UITableView commitEditingStyle没有删除单元格

我在UITableView中删除行的概念存在小问题。用户删除一行后我不想触发:

    [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];

相反,我希望更改已编辑的单元格文本和背景而不隐藏它。我的方法很有效:

if (editingStyle == UITableViewCellEditingStyleDelete) {
    NSMutableArray *previous_points = [self.trip_arrayOfAllPoints mutableCopy];
    [previous_points removeObjectAtIndex:indexPath.row];
    self.trip_arrayOfAllPoints = nil;

    self.trip_arrayOfAllPoints = [[NSMutableArray alloc] initWithCapacity:[previous_points count]];
    self.trip_arrayOfAllPoints = [previous_points mutableCopy];

    self.trip_arrayOfAllPointsEDITED = [[NSMutableArray alloc] initWithCapacity:[previous_points count]];
    self.trip_arrayOfAllPointsEDITED = [previous_points mutableCopy];
    //[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];

    self.trip_isArrayOfAllPointsEDITED = YES;
}

但删除一行后,它不会在当前单元格上提交消除“DELETE”标签的动画。有没有办法围绕“Apple方式”删除行?

编辑 - 我已经解决了

这很简单明了。只需将deleteRowsAtIndexPaths替换为:

    [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];

此“删除”动画消失后,单元格仍在其中。

你的意思是“删除”按钮会保留,即使你按下了它?在我的iOS 5.1模拟器之后 按“删除”键为空:

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

“删除”按钮消失。

我正在使用此代码并且工作正常

//self.selectedMessageIndex is NSIndexPath object declared in header file
//self.attachments is a NSMutableArray Object

[self.attachments removeObjectAtIndex:self.selectedMessageIndex.row];

[tblvAttachmentsList deleteRowsAtIndexPaths:[NSArray arrayWithObject:self.selectedMessageIndex]
                                  withRowAnimation:UITableViewRowAnimationLeft];
[tblvAttachmentsList reloadData];

self.tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation:.Automatic)

这将删除带有漂亮动画的删除按钮。当您知道不打算删除该行时调用:

func tableView(tableView: UITableView, commitEditingStyle editingStyle:UITableViewCellEditingStyle, forRowAtIndexPath indexPath:NSIndexPath) {
    if (editingStyle == UITableViewCellEditingStyle.Delete) {

        //An action happens here. If it was successful, page is refreshed
        //If the action fails, cell stays. I am showing an error and:
        self.tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation:.Automatic)
    }
}
