Google Mobile Ads SDK 6.10.0: <Google> Must set the rootViewController property of GADBannerView before calling loadRequest

问题

This error just started showing up following upgrade to 6.10.0, so a different issue to the other questions reporting this same issue. I've walked through the code and setting the Root View Controller of the GADBannerView doesn't take effect:

    [self.adUnit setRootViewController:controller];
    NSLog(@"Ad Unit:          %@", [self.adUnit class]);
    NSLog(@"Root VC:          %@", [controller class]);
    NSLog(@"Ad Unit Root VC:  %@", [self.adUnit.rootViewController class]);

Results in:

2014-07-25 11:52:23.234 *** [16665:607] Ad Unit:          GADBannerView
2014-07-25 11:52:23.235 *** [16665:607] Root VC:          MyAppViewController
2014-07-25 11:52:23.235 *** [16665:607] Ad Unit Root VC:  (null)

Heard from Google:

"I checked with the engineers who said this is fixed at our head revision. They're still investigating why it happened in the first place though.

I don't have a date yet for when we'll be doing another release, so in the short term I'd recommend rolling back to 6.9 to address your immediate issue."
