ios - 打开另一个 View 并取消后选择的单元格

Question

在我单击一个单元格来编辑对象后，该单元格会打开另一个 VC 来允许编辑，但如果用户单击取消，该单元格仍会被选中，并很快导致问题和崩溃。

单元格编辑:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

    if ([segue.identifier isEqualToString:@"addAssignment"])
    {
        AddEditViewController *addEditController = segue.destinationViewController;
        [addEditController setOtherdelegate:self];
    }


   if ([segue.identifier isEqualToString:@"edit"]) {
    UITableViewCell *cell = sender;
    AddEditViewController *addEditController = segue.destinationViewController;
    [addEditController setOtherdelegate:self];
    addEditController.edit = YES;
    AssignmentInfo *a = [self.alist objectAtIndex:[self.tableView indexPathForCell:cell].row];
    addEditController.assignmentEditing = a;

    [self.alist removeObject:a];
    [self.tableView reloadData];
    NSString *filePath = [self dataFilePath];
    [NSKeyedArchiver archiveRootObject:self.alist toFile:filePath];
    }
}

按下取消按钮:

- (IBAction)addAssignmentCancelButtonPressed:(id)sender {
    [self dismissViewControllerAnimated:YES completion:nil];
}

Answer 1

首先你要做的是删除这一行:

[self.alist removeObject:a]; 

你的下一个:-(void)newAssignment:(AssignmentInfo *)assignment 删除:

  [self.tableView reloadData];

并添加:

 [self.tableView reloadData];

到 -(void)deletedAssignment:(AssignmentInfo *)assignment

在你的最后:-(void)newAssignment:(AssignmentInfo *)assignment 删除:

  NSString *filePath = [self dataFilePath];
[NSKeyedArchiver archiveRootObject:self.alist toFile:filePath];

并添加:

NSString *filePath = [self dataFilePath];
[NSKeyedArchiver archiveRootObject:self.alist toFile:filePath];

到 -(void)deletedAssignment:(AssignmentInfo *)assignment
