Advertisements not removed after IAP unless app is restarted? - iphone

Question

In my app, there is code that, if a button is pressed the user can upgrade the app and remove the advertisements, it calls the MKStoreKit and once the user purchases the upgrade, the adverts do remain in the app UNTIL the app is restarted.
I want to fix this, so the advertisements are removed immediately, but how would I go about doing this?
Here is some of the code;
-(IBAction)removeAds:(id)sender
{
if (![MKStoreManager isFeaturePurchased:#"com.davidsapps.puzzler.removeads"]) { //
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Upgrade App" message:#"To upgrade and remove all advertisements from this app Please click OK to purchase the upgrade!" delegate:self cancelButtonTitle:#"No Thanks" otherButtonTitles:#"Yes Please",nil];
[alert show];
[alert release];
}
}
The alert it links to;
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:#- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:#"com.idevver.mybatterypal.upgrade"];
}
}
}
Using MKStoreKit
Is there anything I can do to make it remove the advertisements without the user having to restart the app?
Thanks,
Chris
EDIT - the advertisements are Admob Mediation, using this code in the ViewDidLoad
- (void)viewDidLoad {
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
bannerView_.adUnitID = MY_BANNER_UNIT_ID;
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGFloat screenHeight = screenRect.size.height;
CGFloat screenXPos = (screenWidth /2);
CGFloat screenYPos = screenHeight - 90;
[bannerView_ setCenter:CGPointMake(screenXPos, screenYPos)];
bannerView_.rootViewController = self;
bannerView_.adUnitID = MY_BANNER_UNIT_ID;
bannerView_.rootViewController = self;
[self.view addSubview:bannerView_];
This is the code that actually calls the advertisement banner, it is in an if/else statement later in the viewDidLoad
if (![MKStoreManager isFeaturePurchased:#"com.davidsapps.puzzler.removeads"]) { //
[bannerView_ loadRequest:[GADRequest request]];
}
So I guess somehow when the feature is purchased, I need to add to the MKStoreManager.m file something to say dismiss the bannerView_ code above?
Would that work?

When the purchase completes, it is up to you to remove the ads. Do something similar to this.
[bannerView removeFromSuperview];
All you have to do is hide the ads when the purchase completes.
