我试图做一个应用程序,存储个人信息可以删除,编辑使用editActionsForRowAtIndexPath
。删除选项似乎工作正常,但我遇到编辑操作的问题。刷卡swift编辑sqlite数据库内容
我得到一个错误,因为我已经提到如下:
Could not cast value of type 'Table_view.UserTableViewController' (0x10a1991b0) to 'NSIndexPath' (0x10a5e8438).
UserRecordViewController
是视图控制器,其中个人信息将被显示。而InsertRecordViewController
是另一个View Controller。
UserTableViewController
相关代码:
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
// 1
let editAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Edit" , handler: { (action:UITableViewRowAction, indexPath:NSIndexPath) -> Void in
self.performSegueWithIdentifier("editSegue", sender: self)
})
editAction.backgroundColor = UIColor.darkGrayColor()
// let editIndex = editAction.indexOfAccessibilityElement(indexPath.row)
let deleteAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Delete" , handler: { (action:UITableViewRowAction, indexPath:NSIndexPath) -> Void in
let userInfo: UserInfo = self.marrUserData.objectAtIndex(indexPath.row) as! UserInfo
let isDeleted = ModelManager.getInstance().deleteUserData(userInfo)
if isDeleted {
Util.invokeAlertMethod("", strBody: "Record deleted successfully.", delegate: nil)
} else {
Util.invokeAlertMethod("", strBody: "Error in deleting record.", delegate: nil)
}
self.getUserData()
})
deleteAction.backgroundColor = UIColor.lightGrayColor()
return [deleteAction, editAction]
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if(segue.identifier == "editSegue"){
let selectedIndexPath = sender as! NSIndexPath
let index = selectedIndexPath.row
//if let indexPath: NSIndexPath = self.tableView.indexPathForCell(sender as! UITableViewCell) {
//let btnEdit : UIButton = sender as! UIButton
//let selectedIndex : Int = btnEdit.tag
let viewController : InsertRecordViewController = segue.destinationViewController as! InsertRecordViewController
viewController.isEdit = true
viewController.userData = self.marrUserData.objectAtIndex(index) as! UserInfo
// }
}
}
我想知道我要去哪里错了。任何想法的家伙?
在此先感谢!
对不起,但如何在func prepareForSegue中有用? –
ThanQ! :)有关如何访问UITableViewCell到我的UserTableViewController的任何想法? –
什么?我不明白你想要做什么 – ale00
