ios – 如何切换UITableView Cell选择状态

我有一个带有自定义Cell的UITableView,该单元格包含一个UI ImageView和一个UILabel.现在当我第一次加载我的表时,它会在每个单元格和不同的标签上加载相同的图像,它从LabelArray中获取.

现在我说的图像是radioButton,所以当用户点击单元格时,图像会发生变化.如果用户再次单击,则会更改为默认状态.

为此,我使用了这个函数,并且我在customcell类中声明了一个名为selectionStatus的bool变量.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    CustomCell * cell = (CustomCell* )[tableView cellForRowAtIndexPath:indexPath];

    if(indexPath.row == 0)
    {
        if(cell.selectionStatus == TRUE)
        {           
            //Do your stuff
           cell.selectionStatus = FALSE;
        }
        else
        {
            //Do your stuff
            cell.selectionStatus = TRUE;
        }
    }

    if(indexPath.row == 1)
    {
        if(cell.selectionStatus == TRUE)
        {           
            //Do your stuff
           cell.selectionStatus = FALSE;
        }
        else
        {
            //Do your stuff
            cell.selectionStatus = TRUE;
        }
    }
}

这很好,(但我想知道它是否是一种正确的方法,或者我们可以检查cell.selected属性),我能够得到这种效果.但现在当我关闭View并再次打开它的功能时

使用@Anil根据以下评论进行编辑

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

    if([self.checkedIndexpath count]  == 0)
    {
        [tableCell.selectionImage setImage:@"xyz.png"];
    }
    else
    {        
        for (int i =0; i <[self.checkedIndexPath count]; i++)
        {
            NSIndexPath *path = [self.checkedIndexPath objectAtIndex:i];
            if ([path isEqual:indexPath])
            {               
                [tableCell.selectionImage setImage:@"abc.png"]
            }
            else
            {
                 [tableCell.selectionImage setImage:@"xyz.png"]            
             }
    }
return tableCell;

你必须在didSelectRowAtIndexPath中保存所选行的索引路径并检查cellForRowAtIndexPath中的索引路径：设置相应的图像

你想要多重选择吗？试试这个…

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
CustomCell * cell = (CustomCell* )[tableView cellForRowAtIndexPath:indexPath];

if(indexPath.row == 0)
{
    if(cell.selectionStatus == YES)
    {     
      [self.checkedIndexPaths addObject:indexPath];
        //Do your stuff
       cell.selectionStatus = NO;
    }
    else
    {
        [self.checkedIndexPaths removeObject:indexPath];
        //Do your stuff
        cell.selectionStatus = YES;
    }
}
}

编辑
在cellForIndexPath中检查如下

// Set the default image for the cell. imageXYZ   
for (NSIndexPath *path in self.checkedIndexPath) 
{
    if ([path  isEqual:indexPath])
    {
        //set the changed image for the cell. imageABC
    }
    // no need of else part
}

确实,我们会看到
