/* webkit-tap-highlight-color */
a:link { -webkit-tap-highlight-color: #aa0000; }

/* To set it to none use a totally transparent RGBA */

You can also check out the Safari Mobile developer docs to see the supported CSS properties.

Webkit has a specific style property for that: -webkit-tap-highlight-color.

Copied from: http://davidwalsh.name/mobile-highlight-color—

/* light blue at 80% opacity */
html {
    -webkit-tap-highlight-color: rgba(201, 224, 253, 0.8);
}

/* change it for a div that has a similar background-color to the light blue tap color */
.blueDiv {
    -webkit-tap-highlight-color: rgba(251, 185, 250, 0.9);
}

If you want to remove the highlight completely—

.myButton {
    -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}

Disabled UIButton not faded or grey

You can use following code:

sendButton.enabled = YES;
sendButton.alpha = 1.0;

or

sendButton.enabled = NO;
sendButton.alpha = 0.5;

As mentioned in iOS dark gray box active style you have to hide the tap highlight box:

img { -webkit-tap-highlight-color: rgba(0,0,0,0); }

How to change the colors of a segment in a UISegmentedControl in iOS 13?

As of iOS 13b3, there is now a selectedSegmentTintColor on UISegmentedControl.

To change the overall color of the segmented control use its backgroundColor.

To change the color of the selected segment use selectedSegmentTintColor.

To change the color/font of the unselected segment titles, use setTitleTextAttributes with a state of .normal/UIControlStateNormal.

To change the color/font of the selected segment titles, use setTitleTextAttributes with a state of .selected/UIControlStateSelected.

If you create a segmented control with images, if the images are created as template images, then the segmented control's tintColor will be used to color the images. But this has a problem. If you set the tintColor to the same color as selectedSegmentTintColor then the image won't be visible in the selected segment. If you set the tintColor to the same color as backgroundColor, then the images on the unselected segments won't be visible. This means your segmented control with images must use 3 different colors for everything to be visible. Or you can use non-template images and not set the tintColor.

Under iOS 12 or earlier, simply set the segmented control's tintColor or rely on the app's overall tint color.

UITableView - change section header color

Hopefully this method from the UITableViewDelegate protocol will get you started:

Objective-C:

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
  UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
  if (section == integerRepresentingYourSectionOfInterest)
     [headerView setBackgroundColor:[UIColor redColor]];
  else 
     [headerView setBackgroundColor:[UIColor clearColor]];
  return headerView;
}

Swift:

func tableView(_ tableView: UITableView!, viewForHeaderInSection section: Int) -> UIView!
{
  let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
  if (section == integerRepresentingYourSectionOfInterest) {
    headerView.backgroundColor = UIColor.redColor()
  } else {
    headerView.backgroundColor = UIColor.clearColor()
  }
  return headerView
}

Updated 2017:

Swift 3:

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
    {
        let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
        if (section == integerRepresentingYourSectionOfInterest) {
            headerView.backgroundColor = UIColor.red
        } else {
            headerView.backgroundColor = UIColor.clear
        }
        return headerView
    }

Replace [UIColor redColor] with whichever UIColor you would like. You may also wish to adjust the dimensions of headerView.
