Transparent background in grouped UITableView - iPhone

Question

I want to make the grouped UITableView transparent. I partially succeded with the following code:

UIColor *bgColor = [[UIColor alloc] initWithWhite:1 alpha:0         


        

Answer 1

remove UITableView backgroundView

xxx.backgroundView = nil;

This is necessary on iPad builds. When compiling to run on iPad and iPhone, check the tableView responds to the selector with ...

if ([self.tableView respondsToSelector:@selector(setBackgroundView:)]) {
    [self.tableView setBackgroundView:nil];
}
