Usually, iOS developers were passed by well designed UIs. To make the view fixed the design, we usually  set the background of some component as transparents. Some days ago , I faced a problem to set the background of UITableView, however, I tried long time to make the UITableView with the same background as the parent view.

At the beginning, I set the background color of the table view with clear color, but it didnt work.

[tView setBackgroundColor:[UIColor clearColor]];

Finally, I found that there is a default background view in the table view, so I set it nil in the viewDidLoad function, then it worked.

[tView setBackgroundView:nil];

UIImageView *cellBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"img_tablecell_bg.png"]];
[cell setBackgroundView:cellBackgroundView];</pre>
[cell setBackgroundColor:[UIColor clearColor]];
