Say the icons are stored as icon0.png, icon1.png and so on in the app bundle. You can give the icon for each cell as
假设图标在应用程序包中存储为 icon0.png、icon1.png 等。您可以将每个单元格的图标指定为
cell.imageView.image = [UIImage imageNamed:
[NSString stringWithFormat:@"icon%d.png",indexPath.row]];
Swift
迅速
cell.imageView?.image = UIImage(named: "icon\(indexPath.row).png")

Well, you have an array somewhere to return the correct number in numberOfRowsInSection. That array is the one you use to fill up the cells. If you only want to display icons in your cells, your array of icons is like that.
好吧，您在某处有一个数组可以在numberOfRowsInSection. 该数组是您用来填充单元格的数组。如果您只想在单元格中显示图标，那么您的图标数组就是这样。
So, for example:
因此，例如：
UIImage *one = ...;
UIImage *two = ...;
[arrayIcons addObject: one];
[arrayIcons addObject: two];
and in numberOfRowsInSection, return [arrayIcons count].
并在 numberOfRowsInSection 中返回[arrayIcons count]。
In the method cellForRowAtIndexPath, you have the variable indexPath. If you want to know which cell you have, you use: indexPath.row.
在方法中cellForRowAtIndexPath，您有变量indexPath。如果您想知道您拥有哪个单元格，请使用：indexPath.row。
So, if you load the cell (probably custom, see other answers), which has a UIImageView(say it's named: imageView), and you load the icons in the cells like this:
因此，如果您加载单元格（可能是自定义的，请参阅其他答案），它有一个UIImageView（比如它的名称：imageView），并且您在单元格中加载图标，如下所示：
cell.imageView = [UIImage imageWithContentsOfFile:[arrayIcons objectAtIndex:indexPath.row]];
