Force ADBannerView to rotate (Not "orientation" but actual transform)

Question

this is NOT a how do I force orientation of my app question as it might look like.

My problem is probably very simple, but it is hard to describe it so here goes.

I am trying to implement iAd to my iphone game. This is not a problem, it was a 10 minute fix, just follow tutorials on the web. However, my game was programmed by a contractor since I can't program very well and he made the game translated to landscape orientation instead of oriented to landscape. This has leads to some problems for me when trying to rotate the ads correctly.

Bottom line is that CGRect which is what iAd uses does simply not have the transform function so no matter what I do the ads are standing on their side. This is quite natural since the app doesn't know that the game is meant to be played in landscape.

After a full day of research it seems that I need to put my iAd CGRect in a different view and rotate that view using the CGAffineTransformMakeRotation. My really big problem is that I am not good enough at Objective-C to actually do that.

So can you help me how I should be able to apply transform to my ad?

Code below compiles and shows the ad but standing on its side (when holding the game in landscape)

//iAD starts
// lower right:-136, 295, 320, 32    lower left:-136, 135, 320, 32   upper right:136, 295, 320, 32
// *Controller becomes a UIViewController
UIViewController *controller = [[UIViewController alloc] init];
controller.view.frame = CGRectMake(100, 100, 320, 32);
//controller.view.transform = CGAffineTransformMakeRotation(M_PI / 2.0); // turn 180 degrees
NSLog(@"*controller");  


    //adView becomes a CGRectZero called adView
adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
//adView.frame = CGRectOffset(adView.frame, 0, 0);
adView.requiredContentSizeIdentifiers = [NSSet setWithObjects:ADBannerContentSizeIdentifierLandscape,ADBannerContentSizeIdentifierPortrait,nil];
adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
[self.view addSubview:adView];


adView.delegate=self;

//self.bannerIsVisible=NO;

// iAD ends

This should rotate as you are asking. This code has worked for me in my iAd apps: Directly from Apple Source Code

.h

#import <UIKit/UIKit.h>
#import <iAd/iAd.h>

@interface TextViewController : UIViewController <ADBannerViewDelegate>
{
    UIView *contentView;
    ADBannerView *banner;
}

@property(nonatomic, retain) IBOutlet UIView *contentView;
@property(nonatomic, retain) IBOutlet ADBannerView *banner;

@end

.m

#import ".h"

@interface TextViewController()

// Layout the Ad Banner and Content View to match the current orientation.
// The ADBannerView always animates its changes, so generally you should
// pass YES for animated, but it makes sense to pass NO in certain circumstances
// such as inside of -viewDidLoad.
-(void)layoutForCurrentOrientation:(BOOL)animated;

// A simple method that creates an ADBannerView
// Useful if you need to create the banner view in code
// such as when designing a universal binary for iPad
-(void)createADBannerView;

@end

@implementation TextViewController

@synthesize contentView, banner;

-(void)viewDidLoad{
    [super viewDidLoad];
    // If the banner wasn't included in the nib, create one.
    if(banner == nil)
    {
        [self createADBannerView];
    }
    [self layoutForCurrentOrientation:NO];
}

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [self layoutForCurrentOrientation:NO];
}

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
    return YES;
}

-(void)willAnimateRotationToInterfaceOrientation:  (UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
    [self layoutForCurrentOrientation:YES];
}

-(void)createADBannerView{
    // --- WARNING ---
    // If you are planning on creating banner views at runtime in order to support iOS targets that don't support the iAd framework

If the game is rotated, why don't you stop the rotation of the game?

Answer 3

I managed to do what I wanted by using a different ad SDK (mobfox) the rotation I wanted to do looks like this:

// MOBFOX Starts
// create the banner view just outside of the visible area
MobFoxBannerView *bannerView = [[MobFoxBannerView alloc] initWithFrame:
                                CGRectMake(-800, self.view.bounds.size.height - 240, 320, 50)];
bannerView.delegate = self;  // triggers ad loading
//bannerView.backgroundColor = [UIColor darkGrayColor]; // fill horizontally
bannerView.transform = CGAffineTransformMakeRotation(M_PI / 2.0); 
//bannerView.refreshAnimation = UIViewAnimationTransitionCurlDown;
[self.view addSubview:bannerView];

NSLog(@"MobFox: Ad initated and placed offscreen");

//

The transform = CGAffineTransformMakeRotation was not accepted by the iAd stuff and since I am too weak on objective-c to force it to my will. This is what I did.

Thanks for offering to help!
