Why can't I place a UIActivityIndicatorView on a UITableView by using Interface Builder?
<p>I can place a UIActivityIndicatorView on a UIWindow or a UIView by using Interface Builder like as follows.<br>

But I can't place a UIActivityIndicatorView on a UITableView by using Interface Builder.<br>
What's the reason? Are there any ways?<br>
I can place it on a UITableView programmatically.<br>
