Persistant white background though I have set it to clear
===

I've got a GridViewCell and am setting the background of it to clearColor like so:

    UIView* mainView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 123)];
    [mainView setBackgroundColor:[UIColor clearColor]];

Though for some reason, the background remains white.

If it's any help, I'm following [this tutorial][1].
