How to make a UITableView as transparent one?

In my application, i am presenting an UITableViewController class (Grouped 开发者_运维技巧style) to the user for the particular scenario. I want to show the table view's cells only. The background should be transparent so that the user can see the previous page.

I tried with the following codes in viewDidLoad method of the table view controller. But they are not working..

self.tableView.backgroundColor = [UIColor clearColor];

self.tableView.opaque = NO;

self.tableView.backgroundView = nil;

Is it possible to show the cells with a dimmed background?

Thanks in Advance

I use: (in viewDidLoad)

   self.tableView.backgroundColor = [UIColor clearColor];
    self.tableView.opaque = NO;

Then in cellForRowAtIndexPath:

cell.textLabel.backgroundColor = [UIColor clearColor];
    cell.detailTextLabel.backgroundColor = [UIColor clearColor];
    cell.backgroundColor = [UIColor colorWithWhite:1 alpha:.55];

Not sure if this is what you wanted, but it gives you the option to make everything clear. (obviously the alpha would change for your case, but that measures theo pacity of the cells)

Just altering the tableView doesn't help. You have to mess with the cells also. Inside the cellForRowAtIndexPath:(NSIndexPath *)indexPath method, put this before the return statement:

UIView * bgView =[[UIView alloc] initWithFrame:CGRectZero] autorelease];
bgView.backgroundColor = [UIColor clearColor];
cell.backgroundView = bgView;
