we have an application built using cocos2d, the first class (scene) called from the app delegate is the levels class which then calls the game class (scene) according to user choice. where should i write my iAd code and how ? any help please.
My suggestion would be to look at AdWhirl, which would make your ads decoupled from the ad network.
More can be found below.

My understanding is that you can not put UIViews directly into CCLayer, or CCScene (i hope those are the names), you will have to shrink your scene in order to put the iAd beside your Cocos2d view.
To implement iAd add the import
#import <iAd/ADBannerView.h>
If you initialize iAd in the AppDelegate, it will displayed everywhere.
This is very easy to achieve.
ADBannerView* iAdView = [[ADBannerView alloc] initWithFrame:CGRectZero];
iAdView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
[[[CCDirector sharedDirector] openGLView] addSubview:iAdView];
For more information, look at apples programming guide http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/iAd_Guide/Introduction/Introduction.html
I recently wrote a post about this issue (integrating iAd in a Cocos2d-x game) in my blog. Take a look and ask me if you have any questions.

Do I need iPhone developer certificate and the app available on the app store in order to implement game center.
Is it easy to implement game center leader boards into your game and if so any tutorials on doing so. I have a score counter already ,but not sure how I would add it into game center.
Any good tutorials on implementing game center into cocos2d and if so may I see a link (yes I have seen some tutorials ,but I want to be recommended a good tutorial).
You need an iPhone developer account to test and implement game center. You don't need to have an app on the App Store you can just test it on an unreleased project. I suggest you read the following tutorial, which explains everything about leaderboards pretty clearly:
Leaderboards Tutorial
Yes - but you would anyway to test on a device. And no, you have a 'sandboxed' version of Game Centre where games not on the app store/ development builds are tested.
Implementing leader-boards difficulty depends on what version of cocos2D you are using. From experience version 1 is a little more challenging then 2. Here is some code on how I have implemented it;
- (void)showLeaderboardForCategory:(NSString *)category
{
// Create leaderboard view w/ default Game Center style
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
// If view controller was successfully created...
if (leaderboardController != nil)
{
// Leaderboard config
leaderboardController.leaderboardDelegate = self; // The leaderboard view controller will send messages to this object
leaderboardController.category = category; // Set category here
leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
// Create an additional UIViewController to attach the GKLeaderboardViewController to
myViewController = [[UIViewController alloc] init];
[[[CCDirector sharedDirector] openGLView] addSubview:myViewController.view];
// Tell UIViewController to present the leaderboard
[myViewController presentModalViewController:leaderboardController animated:YES];
}
}
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)leaderboardController
{
[myViewController dismissModalViewControllerAnimated:YES];
myViewController.view = nil;
[myViewController release];
}
(Credit to the SO post that I originally used though - Leaderboard doesn't add in the screen cocos2d)
The Rod Strougo and Ray Wenderlich book "Learning Cocos2d" (2012) gives some good sample code for implementing game center leaderboards and achievements. Also "Learn cocos2d Game Development with iOS5" by Itterheim and Loew gives good examples too.
I followed the Strougo examples and it worked more-or-less the first time. But something people get stuck on (I did) is how to test. If you don't do it right it will seem like it isn't working when it actually is. It sounds like you haven't gotten started with GC yet so I won't try to explain what to do. Just be aware when the time comes to test that there is a procedure you need to follow that isn't completely obvious.
I have a very simple game using Xcode v4.2.1, Cocos2d v5.0.1. I've tried both compilers in Xcode (LLVM GCC 4.2 and Apple LLVM compiler 3.0. Is there a preference??) On the game screen is a UIKit button that presents the user with a Interface Builder (nib) Settings/Options screen to customize the game a bit. This is all based on what I learned in Ray Wenderlich's tutorial (http://www.raywenderlich.com/4817/how-to-integrate-cocos2d-and-uikit).
After the user makes their changes, they are returned to the game and the changes are in place.
This all works as I want in the simulator, however, when I test the game on an iPad I get the following errors in the debug window:
2012-01-27 18:25:27.305 BonkBonk[1082:707] failed to call context
2012-01-27 18:25:27.310 BonkBonk[1082:707] cocos2d: surface size: 1024x768

OpenGL error 0x0506 in -[EAGLView swapBuffers]
OpenGL error 0x0506 in -[EAGLView swapBuffers]
OpenGL error 0x0506 in -[EAGLView swapBuffers]
The OpeenGl errors continue on indefinitely.
I use the function viewWillAppear to capture the return from the settings/options screen so that I can pass the new settings to the game layer. If I comment out this code the problem goes away, however, I am not able to get the new user settings to the game layer.
Here is the code:
- (void) viewWillAppear:(BOOL)animated
{
[self.navigationController setNavigationBarHidden:YES animated:animated];
//CCScene *scene = [[CCDirector sharedDirector] runningScene];
CCScene *scene = [BonkBonkLayer scene];
id layer = [scene getChildByTag:1];
[layer userSettings];
[super viewWillAppear:animated];
}
The commented out line //CCSene *scene... was another failed attempt at getting the layer object from the scene so that I could call the userSettings method where the game layer then can assimilate it into the game.
OK, so I've found something that alleviates my issue.
If anyone knows anything about this, please let me know. I will continue to use this fix unless I hear a reason from someone more knowledgable than myself (and that's not that difficult).
The solution is found in the comment by "psionic" at the end of the following discussion:
http://www.cocos2d-iphone.org/forum/topic/7068.
Basically, I created a static bool in the EAGLView class (EAGLView.m) that surrounds the call to _resizeFromLayer in the layoutSubViews member function. The call to _resizeFromLayer is only called the first time through, and then never again.
Please read the above discussion and let me know what you like/dislike about this solution, other than the obvious... it's a hack.
A hack,that works. I think.
I had a similar problem. I've integrated cocos2d with UIKit. I added adMob. The problem shows up when user clicks on Ads that presents the google BrowserView. If you dismiss the View using the Done button, the App works fine. However, if user press the Home button when in Browser View, and resume the App, I got the same exception.
OpenGL error 0x0506 in -[EAGLView swapBuffers]
UIKit buttons and the Ads are shown, but it does not render the cocos2d layer.
I got the solution from https://github.com/cocos2d/cocos2d-iphone/pull/198, but I did not change the cocos2d source. Instead, I added a boolean ivar called isAnimating in AppDelegate.m, and expose the property to the Layers.
To solve this, I stop animation on CCDirector before entering google Browser View. and start animation once resume to the App. isAnimating ivar is used to check that start animation is not called twice.
Hope it helps,
I had similar errors in my app when implementing Cocos2D via CCGLView.
The solution that worked for me was to call
[[CCDirector sharedDirector] popScene]
when presenting the Interface Builder Viewcontroller.
I have an application that needs to detect a shaking motion to start/restart its activity. It is already on-Line, but now I want to add the new feature of iAd. I've implemented all the needed methods, but I have a problem: when I enter the Ad and then exit, the device can't catch the shaking motion anymore.
Ideas? Hint.
Thank you.
In the below stackoverflow link:- How to use Shake API in iPhone SDK 3.0?
detailed info is provided. check this.
hope it helps
Solved, actually I get the problem reading diggin into answers linked by Srinivas.
The problem was that when the Ad is end and returns back the control to my UIViewController, this one is no more the First Responder setted on his view. The solution:
- (void)bannerViewActionDidFinish:(ADBannerView *)banner {
[[self view] becomeFirstResponder];
}
Nothing more.
I just finished my concept for an iphone app. I have a main program and in that program I want to start a game.

Cocos2d Game
Is this possible? To use cocos2D in a normal "iphone app"???
Thanks so much!!!
It is definitely possible to mix UIKit with Cocos2d. Usually people accomplish this by putting their UIKit views inside a Cocos2d layer. It sounds like you want to embed the Cocos2d game inside a UIKit view instead. This should be possible, but I am unsure of the specifics involved. Try looking at -(BOOL)attachInView:(UIView *) view in CCDirector.
Note that Cocos2d uses OpenGL and there are possible performance issues when mixing OpenGL and UIKit. Pausing Cocos2d when using the other part of your application will help.
I found a vast array of great tutorials on Cocos2D for iPhone at Ray Wenderlich's site. One tutorial you might especially want to check out is
How to integrate Cocos2D and UIKit
Note: the original "Cocos2D" framework was written in Python and not designed for iOS; here's the actual homepage for the iOS port.
It is possible, but you should know that the main core of your app must be controlled by Cocos2D, that means CCDirector needs to be instantiated in AppDelegate.
Start with:
a). install Cocos2D:
Go to Terminal and write (if you save cocos2D file in desktop, if not use the path where you save it)
cd Desktop/cocos2d-iphone-1.1-beta
sudo ./install-templates.sh
and if you couldn't install try again with
./install-templates.sh -f -u
b). Import cocos2d.h inside AppDelegate
c). Declare CCDirector in applicationDidFinishLaunching method inside
AppDelegate (you should check the code for this in Cocos2D template is pretty straight
forward)
I did this in my applicationDidFinishLaunching method:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[window setUserInteractionEnabled:YES];
[window setMultipleTouchEnabled:YES];
CCDirector *director = [CCDirector sharedDirector];
// Create an EAGLView with a RGB8 color buffer, and a depth buffer of 24-bits
EAGLView *glView = [EAGLView viewWithFrame:[window frame]
pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8
depthFormat:0 // GL_DEPTH_COMPONENT16_OES
];
[glView setMultipleTouchEnabled:YES];
// attach the openglView to the director
[director setOpenGLView:glView];
// Enables High Res mode (Retina Display) on iPhone 4 and maintains low res on all other devices
if( ! [director enableRetinaDisplay:YES] )
CCLOG(#"Retina Display Not supported");
// make the OpenGLView a child of the main window
[window addSubview:glView];
// make main window visible
[window makeKeyAndVisible];
GameScene *gs = [GameScene node];
[[CCDirector sharedDirector] runWithScene:gs];
//General is part of UIKit where I load the tabbar
General *principal;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
principal = [[General alloc] initWithNibName:#"General-iPad" bundle:nil];
} else {
principal = [[General alloc] initWithNibName:#"General" bundle:nil];
}
self.general = principal;
[principal release];
[self showUIViewController:general];
}
To push a scene from tabbar in UIKit
[[CCDirector sharedDirector] pushScene: [CCTransitionMoveInB transitionWithDuration:0.0f scene:[MyScene scene]]];
Next I recommend you to follow Ray Wenderlich's tutorial How to integrate Cocos2D and UIKit and read this post aswell how we can show UIViewController and UIView by using cocos2d? Maybe you should search for some code in the Cocos2D forums too, always help to see that.
EDIT:
1) You can download a easy example from here: UIKit Cocos2D
You could check out this framework too: Kobol2D "is an extended and improved version of the popular Cocos2D for iPhone game engine. Everything you know about Cocos2D can still be applied, and Kobold2D is easier to get started with, more convenient to use, more powerful and flexible than Cocos2D with all the documentation available online and offline. Use Kobold2D to develop iPhone, iPod touch, iPad and Mac OS X games for both Apple App Stores. And it has some examples using UIKIT and Cocos2D".
You can certainly create a game with your requirements in Cocos2D. You might want to ask some follow-up questions over at the Cocos2D forums and read through their documentation.
You can probably do this easily......
You have to only make the (UIView *) view in CCDirector.
after attaching the view.....
Yes.It is very easy and handy to implement Cocos2D with normal Iphone FrameWork.Refer Ray Wenderlich UIKit and Cocos2D Integration Tutorial here.It will helpful to you.
Yes! Is very possible, only install the Cocos2d and his templates.
Inclusive, I used Cocos2d to create simple apps with a lot of effects :)

How can i use picker view in iphone application using cocos2d ?
Is it possible to use pickerview in iphone application using cocos2d ? If possible then can i do that in my application.Where i can get this information.If not then what are the other solution for doing this in pickerview.
I haven't looked into cocos2d at all, but I assume that if you still have access to the UIKit fameworks within your app you should be able to create an instance of UIPickerView.
However, I'm not sure you'll be able to used it the way you're intending without some subclassing or writing your own. The picker view is intended to be used by the user to pick an item from a selection, not to be automatically spun by the app...
Yes you can use UIKit controls in Cocos2DIPhone.
You just need to attach them directly to the application window.
There are examples in the docs and on the cocos2d message board. Riq is excellent with questions/feedback on the message board there as well.
I have used the UIImagePicker controller in my application using the steps below:
// 1 - instantiate your picker (in my case UIImagePicker):
pickerController = [[UIImagePickerController alloc] init];
pickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
pickerController.delegate = self;
// 2 - add the picker view as a subview of the actual scene
[[Director sharedDirector] openGLView] addSubview:pickerController.view];
It worked for me but the transition is not animated.
