iAd For Complete Noobs

Sub these three files in for your current, to get iAd on iPhone on Xcode. I’m not sure it works on iPad. So if you’re planning for a universal application then this is not the tutorial you’re gonna want. (Also before you can run this you need to add the iAd.framework to your frameworks.) Also thanks to reefwing for most of this code.
CodeaViewController.h:

//  CodeaViewController.h

#import <UIKit/UIKit.h>

@protocol CodeaAddon;

typedef enum CodeaViewMode
{
    CodeaViewModeStandard,
    CodeaViewModeFullscreen,
    CodeaViewModeFullscreenNoButtons,
} CodeaViewMode;

@interface CodeaViewController : UIViewController

@property (nonatomic, assign) CodeaViewMode viewMode;
@property (nonatomic, assign) BOOL paused;

- (void) setViewMode:(CodeaViewMode)viewMode animated:(BOOL)animated;

- (void) loadProjectAtPath:(NSString*)path;

- (void) registerAddon:(id<CodeaAddon>)addon;

@end

AppDelegate.h:

//  AppDelegate.h

#import <UIKit/UIKit.h>
#import "IAdsAddOn.h"

@class CodeaViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) CodeaViewController *viewController;

@property (strong, nonatomic) IAdsAddOn *iAdsAddOn;;

@end

-Note: you’ll need to paste your project name where it says PROJECTNAME
AppDelegate.mm:

//  AppDelegate.mm

#import "AppDelegate.h"
#import "CodeaViewController.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.viewController = [[CodeaViewController alloc] init];
    
    //  Create and add our iAdsAddOn to Codea
    
    self.iAdsAddOn = [[IAdsAddOn alloc] init];
    [self.viewController registerAddon: self.iAdsAddOn];
    
    NSString* projectPath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"PROJECTNAME.codea"];
    
    [self.viewController loadProjectAtPath:projectPath];
    
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    
    return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application
{
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
}

- (void)applicationWillTerminate:(UIApplication *)application
{
}

@end

Don’t worry when you encounter errors it’s because you need to also add these (last) two files to your addons folder. Make sure these files are in Xcode and not just in your project folder.
IAdsAddOn.h:

//  IAdsAddOn.h

#import "CodeaAddon.h"
#import <iAd/iAd.h>
#import <Foundation/Foundation.h>

//#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
//#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
//#define IS_IPHONE_5 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0f)
//#define IS_IPHONE_4 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 480.0f)

I hope this helps you!
if this doesn’t make sense then try this website:

What about making it for @Zoyt’s Obj-C addon? Last I heard, Reefwing’s is a bit outdated and has errors, and Zoyt’s has some extra functions.

I’m not sure I haven’t tried it yet. @SkyTheCoder It’s interesting how man important discussions go unnoticed by everyone. About a month ago I was looking for a fullscreen iAd tutorial and couldn’t find one, but it’s been right in front of me this whole time.
