMain) {
for indexPath in self.tblMain.indexPathsForVisibleRows! {
if let imgCel : ImageCell = self.tblMain.cellForRow(at: indexPath) as? ImageCell {
self.setCellImageOffset(imgCel, indexPath: indexPath)
}
}
}
}
func setCellImageOffset(_ cell: ImageCell, indexPath: IndexPath) {
let cellFrame = self.tblMain.rectForRow(at: indexPath)
let cellFrameInTable = self.tblMain.convert(cellFrame, to:self.tblMain.superview)
let cellOffset = cellFrameInTable.origin.y + cellFrameInTable.size.height
let tableHeight = self.tblMain.bounds.size.height + cellFrameInTable.size.height
let cellOffsetFactor = cellOffset/tableHeight
cell.setBackgroundOffset(cellOffsetFactor)
}
类的TableCell的:
class ImageCell: UITableViewCell {
@IBOutlet weak var lblTitle: UILabel!
@IBOutlet weak var imgBack: UIImageView!
@IBOutlet weak var imgBackTopConstraint: NSLayoutConstraint!
@IBOutlet weak var imgBackBottomConstraint: NSLayoutConstraint!
let imageParallaxFactor: CGFloat = 70
var imgBackTopInitial: CGFloat!
var imgBackBottomInitial: CGFloat!
var model: CellPlaylist! {
didSet {
self.updateView()
}
}
override func awakeFromNib() {
self.clipsToBounds = true
self.imgBackBottomConstraint.constant -= 2 * imageParallaxFactor
self.imgBackTopInitial = self.imgBackTopConstraint.constant
self.imgBackBottomInitial = self.imgBackBottomConstraint.constant
}
func updateView() {
// self.imgBack.imageFromServerURL(urlString: self.model.imageName)
//self.getImage(url: self.model.imageName,imgView: self.imgBack)
//self.model.imageName
self.layer.cornerRadius = 10
self.layer.masksToBounds = true
self.layer.cornerRadius = 8
self.layer.shadowOffset = CGSize(width: 0, height: 3)
self.layer.shadowRadius = 3
self.layer.shadowOpacity = 0.3
self.layer.shadowPath = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: .allCorners, cornerRadii: CGSize(width: 8, height: 8)).cgPath
self.layer.shouldRasterize = true
self.layer.rasterizationScale = UIScreen.main.scale
self.contentView.layoutMargins.top = 20
self.lblTitle.text = self.model.title
}
func setBackgroundOffset(_ offset:CGFloat) {
let boundOffset = max(0, min(1, offset))
let pixelOffset = (1-boundOffset)*2*imageParallaxFactor
self.imgBackTopConstraint.constant = self.imgBackTopInitial - pixelOffset
self.imgBackBottomConstraint.constant = self.imgBackBottomInitial + pixelOffset
}
}

我想要什么:
变化'view' UITableCell' – Dhiru
的'了'contentView'内部框架有每一个细胞是属于单独部分的一部分。并给每个部分一个透明的footerView。或者在你的单元格内创建一个视图,并让单元格contentView透明。创建的视图对具有所需间距的contentView有一个底部约束。因为我正在下班,所以无法给出完全成熟的答案。如果你不能工作出来提及它,我会看到关于帮助你以后 – DatForis
@Dhiru我这样做仍然没有间距 –
