希望您至少获得了复选标记按钮。您可以使用以下代码在UITableViewCell中切换按钮的图像。它对我有用。对于表格视图单元格，我猜你也必须得到索引路径。

- (void)selectDistance: (UIButton *)button event:(UIEvent *)event{
    NSIndexPath* indexPath = [self.table indexPathForRowAtPoint:
                              [[[event touchesForView:button] anyObject]
                               locationInView:self.table]];
    if (button.selected) {
        [button setBackgroundImage:[UIImage imageNamed:@"checkboxoff-5.png"] forState:UIControlStateNormal];
        [button setSelected:NO];
    }else{
        [button setBackgroundImage:[UIImage imageNamed:@"checkboxon-5.png"] forState:UIControlStateNormal];
        [button setSelected:YES];
 }
