我有一个包含多个UITableviews的视图控制器。我想从表视图中删除行以删除与此行关联的通知时,这是我的代码,但我收到错误Index out of range
这里是我的项目的链接,如果有人想测试它:{{3 }}
我的代码:它没有简单的字符串,但是索引行我得到了错误。
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
if tableView == ScheduleTableView{
let defaults = UserDefaults.standard
var myarray = defaults.stringArray(forKey: "ScheduleArray") ?? [String]()
var myarray2 = defaults.stringArray(forKey: "ScheduleTimeArray") ?? [String]()
// Remove Row
myarray.remove(at: indexPath.row)
myarray2.remove(at: indexPath.row)
defaults.set(myarray, forKey: "ScheduleArray")
defaults.set(myarray2, forKey: "ScheduleTimeArray")
ScheduleTableView.deleteRows(at: [indexPath], with: .fade)
UserDefaults.standard.synchronize()
// Remove Notification
let center = UNUserNotificationCenter.current()
let arrayToSearch = myarray[indexPath.row] as String
center.getPendingNotificationRequests { (notifications) in
for item in notifications {
if(item.identifier.contains(arrayToSearch)) {
center.removePendingNotificationRequests(withIdentifiers: [item.identifier])
}
}
}
}
if tableView == GoalsTableView{
}
}
答案 0 :(得分:1)
删除此行let arrayToSearch = myarray[indexPath.row] as String
并使用已删除的项目,因为您已经删除了myarray.remove(at: indexPath.row)
以下是代码:
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
if tableView == ScheduleTableView{
// Here is my code but it gives me an error, first you need to add a row with the add button
let defaults = UserDefaults.standard
var myarray = defaults.stringArray(forKey: "ScheduleArray") ?? [String]()
print(myarray)
let removedItem = myarray.remove(at: indexPath.row)
defaults.set(myarray, forKey: "ScheduleArray")
ScheduleTableView.deleteRows(at: [indexPath], with: .fade)
// Remove Notification
let center = UNUserNotificationCenter.current()
center.getPendingNotificationRequests { (notifications) in
for item in notifications {
if(item.identifier.contains(removedItem)) {
center.removePendingNotificationRequests(withIdentifiers: [item.identifier])
}
}
}
}
if tableView == GoalsTableView{
}
}
