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. http://nial.me/2012/06/porting-photoshop-blendmodes-to-cocos2d/

Archiving

Real quick one, if you are trying to submit your app to iTunes through xcode and you find that the menu item Product->Build For->Build For Archiving is greyed out, then check your build target. It has to be IOS device, not one of the simulators.

Checking IOS version

Posted in code on January 29th, 2013 by lucy – Be the first to comment

Easy as, here it is for 6. You can change to 5’s if that’s what you need.

-(BOOL) isIOS6 {
    if([[[UIDevice currentDevice] systemVersion] floatValue] >= 6.0){
        return YES;
    }else{
        return NO;
    }
}

Xcode – Could not launch app – No such file or directory Error.

Posted in code on November 20th, 2012 by lucy – 2 Comments

I’ve been expanding the amount of devices I have and returning to old code to try and sort out and update code that doesn’t run on newer IOS’s. While trying to compile Loopy Tunes, I came across the error  from Xcode, “could  not launch app, no such file or directory exists..” So here I found the solution due to one helpful blogger,

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

In your APP DELEGATE.m

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

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

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

FOR LANDSCAPE USE THIS

- (NSUInteger) supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationLandscapeRight;
}

- (BOOL) shouldAutorotate {
    return YES;
}

FOR PORTRAIT USE THIS

- (NSUInteger) supportedInterfaceOrientations {
    return  UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationPortrait;
}

- (BOOL) shouldAutorotate {
    return YES;
}

Creating an Ad Hoc version of your app

Posted in code on July 25th, 2012 by admin – Be the first to comment

I could write out how to do this, but I couldn’t do better than this post here.

And in case you need to know how to create your Ad Hoc Distribution Provisioning Profile, look at the Apple notes here

http://developer.apple.com/library/ios/#documentation/ToolsLanguages/Conceptual/DevPortalGuide/CreatingandDownloadingaDistributionProvisioningProfile/CreatingandDownloadingaDistributionProvisioningProfile.html

And if you want to know how to add devices for testing. Get the UDID from the iphone or ipad, and in the the IOS Provisioning Portal go to “devices”. Select “add devices” in the top right corner. Enter the device name and device ID and hit “submit”.

EXC_BAD_ACCESS

Posted in code on May 11th, 2012 by admin – Be the first to comment

Right so I get this one a lot, especially when I’m coding late at night and tired…which is most of the time. So, my main culprits are objects that I haven’t released in my dealloc method.

Especially look for anything that you created with ALLOC INIT, for example an array

[[NSMutableArray alloc] init]

You must, must, must release it.

Second most common is not removing the class from observing a Notification. So if you have something like

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(classMethod:) name:@"notificationName" object:nil];

Then again in your dealloc method, you must put this

[[NSNotificationCenter defaultCenter] removeObserver:self];

I’m sure there are more things, and I’ll add notes as I discover them.
