I have a iPad app with 2 view controllers; 1st one is for the UI, the 2nd for a view which displays help from a UIWebView. When I go back and forth 10 times between view controllers, I get the message in the title above on exactly the 10th time returning to the first VC.
This is my code in VC #1:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
adView = [[ADBannerView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 50, 320, 50)];
_adBanner = [[ADBannerView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height, 320, 50)];
_adBanner.delegate = self;
[self.view addSubview:adView];
}
- (void) viewWillDisappear:(BOOL)animated {
[_adBanner removeFromSuperview];
_adBanner.delegate = nil;
_adBanner = nil;
}
- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
if (!_bannerIsVisible) {
// If banner isn't part of view hierarchy, add it
if (_adBanner.superview == nil)
[self.view addSubview:_adBanner];
// }
[UIView beginAnimations:@"animateAdBannerOn" context:NULL];
// Assumes the banner view is just off the bottom of the screen.
banner.frame = CGRectOffset(banner.frame, 0, -banner.frame.size.height);
[UIView commitAnimations];
_bannerIsVisible = YES;
}
}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
NSLog(@"Failed to retrieve ad");
if (_bannerIsVisible) {
[UIView beginAnimations:@"animateAdBannerOff" context:NULL];
// Assumes the banner view is placed at the bottom of the screen.
banner.frame = CGRectOffset(banner.frame, 0, banner.frame.size.height);
[UIView commitAnimations];
_bannerIsVisible = NO;
}
}
I know why, just don't know how to fix it. Can someone please help me with this?
