iAd in UITableViewController

Question

I have a UITableViewController that I want to add iAds to. I want the ad to display at the bottom of the screen at all times. I have followed the answer here: https://stackoverflow.com/a/9857798/2584268 and have achieved this behavior. However, the ad is hidden in the beginning and only appears when the user scrolls the table. How can I get the ad to appear at the bottom of the screen when the view loads, not just when the user scrolls?

Answer 1

To show the ad when the view appears, I add the banner view on viewDidAppear.

- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];

_myIAD = [[self appdelegate] myIAD];

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
    //iPhone code
    if ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)
    {
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 50, 320, 50);
        }
        else
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 114, 320, 50);
        }
    }
    else if ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeRight)
    {
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 32, 480, 32);
        }
        else
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 84, 480, 32);
        }
    }
}
else
{
    //iPad code
    if ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)
    {
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 66, 768, 66);
        }
        else
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 130, 768, 66);
        }
    }
    else if ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeRight)
    {
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 66, 1024, 66);
        }
        else
        {
            _myIAD.frame = CGRectMake(0, _myTableView.frame.size.height - 130, 1024, 66);
        }
    }
}

[self.view addSubview:_myIAD];
}

There is a ton of code in there to deal with iOS6.1 and iPads and iPhones, but it works real well. I always like to use the statusBarOrientation to find the orientation, it works better.

As you can see there is a line

_myIAD = [[self appdelegate] myIAD];

I actually make the banner in the app delegate and use it in all the view controllers. To handle rotation, I register for a notification in viewDidLoad.

- (void)viewDidLoad
{
[super viewDidLoad];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateUI:) name:UIDeviceOrientationDidChangeNotification object:nil];
}

And basically use the same code in the viewDidAppear in the method updateUI:

The only other thing I did was to put in this code to keep the iAd at the bottom.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGRect frame = _myIAD.frame;
frame.origin.y = _myTableView.contentOffset.y + _myTableView.frame.size.height-_myIAD.frame.size.height; // Move view to the bottom on scroll
_myIAD.frame = frame;
[_myTableView bringSubviewToFront:_myIAD];
}
