Want a nice, easy to read and implement description of blend modes in Cocos2D? Well you won’t get it here on Tokeru, but you will on Nial Giacomelli’s site. Check it out.

Orientation always in Portrait iOS6

Posted in code on October 1st, 2012 by admin – Be the first to comment

Right had to do a bit of research for this one, here is the fix I found that works from Natalie London


NSString *reqSysVer = @"6.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];

if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending){
    [window setRootViewController:viewController]; // This is for IOS6.....
    [window addSubview: viewController.view]; //This is for < IOS6....... (the old way)

In your ROOTVIEWCONTROLLER.m //will only be compiled for IOS6


- (NSUInteger) supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationLandscapeRight;

- (BOOL) shouldAutorotate {
    return YES;


- (NSUInteger) supportedInterfaceOrientations {
    return¬† UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationPortrait;

- (BOOL) shouldAutorotate {
    return YES;

Project Code for Universal App Creation

Posted in code on March 29th, 2012 by admin – Be the first to comment

Step 1

In your Target Info set the Targeted Device Family to “iPhone/iPad”

Step 2

In your appDelegate.m put this bit of code

 - (BOOL) isIpad {
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        return YES;
    } else {
        return NO;
    return NO;

To reference it in your other classes do this

in class.h

@interface YourLayerClass : CCLayer {
    YourAppDelegate *theDelegate;
    Boolean *isIpad;

in class.m in your init method

-(id) init
    if( (self=[super init] )) {

                //DEFINE iPad or iPhone
        theDelegate = (YourAppDelegate*)[[UIApplication sharedApplication] delegate];
        isIpad = [theDelegate isIpad];


And you can use it in your class thusly

    if(isIpad == NO){
    bg = [CCSprite spriteWithFile:@"xx_iphone.png"];
    }else {
    bg = [CCSprite spriteWithFile:@"xx_ipad.png"];

simple cocos2d animation using .png sequence

Posted in code on March 6th, 2012 by admin – Be the first to comment

Right, so I do a lot of animation in my apps, so here is the most simple creation of it


@private CCSprite *youranimref;
@private CCAnimation *animation;


-(id) init
    if( (self=[super init] )) {
        self.isTouchEnabled = YES;
        size = [[CCDirector sharedDirector] winSize];
        animation = [[CCAnimation alloc] initWithName:@"youranimref" delay:1/24.0];
        youranimref = [CCSprite spriteWithFile:@"yourFirstAnimGrfx.png"];
        [animation addFrameWithFilename: @"yourSecondAnimGrfx.png"];
        [animation addFrameWithFilename: @"yourThirdAnimGrfx.png"];
        [animation addFrameWithFilename: @"yourFourthAnimGrfx.png"];

        // ADD ANIMATION
        youranimref.position = ccp( 512, 435 );
        [self addChild:youranimref z:5];

    return self;

- (void) dealloc


    [[CCTextureCache sharedTextureCache] removeUnusedTextures];
    [[CCSpriteFrameCache sharedSpriteFrameCache] removeUnusedSpriteFrames];

    [animation release];
    [super dealloc];

- (void) runAnimation
    CCAnimate* action = [CCAnimate actionWithAnimation:animation];
    [youranimref runAction:action];


Code for multitouch

Posted in code on June 30th, 2011 by admin – Be the first to comment

In my latest app Loopy Tunes, I needed to add multitouch functionality to a keyboard. I use Cocos2D, so if you’re like me, then just do the following.

In your delegate.m class, add this line

[glView setMultipleTouchEnabled:YES];

right after this one.

[director setOpenGLView:glView];

Then in your class.m where you are testing for multitouch, up in your init method, add the following line

self.isTouchEnabled = YES;

And then add your touch method somewhere down under the init method, just update the values of the areaToCheck

- (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
    NSSet *allTouches = [event allTouches];
    for (UITouch* touch in allTouches) {
        CGPoint location = [touch locationInView:[touch view]];
        location = [[CCDirector sharedDirector] convertToGL:location];
        CGRect areaToCheck = CGRectMake(100,100,100,100);
        if(CGRectContainsPoint(areaToCheck, location)) {
            // whatever you want to happen here

Icons required for a universal app

Posted in code on June 30th, 2011 by admin – Be the first to comment

When preparing my universal app for iTunes I was having trouble with getting the icon.png file the right size. When I saved a 57×57 pixel icon iTunes complained about needing a 72×72 pixel icon for the iPad an vice versa for the iPhone. So I googled and found there are a couple of things you need to do.


Create all the icons listed in here under Table 3: Universal apps icon requirements. Then add them to your project in xcode. (you know, drag em into your resources folder)


On that same page down the bottom are the instructions for how to enter these to your info.plist. Follow them, or just add this to your info.plist if it isn’t in there already.¬† (I prefer to edit the info.plist myself in textEdit) If you are using a cocos project, especially 0.99.5 or newer, it should already be in there.

If you have the following in your info.plist,


replace it with


Code – link from your app to the app store

Posted in code on January 20th, 2011 by lucy – Be the first to comment

A good way to get people to review your app easily is to put a link to the review page in your app. Easy to do, just add this

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@""]];

and replace “a-fine-musician” with your app name, and “406573790” with your app id.
