在 tableView 中删除

Posted 2023-02-26

【中文标题】在 tableView 中删除

【英文标题】：delete in tableView

【发布时间】：2010-04-28 06:40:51

【问题描述】：

我只是在 .h 文件中添加这些方法：

- (IBAction)EditTable:(id)sender;

- (IBAction)DeleteButtonAction:(id)sender;

在 .m 文件中：

(IBAction)DeleteButtonAction:(id)sender [tableList removeLastObject]; [表重载数据];

(IBAction) EditTable:(id)sender

如果（self.editing）

[super setEditing:NO animated:NO];
[Table setEditing:NO animated:NO];
[Table reloadData];
[self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
[self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStylePlain];

否则

[super setEditing:YES animated:YES];
[Table setEditing:YES animated:YES];
[Table reloadData];
[self.navigationItem.leftBarButtonItem setTitle:@"Done"];
[self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStyleDone];

当我运行程序并单击删除按钮（红色按钮）时，程序停止！ 有什么问题 ？请帮忙？

你是邪恶的:(

好的，我在 .h 文件中的代码是：

- (IBAction)EditTable:(id)sender;
- (IBAction)DeleteButtonAction:(id)sender;

在 .m 文件中是：

- (IBAction)DeleteButtonAction:(id)sender
    [tableList removeLastObject];
    [Table reloadData];

- (IBAction) EditTable:(id)sender

  if(self.editing)


[super setEditing:NO animated:NO];
[Table setEditing:NO animated:NO];
[Table reloadData];
[self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
        [self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStylePlain];

else

[super setEditing:YES animated:YES];
[Table setEditing:YES animated:YES];
[Table reloadData];
[self.navigationItem.leftBarButtonItem setTitle:@"Done"];
[self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStyleDone];
   

当我运行程序并单击删除按钮（红色按钮）时，程序崩溃了！有什么问题 ？请帮忙？

【参考方案1】：

如果我没记错的话，你想在点击删除按钮时删除 tableView 的单元格......

你需要调用另外一种tableview的方法：

//To Delete the Data
- (void)setEditing:(BOOL)editing animated:(BOOL)animated 
    // Updates the appearance of the Edit|Done button as necessary.
    [super setEditing:editing animated:animated];
    [tblViewBM setEditing:editing animated:YES];
    // Disable the add button while editing.



- (void)tableView:(UITableView *)tableView commitEditingStyle:
(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 

 if (editingStyle == UITableViewCellEditingStyleDelete) 

//Use your Array from which you need to delete the data.
  NSMutableDictionary *dict=(NSMutableDictionary *)[appDel.BookMarkAry objectAtIndex:indexPath.row];
  type=[dict valueForKey:@"type"];

  [appDel.BookMarkAry removeObjectAtIndex:indexPath.row];


  [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];


  [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
  

我相信这肯定会帮助您从数组中删除包含数据的单元格。
