UITableView backgroundColor always white on iPad

Question

I\'m working on a project. I have plenty of UITableViews which are set as clear color. Their views\' background color are set to my custom color and everything

Answer 1

You can fix this by making an appearance API setting in your appDelegate file :

Swift:

UITableViewCell.appearance().backgroundColor = UIColor.clearColor()

Answer 2

This solve this issue for me

 func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    tableView.backgroundColor = UIColor.clear
}

Answer 3

SWIFT

This was a happening to me, too. My table view in my SWRevealViewController appeared white on my iPad when it looked clear (which is how I wanted it with a background image) on my iPhone. I tried all of the above but this is what ended up working for me in my viewDidLoad().

tableView.backgroundView = UIImageView(image: UIImage(named: "gray"))
tableView.backgroundView?.backgroundColor = .clearColor()
UITableViewCell.appearance().backgroundColor = .clearColor()

Answer 4

Swift 3.1

I've worked around this bug by placing this in my UITableViewCell subclass:

When the cell is being loaded from the NIB file:

override func awakeFromNib() {
    super.awakeFromNib()
    self.backgroundColor = UIColor.clear
}

and when the cell is being reused by the system

override func prepareForReuse() {
    super.prepareForReuse()
    self.backgroundColor = UIColor.clear
}

iOS 10 is supposed to fix this issue in Interface Builder, as animeshporwal said.

Answer 5

I have a transparent table view with semi-transparent table view cells. I set the table view background color to clear when I create the table. This works for all iOS/device combinations except iPad + iOS 8, where the background color remains white.

For me, setting the cell's background color to semi-transparent and the content view background color to clear works, since I do it on each tableView(_ tableView: UITableView, cellForRowAt indexPath). The problem for me was only that the table view background remained white.

I tried all combinations that I did find regarding this issue, but the only thing I actually needed to to was to set the table views background to transparent on each tableView(_ tableView: UITableView, cellForRowAt indexPath). Not super-intuitive, but at least it works. :P

Answer 6

In my experience, some versions of iOS set UITableViewCell's backgroundColor before calling the delegate's tableView:willDisplayCell:forRowAtIndexPath:. Resetting back to your custom color in that method fixes it.
