UITableViewCells重复内容的问题

Question

我的应用程序显示了用户的本地巴士发车时间，但是，如下面的屏幕截图所示，当滚动后夜间巴士在其他服务中开始显示红色的'N'时，此外，路线号也开始错误。滚动时的其余时间，路线编号是正确的，只有当出现夜间巴士时

这是我为设置路线号而执行的代码

case "N3", "N7", "N11","N16","N22","N25","N26","N30","N31","N34", "N37","N44","N98", "N106","N113","N124":

var route = NSMutableAttributedString()

route = NSMutableAttributedString(string: departureRoutes[0].rawString()!)

route.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.red, range: NSRange(location:0,length:1))

route.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.white, range: NSRange(location:1,length:(departureRoutes[0].string?.count)! - 1))

cell.route.setAttributedTitle(route, for: .normal)       

default : 

cell.route.tintColor = routeColor(routeno: departureRoutes[0].rawString()!)

Answer 1

Mohamed Mostafa在评论中建议的解决方案是重置UIButton的值并使用再次设置该值

cell.route.setAttributedTitle(NSMutableAttributedString(string: "\(departureRoutes[indexPath.row + 1])"), for: .normal)

然后在此之后执行切换代码
