admob sdk - block certain types of ads or prevent embedded web view

[crestronfanatic]

Is there a way to block certain types of ads with admob? ie, @"url", @"app", etc... just like in the test mode? i only want to show app store apps, no websites or movies or anything else.

if not, is there at least a way to prevent ads from opening in the embedded web view? i tried setting useEmbeddedWebView to NO, but it has a weird behavior. first opens a blank web view inside my app, then closes the app and opens the ad in safari or the app store, finally when i go back into my app, the blank web view is still open.

- (BOOL)useEmbeddedWebView
{
return NO;
}

thanks for the help.
