如何在UITableViewCell中实现简单删除(带红色减号按钮)

Question

我正在从表视图中删除单元格,它实现了滑动删除,遵循我正在使用的代码:

#pragma mark -   
#pragma mark Table View Data Source Methods

- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{ 
[super setEditing:editing animated:animated]; 
[addTagTableView setEditing:editing animated:YES];
}

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

 //Updating the data-model array and deleting the row
- (void)tableView:(UITableView *)tv commitEditingStyle:    (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
{
    // If row is deleted, remove it from the list. 
    if (editingStyle == UITableViewCellEditingStyleDelete) 
    {
            [self.tagsArray removeObjectAtIndex:indexPath.row];
        [self.addTagTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

这让我可以实现刷卡删除,但是我想简单的减去红色按钮删除,如何实现呢？

Answer 1

- (void)viewDidLoad {
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

使用此代码,您的应用中会有一个编辑按钮.如果按此按钮,"红色减号"会自动出现:)
