How to customize the background color of a UITableViewCell?

Answers

1.

You need to set the backgroundColor of the cell's contentView to your color. If you use accessories (such as disclosure arrows, etc), they'll show up as white, so you may need to roll custom versions of those.

Here is the most efficient way I have come across to solve this problem, use the willDisplayCell delegate method (this takes care of the white color for the text label background as well when using cell.textLabel.text and/or cell.detailTextLabel.text):

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

When this delegate method is called the color of the cell is controlled via the cell rather than the table view, as when you use:

- (UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath { ... }

So within the body of the cell delegate method add the following code to alternate colors of cells or just use the function call to make all the cells of the table the same color.

if (indexPath.row % 2){    [cell setBackgroundColor:[UIColor colorWithRed:.8 green:.8 blue:1 alpha:1]];}else [cell setBackgroundColor:[UIColor clearColor]];

This solution worked well in my circumstance...

This is really simple, since OS 3.0 just set the background color of the cell in the willDisplayCell method. You must not set the color in the cellForRowAtIndexPath.

This works for both the plain and grouped style :

Code:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {    cell.backgroundColor = [UIColor redColor];}

P.S: Here the documentation extract for willDisplayCell :

"A table view sends this message to its delegate just before it uses cell to draw a row, thereby permitting the delegate to customize the cell object before it is displayed. This method gives the delegate a chance to override state-based properties set earlier by the table view, such as selection and background color. After the delegate returns, the table view sets only the alpha and frame properties, and then only when animating rows as they slide in or out."

The best approach I've found so far is to set a background view of the cell and clear background of cell subviews. Of course, this looks nice on tables with indexed style only, no matter with or without accessories.

Here is a sample where cell's background is panted yellow:

UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ];backgroundView.backgroundColor = [ UIColor yellowColor ];cell.backgroundView = backgroundView;for ( UIView* view in cell.contentView.subviews ) {    view.backgroundColor = [ UIColor clearColor ];}

Simply put this in you UITableView delegate class file (.m):

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {  UIColor *color = ((indexPath.row % 2) == 0) ? [UIColor colorWithRed:255.0/255 green:255.0/255 blue:145.0/255 alpha:1] : [UIColor clearColor];  cell.backgroundColor = color;}

Enjoy!

I concur with Seba, I tried to set my alternating row color in the rowForIndexPath delegate method but was getting inconsistent results between 3.2 and 4.2. The following worked great for me.

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {    if ((indexPath.row % 2) == 1) {        cell.backgroundColor = UIColorFromRGB(0xEDEDED);        cell.textLabel.backgroundColor = UIColorFromRGB(0xEDEDED);        cell.selectionStyle = UITableViewCellSelectionStyleGray;    }    else    {        cell.backgroundColor = [UIColor whiteColor];        cell.selectionStyle = UITableViewCellSelectionStyleGray;    }}

Create an image to use as background with photoshop or gimp and name it myimage Then add this method to your tableViewController class

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {UIImage *cellImage = [UIImage imageNamed:@"myimage.png"];//myimage is a 20x50 px with  gradient  color created with gimpUIImageView *cellView = [[UIImageView alloc] initWithImage:cellImage];cellView.contentMode = UIContentViewModeScaleToFill;cell.backgroundView = cellView;//set the background label to clearcell.titleLabel.backgroundColor= [UIColor clearColor];}

This will work also if you have set the UITableView to custom in attribute inspector

After trying out all different solutions, the following method is the most elegant one. Change the color in the following delegate method:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {    if (...){        cell.backgroundColor = [UIColor blueColor];    } else {        cell.backgroundColor = [UIColor whiteColor];    }}
