Uitableviewcell Show White Background and Cannot Be Modified on iOS7

UITableViewCell show white background and cannot be modified on iOS7

As Apple DOC said (UITableViewCell Class Reference):

... In iOS 7, cells have a white background by default; in earlier versions of iOS, cells inherit the background color of the enclosing table view. If you want to change the background color of a cell, do so in the tableView:willDisplayCell:forRowAtIndexPath: method of your table view delegate.

So for my case that to show cells with transparent background, just need to implement the delegate method in the table view controller like below:

- (void)tableView:(UITableView *)tableView
  willDisplayCell:(UITableViewCell *)cell
forRowAtIndexPath:(NSIndexPath *)indexPath
{
  [cell setBackgroundColor:[UIColor clearColor]];
}

Just Note: As @null said, "...there seems to be a bug in interface builder...", I'm not totally sure whether it does have the bug, but seems so cause his comment got several up votes. So there might something wrong if you use IB. :)

UITableView / UITableViewCell challenge with transparent background on iPad with iOS7

After wasting multiple hours with interface builder, I'm thinking that there might be a bug there. So I started to look for a programatic answer. Apparently had I started here I could have saved a ton of time. By adding to the method:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

I was able to solve the transparency issue on iPad by adding this one line:

cell.backgroundColor = [UIColor clearColor];  // Adding this fixes the issue for iPad

Hope this helps everyone else with the white background seen for ipad with tables and iOS7!

White background is showing above UISearchBar for iOS7

I managed to get rid of that color by setting a table view background view.

UIView *backgroundView = [[UIView alloc] initWithFrame:self.tableView.bounds];
backgroundView.backgroundColor = [UIColor clearColor];
self.tableView.backgroundView = backgroundView;

Programmatically created UITableView always white in iOS9

init method is not a good place to modify UI properties because the view hierarchy hasn't been constructed yet.

Try using layoutSubviews or didMoveToWindow for UIView subclasses:

var customColor = UIColor.yellowColor()
override func layoutSubviews() {
    super.layoutSubviews()
    self.backgroundColor = customColor
}

override func didMoveToWindow() {
    super.didMoveToWindow()
    self.backgroundColor = customColor
}

You can also use viewDidLoad or awakeFromNib methods in UIViewController subclasses:

override func viewDidLoad() {
    super.viewDidLoad()
    customTableView.backgroundColor = UIColor.yellowColor()
}

override func awakeFromNib() {
    super.awakeFromNib()
    customTableView.backgroundColor = UIColor.yellowColor()
}

UITableView checkmark has a white background

Instead of accessoryview you can use imageview to show Checked record.

UITableView with custom cells draws fine on iOS 6 but completely white in iOS 7

Can't set background color of UITableViewCell in IB

There's an easier solution: When you create a UITableViewCell in Interface Builder, simply drag and drop an additional UIView so that it covers the entire UITableViewCell you're creating within IB. Place your additional UI elements on top of this additional UIView. You can set this extra UIView to whatever background you like.

There are quite a few answers on StackOverflow that suggest you change the background color of your UITableViewCell by using a line of code like this one:

cell.contentView.backgroundColor = [UIColor redColor];

If you add a drop shadow to your cell by adjusting the contentView's frame size slightly, you may find that this line will change both the background color of your cell and the color of your drop shadow area as well.
