UITableview scrolling is not responding properly? - ios

Question

booktable.frame = CGRect(x: 0, y: booktopview.bounds.height, width: screenWidth, height: screenHeight-booktopview.bounds.height-tabbarView.bounds.height)
booktable.register(UITableViewCell.self, forCellReuseIdentifier: "mycell")
booktable.dataSource = self
booktable.delegate = self
booktable.separatorColor = UIColor.lightGray
booktable.backgroundColor = UIColor.clear
booktable.separatorStyle = .singleLine
bookview.addSubview(booktable)
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if(tableView == booktable)
{
let cell1 = booktable.dequeueReusableCell(withIdentifier: "mycell")
for object in (cell1?.contentView.subviews)!
{
object.removeFromSuperview();
}
let img :UIImageView = UIImageView()
let lbl : UILabel = UILabel()
img.frame = CGRect(x: 15, y: 15, width: 80, height: 130)
img.image = imgarray[indexPath.row]
img.layer.borderWidth = 1.0
img.layer.borderColor = UIColor.lightGray.cgColor
cell1?.contentView.addSubview(img)
imgheight = img.bounds.height
lbl.frame = CGRect(x: img.bounds.width + 40, y: (imgheight+40-80)/2, width: booktable.bounds.width-img.bounds.width + 40 - 100, height: 80)
lbl.text = imgname[indexPath.row]
lbl.numberOfLines = 0
lbl.textAlignment = .left
lbl.font = UIFont(name: "Arial", size: 23)
lbl.textColor = UIColor.black
cell1?.selectionStyle = .none
cell1?.contentView.addSubview(lbl)
return cell1!
}
The code shown above is for book table, which sometimes scrolls like normal and sometimes not scrolling at all. I am doing all the code programatically. I have tested this on both simulators and devices but still the problem exists. Any help is appreciated...

Create Custom UITableViewCell, let's say it is ListTableCell
class ListTableCell: UITableViewCell {
#IBOutlet weak var lblTemp: UILabel!
#IBOutlet weak var imgTemp: UIImage!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
I've created UITableViewCell with xib like this and bind IBOutlets
Let's say we have struct Model and array like this
struct Model {
let image : UIImage
let name: String
}
for i in 0...10 {
let model = Model(image: #imageLiteral(resourceName: "Cat03"), name: "Temp \(i)")
array.append(model)
}
Now on ViewController viewDidLoad() method,
tableView.register(UINib(nibName: "ListTableCell", bundle: nil), forCellReuseIdentifier: "ListTableCell")
Implement UITableViewDataSource methods like this,
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return array.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ListTableCell") as! ListTableCell
let model = array[indexPath.row]
cell.lblTemp.text = model.name
cell.imgTemp.image = model.image
return cell
}
FYI
For different tableviews, you can create different custom cell the same way and cellForRowAt indexPath and numberOfRowsInSection method will change appropriately.
Let me know in case of any queries.
UPDATE
Follow this and this to create CustomTableCell programmatically
