xcode 8 swift 3 UItableview space between cells? - ios

Question

i am trying to make space between cells in UItableview i've checked google all posts i found is more than 3 years old , when i try to apply them i am getting so many errors, is it possible to make space between cells in UItableview ?
my Code :
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)
}
The class of TableCell :
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
}
}

Make Tablview BG colour white and set BG View colour in cell that you want to keep see in image i have set bgview BG colour is light greay and make BGview hight smaller then cell i mean if you want to set space 10 pixel keep Bg hight smaller then cell 10 pixel
Here is my cell
And here is out put

Update: UIEdgeInsetsInsetRect method is replaced now you can do it like this
contentView.frame = contentView.frame.inset(by: margins)
Swift 4 answer:
in your custom cell class add this function
override func layoutSubviews() {
super.layoutSubviews()
//set the values for top,left,bottom,right margins
let margins = UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
contentView.frame = UIEdgeInsetsInsetRect(contentView.frame, margins)
}
You can change values as per your need

Swift 4.2 solution
Inside UITableViewCell subclass
override func layoutSubviews() {
super.layoutSubviews()
let padding = UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
bounds = bounds.inset(by: padding)
}
Swift 5.0 solution
Inside UITableViewCell subclass
override func layoutSubviews() {
super.layoutSubviews()
let padding = UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
bounds = UIEdgeInsetsInsetRect(bounds, padding)
}

You can let every cell to take a section in group tableView, then you set the section's footer.
Try my code:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
tableView.register(UINib.init(nibName: "VC1Cell", bundle: nil), forCellReuseIdentifier: "VC1Cell")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: -- tableview delegate
func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let view:UIView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: self.view.bounds.size.width, height: 10))
view.backgroundColor = .clear
return view
}
func numberOfSections(in tableView: UITableView) -> Int {
return 10
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 44
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:VC1Cell = tableView.dequeueReusableCell(withIdentifier: "VC1Cell") as! VC1Cell
return cell
}
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return 10.0
}
}
The result:

Building on Gulfam Khan's answer, the new way of setting the inset:
Swift 4:
override func layoutSubviews() {
super.layoutSubviews()
//set the values for top,left,bottom,right margins
let margins = UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
contentView.frame = contentView.frame.inset(by: margins)
}

Answer 6

Swift 4:
override func layoutSubviews() {
super.layoutSubviews()
contentView.frame = contentView.frame.inset(by: UIEdgeInsets(top: 10, left: 0, bottom: 10, right: 0))
}

Swift 5.2 Solution
override func layoutSubviews() {
super.layoutSubviews()
let padding = UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
bounds = bounds.inset(by: padding)
}
