ios - 如何移动 uitableview 自定义单元格？

Question

我使用自定义单元格。我想移动这个单元格(改变单元格的位置)

我使用了这个委托(delegate)

UITableViewDataSource,UITableViewDelegate

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

static NSString *Cellidentifier = @"Celledit";
CellEdit *editCell =[tableView dequeueReusableCellWithIdentifier:Cellidentifier];

if (!editCell) {
    editCell = [[CellEdit alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:Cellidentifier];
}

MItem *mItem = [mItems objectAtIndex:[indexPath row]];


 ---------------------------------
 // set data 3 labales in the cell
 --------------------------------- 

editCell.editdelegate = self;
return editCell;

editcell 是我的自定义单元格

[_tableViewEdit setEditing:YES animated:YES]; 这一行放在 - (void)viewDidLoad

我想一直编辑它

    // table view change cells
- (UITableViewCellEditingStyle) tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewCellEditingStyleNone;
}

- (BOOL) tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}

- (void) tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath {

    NSInteger sourceRow = sourceIndexPath.row;
    NSInteger destRow = destinationIndexPath.row;
    id object = [minutesItems objectAtIndex:sourceRow];

    [minutesItems removeObjectAtIndex:sourceRow];
    [minutesItems insertObject:object atIndex:destRow];

}

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
    for (UIControl *control in cell.subviews)
    {
        if ([control isMemberOfClass:NSClassFromString(@"UITableViewCellReorderControl")] && [control.subviews count] > 0)
        {
            for (UIControl *someObj in control.subviews)
            {
                if ([someObj isMemberOfClass:[UIImageView class]])
                {
                    UIImage *img = [UIImage imageNamed:@"logocoffee.png"];
                    ((UIImageView*)someObj).frame = CGRectMake(0.0, 0.0, 43.0, 43.0);
                    ((UIImageView*)someObj).image = img;
                }
            }
        }
    }
}


}

移动单元格模拟器不显示右侧控制图标

这是为什么？这意味着不能移动服装细胞？

试试这段代码，

你应该使用下面两种方法，

- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

使用此方法移动行

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath 
{
   [label1array exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
    [label2array exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
    [label3array exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
}
