我试图根据将从细分控件触发的排序标准对细胞进行重新排序。我在排序时遇到的问题只是对表格中的标签进行排序,但是一些元素(如文本将根据用户交互而改变的按钮)保持在同一行,这对于单元本身应该更有意义。当点击距离段控件时,请看到差异,它正确地对数据进行排序问题是按钮START ROUTE在第2行时被按下并且变为IN TRANZIT并且现在已经排序它应该在第1行但是不是这里的情况。填充表的数据来自核心数据。有人能指出我正确的方向吗?
func sortData() {
if segment.selectedSegmentIndex == 1 {
dropOffLocations.sort(by: {$0.dateCreated! < $1.dateCreated! })
} else if segment.selectedSegmentIndex == 2 {
dropOffLocations.sort(by: {$0.distance < $1.distance })
} else if segment.selectedSegmentIndex == 3 {
dropOffLocations.sort(by: {$0.postcode! < $1.postcode! })
}
tableView.reloadData()
}
@IBAction func segmentChange(_ sender: Any) {
sortData()
}
@objc func tappedButton(sender : UIButton) {
if let cell = sender.superview?.superview?.superview as? UITableViewCell {
if let indexPath = tableView.indexPath(for: cell) {
let dropOffLocation = dropOffLocations[indexPath.row]
sender.setTitle("IN TRANZIT", for: .normal)
sender.titleLabel?.adjustsFontSizeToFitWidth = true
dropOffLocation.btnStatus = sender.titleLabel?.text
sender.backgroundColor = #colorLiteral(red: 0.05882352963, green: 0.180392161, blue: 0.2470588237, alpha: 0.75)
save(completion: { (true) in
dropOffLocation.setValue("IN TRANZIT", forKey: "btnStatus")
print(dropOffLocation)
})
print(dropOffLocation)
let destinationCoordinate = CLLocationCoordinate2D(latitude: dropOffLocation.latitude, longitude: dropOffLocation.longitude)
let destinationPlacemark = MKPlacemark(coordinate: destinationCoordinate)
let destinationMapItem = MKMapItem(placemark: destinationPlacemark)
destinationMapItem.name = dropOffLocation.street
destinationMapItem.openInMaps(launchOptions: [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving])
}
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "deliveryAddressCell", for: indexPath) as? AddressCell else { return UITableViewCell() }
let dropOffLocation = dropOffLocations[indexPath.row]
cell.startBtn.addTarget(self, action: #selector(self.tappedButton(sender:)), for: .touchUpInside)
cell.startBtn.titleLabel?.adjustsFontSizeToFitWidth = true
cell.startBtn.titleLabel?.minimumScaleFactor = 0.5
cell.startBtn.titleLabel?.numberOfLines = 1
cell.startBtn.titleLabel?.transform = CGAffineTransform(rotationAngle: CGFloat.pi / 2)
cell.configureCell(dropOffLocation: dropOffLocation)
cell.numberLbl.text = String(indexPath.row + 1)
return cell
}
func save(completion: (_ finished: Bool) -> ()) {
guard let managedContext = appDelegate?.persistentContainer.viewContext else { return }
let dropOffLocations = DropOffLocation(context: managedContext)
do {
try managedContext.save()
print("Succesfully saved data!")
completion(true)
} catch {
debugPrint("Could not save: \(error.localizedDescription)")
completion(false)
}
}

你刚刚想出如何处理这件事。首先,我添加了Bool类型的核心数据isINTransit
。在数据模型init中使用false值,当我按下按钮时,我将值设置为true。然后在cellForRowAt
中进行条件检查if是否为true,然后将按钮标题设置为IN TRANZIT,如果为false则将其设置为START ROUTE。
