[英]Uibutton issue in swift 3.0
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = UITableViewCell()
if isFacility {
cell = tableView.dequeueReusableCell(withIdentifier: "facilityCell")!
let gameNameLbl = cell.viewWithTag(100) as! UILabel
gameNameLbl.text = "Badminton Court"
let gameImgVw = cell.viewWithTag(101) as! UIImageView
let bookNowBtn = cell.viewWithTag(102) as! UIButton
bookNowBtn.backgroundColor = DEFAULTAPPCOLOR
ConstantFile.makeCornerRoundBtnWithOutBorder(btn: bookNowBtn)
bookNowBtn.tag = indexPath.row
bookNowBtn.addTarget(self, action: #selector(bookCort(sender:)), for: .touchUpInside)
bookNowBtn.setTitle("BOOK NOW", for: .normal)
if indexPath.row % 2 == 0 {
gameImgVw.backgroundColor = UIColor.red
}
else{
gameImgVw.backgroundColor = UIColor.darkText
}
}
else{
cell = tableView.dequeueReusableCell(withIdentifier: "bookingCell")!
let gameImgVw = cell.viewWithTag(103) as! UIImageView
let gameNameLbl = cell.viewWithTag(104) as! UILabel
let gameDateLbl = cell.viewWithTag(105) as! UILabel
let gametimeLbl = cell.viewWithTag(106) as! UILabel
ConstantFile.roundImageViewWithOutBorder(image: gameImgVw)
gameNameLbl.text = "Tennis Court"
gameDateLbl.text = "22 Dec 2017"
gametimeLbl.text = "7:00pm - 9:00pm"
}
return cell
}
在上面的代码中,滚动uibutton的表“致命错误:在打开可选值时意外发现nil”使我崩溃(在这一行中,让bookNowBtn = cell.viewWithTag(102)作为UIButton)。
可能您在StoryBoard中设置了不同的标签值。
