Answer 1

Best Approach

Simple.Before show up the UITable View add one more grayed out/Transparent view then add tap gesture recogniser on it to hide it . That's it.

1. Show Overlay View first - alpha will be 0.5f and background color should be clear color.

2. show the table view.

NOTE: over lay view should have tap recogniser which will hide the overlay and table view

in View did load

UITapGestureRecognizer *tapRecog = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                action:@selector(overlayDidTap:)];

[myOverLayView addGestureRecognizer:tapRecog];



- (void)overlayDidTap:(UITapGestureRecognizer *)gesture
{

    //hide both overlay and table view here

}

Bad Approach

We should not add tap recogniser on main view itself. Because it may have lots of controls inside of it. so when user tap on it. it will perform its operation. So to avoid it we can simulate the same behaviour by above approach
