选择单元格时更改图像

Question

在我的应用程序中,我在左侧有一个UITableView作为菜单.当我按下表格的单元格时,右侧的视图会发生变化.我的"菜单"表有海关单元格,我想在选择此单元格时更改单元格的图像.我怎样才能做到这一点？

码:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"MenuCell";
    CRMMenuCell *cell = (CRMMenuCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (!cell){

        NSArray * topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CRMMenuCell" owner:nil options:nil];

        for (id currentObjetc in topLevelObjects){

            if ([currentObjetc isKindOfClass:[CRMMenuCell class]]){

                cell = (CRMMenuCell *)currentObjetc;
                break;
            }

        }

    }



    cell.selectionStyle = UITableViewCellSelectionStyleNone;


    if (indexPath.row == 0)
    {
        cell.labelMenu.text = NSLocalizedString(@"calendarioKey", @"");
        cell.imagenMenu.image = [UIImage imageNamed:@"calendario_gris"];

    }





- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *cellIdentifier = @"MenuCell";
    CRMMenuCell *cell = (CRMMenuCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];


    if (!cell){

        NSArray * topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CRMMenuCell" owner:nil options:nil];

        for (id currentObjetc in topLevelObjects){

            if ([currentObjetc isKindOfClass:[CRMMenuCell class]]){

                cell = (CRMMenuCell *)currentObjetc;
                break;
            }

        }

    }


    if (indexPath.row == 0) 
    {

        cell.imagenMenu.image = [UIImage imageNamed:@"calendario_rojo"];


    }

谢谢.

你可以这样做

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

您的TableView的委托.

如何更改图像取决于您的实现,但它应该是这样的:

CRMMenuCell *cell = (CRMMenuCell*)[tableView cellForRowAtIndexPath:indexPath];
cell.myImage = newImage;

编辑:尝试以下内容:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   CRMMenuCell *cell = (CRMMenuCell*)[tableView cellForRowAtIndexPath:indexPath];
   cell.imagenMenu.image = [UIImage imageNamed:@"calendario_gris"];
}
