[英]UITableView not scrolling properly to bottom until a cell is clicked
[英]UITableview scrolling is not responding properly?
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!
}
上面顯示的代碼用於書本桌子,它有時像普通紙一樣滾動,有時根本不滾動。 我正在以編程方式執行所有代碼。 我已經在模擬器和設備上對此進行了測試,但是仍然存在問題。 任何幫助表示贊賞...
創建自定義UITableViewCell
,假設它是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
}
}
我已經用xib
這樣創建了UITableViewCell
並綁定了IBOutlets
假設我們有這樣的struct Model
和array
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)
}
現在在ViewController
viewDidLoad()
方法上,
tableView.register(UINib(nibName: "ListTableCell", bundle: nil), forCellReuseIdentifier: "ListTableCell")
實現這樣的UITableViewDataSource
方法,
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
對於不同的表視圖,您可以以相同的方式創建不同的自定義單元格,並且cellForRowAt indexPath
和numberOfRowsInSection
方法將適當地更改。
如有任何疑問,請通知我。
