Admob banner not filling up full screen - xcode

Question

My app was just released the other day. When I downloaded it to an iPhone 6 I noticed the admob banner didn't fill the full screen (look at the attached picture). The banner works fine on an iPad and iPhone 5 but isn't working correctly on the iPhone 6.
Here is my code I am using for the banner:
_bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
_bannerView_.frame = CGRectMake(0.0,
self.view.frame.size.height -
_bannerView_.frame.size.height,
_bannerView_.frame.size.width,
_bannerView_.frame.size.height);
_bannerView_.adUnitID = #"ID";
_bannerView_.rootViewController = self;
GADRequest *request = [GADRequest request];
[_bannerView_ loadRequest:request];
[self.view addSubview:_bannerView_];
Does anyone see any problems or know how to fix this problem? Thanks in advance

Answer 1

I used below code to create Admob Banner. It worked fine in iPhone6 also.
-(void)createBannerAds
{
//set up banner coordinates to display at the bottom
CGPoint origin = CGPointMake(0.0,self.view.frame.size.height -kGADAdSizeSmartBannerPortrait.size.height);
self.adBanner = [[[DFPBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait origin:origin] autorelease];
self.adBanner.adUnitID = ADMOB_ID;
self.adBanner.delegate = self;
[self.adBanner setRootViewController:self];
[self.view addSubview:self.adBanner];
GADRequest *request = [GADRequest request];
request.testDevices = #[#"600ecccd6a1c2a4750952facf253ea2f"];
[self.adBanner loadRequest:request];
}
