滑动以删除按钮替换的操作

Question

  

可能重复：
  Replace action of swipe to delete by clicking on a button

我有以下代码。

- (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [appointments removeObjectAtIndex: indexPath.row];  // manipulate your data structure.
        [tableView deleteRowsAtIndexPaths: [NSArray arrayWithObject: indexPath]
                         withRowAnimation: UITableViewRowAnimationFade];
       NSLog(@"row deleted");  // Do whatever other UI updating you need to do.
    }
} 

当我在单元格上滑动时，这段代码将被执行。但我想要的是当我按下自定义tableview单元格中的按钮时，此代码会执行。就像你在下面的截图中看到的那样，我的桌面视图上有2个按钮。

当用户按下“X”按钮时，删除按钮应该像滑动单元格时一样展开。我的单元格附加了以下操作。

-(IBAction) deleteAppointment:(id) sender{
   //show swipe delete button
}

并按照以下方式将其附加到我的cellForRowAtIndex中。

cell.deleteAppointment.tag = indexPath.row;
[cell.deleteAppointment addTarget:self action:@selector(deleteAppointment:) forControlEvents:UIControlEventTouchUpInside];

只需在单元格中添加按钮，并将标记设置为每个按钮，如下所示..

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    /////your code
    UIButton *btnClose = [[UIButton alloc]initWithFrame:CGRectMake(270, 7, 20, 20)];
    btnClose.tag = indexPath.row;
    [btnClose setImage:[UIImage imageNamed:@"closeImage.png"] forState:UIControlStateNormal];
    [btnClose addTarget:self action:@selector(deleteAppointment:) forControlEvents:UIControlStateNormal];
    [cell addSubview:btnClose];
    return cell;
}

并且在方法中看到这样......

    - (IBAction)deleteAppointment:(id)sender {

            // here bellow code for swipe the close button in cell
            UIButton *btn = (UIButton *)sender;
            int SelectedRowNo = btn.tag;
            [UIView beginAnimations:nil context:NULL];
            [UIView setAnimationDuration:0.3];
            [btn setFrame:CGRectMake(btn.frame.origin.x - 50, btn.frame.origin.y, btn.frame.size.width, btn.frame.size.height)];
            [UIView commitAnimations];

            //// here bellow code for delete raw from table
            /*
             [appointments removeObjectAtIndex: SelectedRowNo];
             UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
             NSIndexPath *clickedButtonPath = [yourTableView indexPathForCell:clickedCell];
             [yourTableView deleteRowsAtIndexPaths: [NSArray arrayWithObject: clickedButtonPath]
             withRowAnimation: UITableViewRowAnimationFade];
             NSLog(@"row deleted");  // Do whatever other UI updating you need to do.
             */
}

我希望这可以帮到你..
