设置UITableViewCell附件背景的自定义颜色

Question

I'm trying to get my table view cells to show a custom checkmark image when selected. The issue is that the color behind the checkmark image is gray instead of the custom cell color that I provide.

I'm aware this question has been asked before - I've read through and attempted to the following suggestions:

• Wrong Background Color in Accessory View on iOS7
• How to get Transparent Accessory View in UITableViewCell? (w/ Screenshot)
• Altering the background color of cell.accessoryView and cell.editingAccessoryView

Among others. The general consensus seems to that changing the color of the cell's backgroundView will affect the accessory, but this does not seem to be the case for me. Here is my current code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryView = [[UIImageView alloc] initWithImage:_checkImage];

    [self setCellColor:_customColor forCell:cell];
}

- (void)setCellColor:(UIColor *)color forCell:(UITableViewCell *)cell
{
    cell.contentView.backgroundColor = color;
    cell.backgroundView.backgroundColor = color;
    cell.backgroundColor = color;
 }

Note that my checkImage has a transparent background. Upon selecting a cell, the background of my cell changes to my customColor , but the background on the accessory remains gray. SOS!

That is correct. The problem is that you are not doing that. You are saying this:

cell.backgroundView.backgroundColor = color;

But cell.backgroundView is nil, so that line is pointless. You need to give your cell a background view before you can set the color of that view.
