Background color during a flip horizontal animation

I've been looking for a way to change the black background color during a flip horizontal animation, but so far, nothing did the trick for me.

This is what it looks like right now

I'd really appreciate it if anyone could help me! Here is the code that I've been using for the animation:

ViewController.h:

-(IBAction)howitworksbutton:(id)sender;

ViewController.m:

-(IBAction)howitworksbutton:(id)sender 
{
      howitworks *secondview = [[howitworks alloc] initWithNibName:nil bundle:nil];
      secondview.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
      [self presentModalViewController:secondview animated:YES];
}

I also created a new UIViewController subclass called 'howitworks'.

Regards, Ivar

Swift 3:

open fileAppDelegate.swift

inside function didFinishLaunchingWithOptions

add window?.backgroundColor = hexStringToUIColor("#EEEEEE")

something more:

hexStringToUIColor is a helper method, you can use your way to create UIColor

func hexStringToUIColor (_ hex:String) -> UIColor {
    var cString:String = hex.trimmingCharacters(in: .whitespacesAndNewlines).uppercased()

    if (cString.hasPrefix("#")) {
        cString.remove(at: cString.startIndex)
    }

    if ((cString.characters.count) != 6) {
        return UIColor.gray
    }

    var rgbValue:UInt32 = 0
    Scanner(string: cString).scanHexInt32(&rgbValue)

    return UIColor(
        red: CGFloat((rgbValue & 0xFF0000) >> 16) / 255.0,
        green: CGFloat((rgbValue & 0x00FF00) >> 8) / 255.0,
        blue: CGFloat(rgbValue & 0x0000FF) / 255.0,
        alpha: CGFloat(1.0)
    )
}

Try and set the background color of the window object of your app delegate:

YourAppDelegate   *delegate =[[UIApplication sharedApplication] delegate];
[[delegate window] setBackgroundColor:[UIColor redColor]];

I believe this is the main background color that sits behind all of your application views.
