UITableView编辑模式

Question

我有UITableView,我正在尝试在编辑模式下默认加载它.问题是当我这行table.editing=TRUE;我的行消失时,我实现了这个方法:

- (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;
 }

但没有运气.我该怎么办？

Answer 1

正如Anish所指出的那样

[tableView setEditing: YES animated: YES]; 

但是你需要在viewWillAppear视图中使用它才能使它工作.

Answer 2

试试这个...

[tableView setEditing: YES animated: YES];

Answer 3

在ViewDidLoad中写

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];
    }
}

对于Row的MultipleSelection

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

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

注意:有三种编辑风格如下

UITableViewCellEditingStyleNone,
UITableViewCellEditingStyleDelete,
UITableViewCellEditingStyleInsert

注意:对于多个选择集,从属性检查器中选择和编辑样式为多个
