Cannot change background color of UITableViewCell

Question

I have UITableViewCellone that is suitable for UITableView, but somehow I can’t change the background color when I enter the edit style mode. I tried everything on the Internet, searched all day, but still couldn't fix it (I searched StackOverflow as well). Please help me.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    MainTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {

        NSArray* views = [[NSBundle mainBundle] loadNibNamed:@"MainTableViewCell" owner:nil options:nil];

        for (UIView *view in views) {
            if([view isKindOfClass:[UITableViewCell class]])
            {
                cell = (MainTableViewCell *)view;
            }
        }
    }

Answer 1

Try setting the cell inside the method tableView: willDisplayCell:, something like this:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {

    cell.backgroundColor = [UIColor redColor];

}

Answer 2

You need to change the tableView cellView element, not the cell view.

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {

    cell.contentView.backgroundColor = [UIColor redColor];
}

Answer 7

Make sure you have not set the background color of the content view in the storyboard. If you do, changing the cell.backgroundColor in the code will not make any difference, and you will get confused in the round (like me).

Answer 8

 cell.backgroundColor = [UIColor redColor];

Answer 9

in swift 3 you can use

cell.backgroundcolor = UIColor.white
