UITableView编辑模式

Question

I have UITableView and I am trying to load it by default in edit mode. The problem is when I this line table.editing=TRUE; my rows disappear, I implemented this methods:

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath 
{
// Return NO if you do not want the specified item to be editable.
return YES;
}

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath 
{
return UITableViewCellEditingStyleDelete;
}


 - (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath 
 {
 return NO;
 }

but with no luck. What should I do?

Answer 1

as Anish pointed to using

[tableView setEditing: YES animated: YES]; 

But you need to have it in viewWillAppear view event to make it work.

Answer 2

试试这个...

[tableView setEditing: YES animated: YES];

Answer 3

In ViewDidLoad write

UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style: UIBarButtonItemStyleBordered target:self action:@selector(addORDoneRows)];
[self.navigationItem setLeftBarButtonItem:addButton];

addORDoneRow

- (void)addORDoneRows
{
    if(self.editing)
    {
        [super setEditing:NO animated:NO];
        [_dbSongsTblView setEditing:NO animated:NO];
        [_dbSongsTblView reloadData];
        [self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
        [self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStylePlain];
    }
    else
    {
        [super setEditing:YES animated:YES];
        [_dbSongsTblView setEditing:YES animated:YES];
        [_dbSongsTblView reloadData];
        [self.navigationItem.leftBarButtonItem setTitle:@"Done"];
        [self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStyleDone];
    }
}

For MultipleSelection of Row

 - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
    return YES;
}

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewCellEditingStyleNone;
}

Note: There are Three Editiing Style as below

UITableViewCellEditingStyleNone,
UITableViewCellEditingStyleDelete,
UITableViewCellEditingStyleInsert

Note: And for multiple Selection set Selection and Editing Style to Multiple from Attribute inspector

Answer 4

To load a tableView in edit mode you should call setEditing(true, animated: false) in viewDidLoad() .

If your view controller is a subclass of UITableViewController there's no need to change, just make the above call. Otherwise if your view controller is a subclass of UIViewController, then you should make a call in this way: tableView.setEditing(true, animated: true) .

Tested with Swift 2.2.

Answer 5

[self.tableView setEditing：！self.tableView.isEditing animated：YES];
