Disable iPad Retina in Cocos2d v 3

In Cocos2d 2.0, I used below code to disable retina for iPad.

     if(!IS_IPAD)   //In AppController.m
     {
        [director_ enableRetinaDisplay:YES];
     }

Now AppDelegate not has these calls. How to disable retina for iPad only ?

You might want to explore this. I do the same because i want to run all devices from a single set of textures ... and my textures are very 'potent' on all devices, looks fine.

this setup creates a ScreenViewPort that is constant size on all devices , 568x384. All my 'full background' textures are at 1136x768 pixels, able to display all devices. This simplifies layout drastically, but there is a small price to pay. World(0,0) is not ScreenViewPort(0,0). For example, when running on a 4in iPhone (568x320), ScreenViewPort bottom-left is at 0,32 , on an iPad it is at 28,0 ...

Our mileage may vary with new display sizes for iPhone 6, i'll cross that river when i get myself some devices and can ascertain the 'workability' of this.

in AppDelegate :

NSString *kCCFileUtilsSuffixDefault = @"default";
NSString *kCCFileUtilsSuffixiPad = @"ipad";
NSString *kCCFileUtilsSuffixiPadHD = @"ipadhd";  
NSString *kCCFileUtilsSuffixiPhone = @"iphone";
NSString *kCCFileUtilsSuffixiPhoneHD = @"iphonehd";
NSString *kCCFileUtilsSuffixiPhone5 = @"iphone5";
NSString *kCCFileUtilsSuffixiPhone5HD = @"iphone5hd";
//NSString *kCCFileUtilsSuffixMac = @"mac";
//NSString *kCCFileUtilsSuffixMacHD = @"machd";

NSDictionary *dic = [CCFileUtils sharedFileUtils].suffixesDict;
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixDefault];
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixiPhone];
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixiPad];
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixiPadHD];
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixiPhoneHD];
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixiPhone5];
[dic setValue:@"-hd" forKey:kCCFileUtilsSuffixiPhone5HD];

[self setupCocos2dWithOptions:@{
        // Show the FPS and draw call label.
        CCSetupShowDebugStats : @(YES),

        // More examples of options you might want to fiddle with:
        // (See CCAppDelegate.h for more information)
        // Use a 16 bit color buffer:
        // CCSetupPixelFormat: kEAGLColorFormatRGB565,

        // Use a simplified coordinate system that is shared across devices.
        CCSetupScreenMode : CCScreenModeFixed,

        // Run in landscape mode.
        CCSetupScreenOrientation : CCScreenOrientationLandscape,

        // Run at a reduced framerate.
        CCSetupAnimationInterval : @(1.0 / 30.0),

        // Run the fixed timestep extra fast.
        CCSetupFixedUpdateInterval : @(1.0 / 60.0),

        // Make iPad's act like they run at a 2x content scale. (iPad retina 4x)
       //       CCSetupTabletScale2X: @(YES),
}];

[CCTexture PVRImagesHavePremultipliedAlpha:YES];

and in CCFileUtils , a minor mod :) 

-(CGFloat) contentScaleForKey:(NSString*)k inDictionary:(NSDictionary *)dictionary{
    // XXX XXX Super Slow
    // ylb fix for single set of textures
    return 2.0f;
    // ylb fix : super fast now :)
}
