How to set background color of tableView

Question

I have tried all the way but could not succeed to set backgroundColor of TableView. setting tableView.backgroundColor and/or cell.backgroundColor to clearColor didn't work when the parent view controller was UIViewContoller.

My nib file structure is

FileOwner
View
UITableView

(Note: i set the TableView to groupedTable section)

First attempt, I created the UIView in the code viewDidLoad

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 300)] autorelease;
[view setBackgroundColor:UIColor blueColor]; // color it just to see if it is created at the right place
[self.tableView sendSubViewToBack:view];

It works but it hides the content of cell. I am able to see the content of header but not cell content. (But when i change the co-ordinate of view(0,150,160,300) then i am able to see the cell's content but then it loose the backgroundColor of tableview.

Second attempt, I created the imageView

View
ImageView
UITableView

and set the self.tableView.backgroundColor = [UIColor clearColor]; but did not work.

I googled but did not the peaceful answer.

Answer 1

A UITableView with the grouped style uses a background view. To get rid of the background view and let the background color show, try either of the following:

tableView.backgroundView = nil;
tableView.backgroundView = [[[UIView alloc] init] autorelease];

After that, you should be able to set the background color normally:

tableView.backgroundColor = [UIColor redColor];

BTW, only a view can be the parent/superview of another view, and a view controller is not a view.

Answer 2

This has always worked for me:

UITableView *tableView = [[UITableView alloc] initWithFrame:tableFrame style:UITableViewStylePlain];
tableView.backgroundColor = [UIColor redColor];
[parentView addSubview:tableView];

Make sure that the tableView is not nil, not hidden, has the correct frame, and that it has been added to the correct parent view.
