在我的应用程序中,我已滑动以在分段控件中删除,并且它通过显示两个不同的表视图来工作,但是我只希望滑动以删除并报告以在我的情况0中显示,而不是在我的情况1中显示(因为情况1)包含其他用户当前用户无法删除或报告的数据)。
我尝试使用:
if mySegmentedControl.selectedSegmentIndex == 0 {
return UISwipeActionsConfiguration(actions: [delete, report])
}
else {
return nil
}
但这仅删除了报告按钮,而不删除了删除按钮?为什么是这样?
这是我的删除和报告代码的滑动:
@available(iOS 11.0, *)
func tableView(_ tableView: UITableView,
trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) ->
UISwipeActionsConfiguration? {
let delete = UIContextualAction(style: .destructive, title: "Delete") { (action, view, nil) in
Database.database().reference().child("messages").child(self.currentUserID!).child(self.message[indexPath.row].messageID).setValue([])
}
let report = UIContextualAction(style: .destructive, title: "Report") { (action, view, nil) in
let areUSureAlert = UIAlertController(title: "Are you sure you want to report?", message: "This will block this user from message you.", preferredStyle: UIAlertControllerStyle.alert)
areUSureAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
Database.database().reference().child("messages").child(self.currentUserID!).child(self.message[indexPath.row].messageID).setValue([])
let blockedPost = ["timestamp" : [".sv" : "timestamp"]]
Database.database().reference().child("blocked").child(self.currentUserID!).child(self.message[indexPath.row].fromID).setValue(blockedPost)
}))
areUSureAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
//dismiss(animated: true, completion: nil)
}))
self.present(areUSureAlert, animated: true, completion: nil)
}
report.backgroundColor = #colorLiteral(red: 0.9529411793, green: 0.8918681279, blue: 0, alpha: 1)
if mySegmentedControl.selectedSegmentIndex == 0 {
return UISwipeActionsConfiguration(actions: [delete, report])
}
else {
return nil
}
}
最佳答案
在此处找到解决方案:Delete button is automatically implemented on swipe despite not implementing trailing swipe action in tableview
通过实施:
return UISwipeActionsConfiguration.init()
代替
return nil
