我有四个不同的单元格，我试图向其中添加图像，每次更改图像时，它都会将图像添加到每个单元格中。我正在尝试为每个单元格添加单独的图像，但我不知道该怎么做。任何帮助都会很棒！这是我的代码：

if ([singletonObj.tempChangelistColor isEqualToString:@"red"]) {

            self.layer.contents = (id)[UIImage imageNamed:@"red.png"].CGImage;

        }else if([singletonObj.tempChangelistColor isEqualToString:@"yellow"]){

          self.layer.contents = (id)[UIImage imageNamed:@"yellow.png"].CGImage;

        }else if([singletonObj.tempChangelistColor isEqualToString:@"green"]){

            self.layer.contents = (id)[UIImage imageNamed:@"green.png"].CGImage;
        }else{

            self.layer.contents = (id)[UIImage imageNamed:@"shop_deal.png"].CGImage;

        }

它位于shop_deal.png的代码底部。

如果您确切知道手机号码。您想要更改图像，那么这将对您有所帮助。

NSIndexPath *cellIndex = [NSIndexPath indexPathForRow:3 inSection:0]; // suppose cell no is 3 in section 0
UITableViewCell *cell = [_youtTableView cellForRowAtIndexPath:cellIndex];

cell.imageView.image = [UIImage imageNamed:@"shop_deal.png"];

希望这可以帮助。
