UITableView transparent background

Question

I understand that iOS 7 has not been officially released, and we should not discuss it, but I'm going crazy trying to figure this out. On iOS 6, my table view was transparent and looked great. The first launch of iOS 7, and the background is white.

I tried to make table backgroundColor, cell color, etc. for UIColor clearColor, but has no changes.

How to solve 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 your desk has a transparent background (in the storyboard):

Answer 2

Put this:

 cell.backgroundColor = [UIColor clearColor]; 

In this section:

 cellForRowAtIndexPath 

Answer 3

This is the answer, but wrong in many ways.

You need to implement the following delegate method:

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

You cannot put the patch in cellForRowAtIndexPath because it is after the cell is displayed and it will flash a white background before the background is cleared (on slower devices).

Use this delegate method and your problems are resolved!

Answer 4

Try setting backgroundView to zero first.

 [self.tableView setBackgroundView:nil]; [self.tableView setBackgroundColor:[UIColor clearColor]]; 

Not sure if this documentation change with iOS7 either always has and just hasn’t affected the background color, but the UITableView Reference Reference @property backgroundView

"You must set this property to zero to set the background color as a table."

edit: fixed code syntax

Answer 5

Actually, the officially correct place for changing the background color of a cell differs according to the documentation ( UITableViewCell Class Reference ):

If you use a predefined or custom cell, you can change the cells using the backgroundView property or by changing the inherited backgroundColor property. In iOS 7, cells have a white background color by default; in earlier versions of iOS, cells inherit the background color in the form of a table. If you want to change the background color of the cell, do it in tableView: willDisplayCell: forRowAtIndexPath: delegate the table view method.

Answer 6

This is a pretty nasty problem. Here is my current solution:

Add this to your subclass of UITableViewCell .

 - (void)didMoveToSuperview { [super didMoveToSuperview]; self.backgroundColor = [UIColor clearColor]; } 

Answer 7

This worked for me on iOS7 +:

 self.tableView.backgroundColor =[UIColor blueColor]; self.tableView.opaque = NO; self.tableView.backgroundView = nil;` 

and then in cellForRowAtIndexPath:

 cell.backgroundColor = [UIColor clearColor]; 

Answer 8

Swift 3, 4, and 5

 cell.backgroundColor = UIColor.clear 

Answer 9

try this piece of code

 cell.contentView.backgroundColor = [UIColor clearColor]; cell.backgroundColor = [UIColor colorWithWhite:1.0 alpha:0.5]; 

Answer 10

This only worked for me when I edited a clear background color for each cell and a clear color for the table itself. PROGRAMMED

To set a 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() } 

set color for cells:

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCellWithIdentifier("tablecellid", forIndexPath: indexPath) cell.backgroundColor = UIColor.clearColor() return cell } 

Answer 11

One thing is good. UITable color looks white by default (I don't know why)

But better change that.

Answer 12

First set

 tableView.backgroundColor = [UIColor clearColor]; 

Second set

 tableCell.backgroundColor = [UIColor clearColor]; 

Answer 13

create IB Outlet to view the @IBOutlet table weak var yourTable: UITableView!

in the load view

 override func viewDidLoad() { yourTable.delegate = self yourTable.dataSource = self yourTable.backgroundColor = UIColor.clearColor() } 

if you want to clear the cell color do it in

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { cell.backgroundColor = UIColor.clearColor() } 

Answer 14

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

Answer 15

In my case, the cell was created using xib. it looks like the interface builder on xcode5 has problems setting clearColor on cell.backgroundColor.

All I had to do was install

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // get the cell from the nib //then force the backgroundColor cell.backgroundColor = [UIColor clearColor] return cell; } 

Answer 16

Try

 [myTable setSeparatorStyle:UITableViewCellSeparatorStyleNone]; [myTable setSeparatorInset:UIEdgeInsetsZero]; 

and

 cell.backgroundColor = [UIColor clearColor]; 

Answer 17

Just select "Clear Color" in the "Background" view for the table and for the cell.

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

Set

 tableView.backgroundColor = [UIColor clearColor]; 

in viewDidLoad.

If this does not work, try:

 tableView.backgroundView = nil; 

Answer 21

In fast 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 }
