在tableView中删除 [英] delete in tableView

问题描述

我只是在.h文件中添加此方法：

I just add this methods in .h file :

- (IBAction)EditTable:(id)sender;

- （IBAction）DeleteButtonAction：（id）sender;

- (IBAction)DeleteButtonAction:(id)sender;

和.m文件：

• （IBAction）DeleteButtonAction：（id）sender {
  [tableList removeLastObject];
  [表格重新加载];
  }

• (IBAction)DeleteButtonAction:(id)sender{ [tableList removeLastObject]; [Table reloadData]; }

（IBAction）EditTable：（id）发件人{

(IBAction) EditTable:(id)sender{

如果（ self.editing）

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
{

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）时程序停止！
是什么问题？请帮忙吗？

好的，我的.h文件中的代码是：

OK, again my code in .h file is :

- (IBAction)DeleteButtonAction:(id)sender;

和.m文件中：

- (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！有什么问题 ？请帮忙吗？

推荐答案

如果我没有错，那么你想在单击删除按钮时删除tableView的单元格。 ...

If I am not wrong then you want to delete the cell of the tableView when delete button is clicked....

您需要调用另一种tableview方法：

You need to call one other method of tableview:

//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你删除包含数组数据的单元格。

I am sure this will Definately help you to delete the cell with data from array also.
