UITableView clear background - ios

Question

I realize that iOS 7 has not officially been released and we should not discuss it BUT I am going crazy trying to figure out this problem. On iOS 6, my table view was transparent and looked great. First time running iOS 7, and the background is white.
I have tried making the table backgroundColor, cell color etc etc to UIColor clearColor but have no change.
How to fix this problem?

Answer 1

// Fix for iOS 7 to clear backgroundColor
cell.backgroundColor = [UIColor clearColor];
cell.backgroundView = [[UIView new] autorelease];
cell.selectedBackgroundView = [[UIView new] autorelease];
in cellForRowAtIndexPath
Also, make sure that your tableview actually has transparent background (in storyboard):

Answer 2

Put this:
cell.backgroundColor = [UIColor clearColor];
In this section:
cellForRowAtIndexPath

Answer 3

Try setting backgroundView to nil first.
[self.tableView setBackgroundView:nil];
[self.tableView setBackgroundColor:[UIColor clearColor]];
Not sure if this is a change in documentation with iOS7 or has always been there and just did not affect background color, but per UITableView Class Reference #property backgroundView
"You must set this property to nil to set the background color of the table view."
edit: corrected code syntax

Answer 4

This has been answered, but incorrectly in a lot of ways.
You need to implement the below delegate method:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
[cell setBackgroundColor:[UIColor clearColor]];
}
You can't put the fix in cellForRowAtIndexPath because that is after the cell is rendered, and it will flash a white background before the background gets set to clear (on slower devices).
Use this delegate method and your problems are solved!

Answer 5

Actually the officially correct place to change cell background color is different according to documentation (UITableViewCell Class Reference):
Whether you use a predefined or custom cell, you can change the cell’s
background using the backgroundView property or by changing the
inherited backgroundColor property. 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.

Answer 6

swift 3, 4 and 5
cell.backgroundColor = UIColor.clear

Answer 7

This is quite a frustrating problem. Here's my current solution:
Add this to your UITableViewCell subclass.
- (void)didMoveToSuperview {
[super didMoveToSuperview];
self.backgroundColor = [UIColor clearColor];
}

Answer 8

This did only work for me when i edited a clear background color for each cell and a clear color for the table itself.. BOTH PROGRAMMATICALLY
to set the clear color for the table:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
initMenu()
myTableView.backgroundColor = UIColor.clearColor()
}
to set the color for the cells:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("tablecellid", forIndexPath: indexPath)
cell.backgroundColor = UIColor.clearColor()
return cell
}

Answer 9

This worked for me in iOS7+:
self.tableView.backgroundColor =[UIColor blueColor];
self.tableView.opaque = NO;
self.tableView.backgroundView = nil;`
and then in cellForRowAtIndexPath:
cell.backgroundColor = [UIColor clearColor];

Answer 10

try this code snippet
cell.contentView.backgroundColor = [UIColor clearColor];
cell.backgroundColor = [UIColor colorWithWhite:1.0 alpha:0.5];

Answer 11

First set
tableView.backgroundColor = [UIColor clearColor];
Second set
tableCell.backgroundColor = [UIColor clearColor];

Answer 12

One thing to nice. The default color of UITable seems to be white (I don't know why)
But better change that.

Answer 13

create IB Outlet for table view
#IBOutlet weak var yourTable : UITableView!
in view load
override func viewDidLoad() {
yourTable.delegate = self
yourTable.dataSource = self
yourTable.backgroundColor = UIColor.clearColor()
}
if you want to clear color of Cell also do this in
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
cell.backgroundColor = UIColor.clearColor()
}

Answer 14

In my app, I had to set the backgroundColor on my UITableViewCell class to [UIColor clearColor] color when I updated for iOS 7.

Answer 15

Try
[myTable setSeparatorStyle:UITableViewCellSeparatorStyleNone];
[myTable setSeparatorInset:UIEdgeInsetsZero];
And
cell.backgroundColor = [UIColor clearColor];

Answer 16

In my case the cell was created using a xib. it seems like interface builder on xcode5 has trouble setting clearColor to the cell.backgroundColor.
All I needed to do was indeed to set
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// get the cell from the nib
//then force the backgroundColor
cell.backgroundColor = [UIColor clearColor]
return cell;
}

Answer 17

Just select Clear Color on View Background for the table and for the cell also.

Answer 18

swift 3
override func viewDidLoad() {
super.viewDidLoad()
tableView.backgroundColor = UIColor.clear
}

Answer 19

// Fix iOS 7 clear backgroundColor compatibility
// I Think this two lines only are enough
cell.backgroundColor = [UIColor clearColor];
cell.selectedBackgroundView = [[UIView new] autorelease];

Answer 20

In swift 3
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath)
cell.backgroundColor = .clear
cell.backgroundView = UIView()
cell.selectedBackgroundView = UIView()
return cell
}

Answer 21

Set
tableView.backgroundColor = [UIColor clearColor];
in viewDidLoad.
if this is not working, try:
tableView.backgroundView = nil;
