You need to create design for iPhone 4 and iPhone 5.

Create a class which make decision which iPhone is connected and make function on it which accept CGRect and return required size of CGRect

you can get device size by

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
    {
        CGSize result = [[UIScreen mainScreen] bounds].size;
        if (result.height < 500)
        {
            currentDeviceHeight=460;
            //You can use use iPhone 4 image

        }
        else
        {
            currentDeviceHeight=548;
            // here you can use iPhone 5 image
        }
    }
    else
    {
         // iPad
    }

Iphone 5 size is 568 and Iphone 4 size is 480.

scrollView=[[UIScrollView alloc]init];

if ([[UIScreen mainScreen] bounds].size.height == 568) 
{  

    // For Iphone5
scrollView.frame = CGRectMake(0, 0, 320, 568)
}
else if ([[UIScreen mainScreen] bounds].size.height == 480) 
{
   //For Iphone 4 or others
scrollView.frame = CGCGRectMake(0, 0, 320, 480)
}

this will really helpful to you.

Use macro to check whether it is iPhone 5 or not.

#define IS_IPHONE ( [[[UIDevice currentDevice] model] isEqualToString:@"iPhone"] | [[[UIDevice currentDevice] model] isEqualToString:@"iPhone Simulator"])
#define IS_HEIGHT_GTE_568 [[UIScreen mainScreen ] bounds].size.height >= 568.0f
#define IS_IPHONE_5 ( IS_IPHONE && IS_HEIGHT_GTE_568 )

scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, IS_IPHONE_5?568:480)];

Iphone 5 screen size is 568 and you have had codded height to 480. So it is not working for iphone5. DO following 

scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, [[UIScreen mainScreen] bounds].size.height)];

Depending on devise scroll view height will change.

Try This

scrollView=[[UIScrollView alloc]init];

if ([[UIScreen mainScreen] bounds].size.height == 568) scrollView.frame = CGRectMake(0, 0, 320, 568)
else if ([[UIScreen mainScreen] bounds].size.height == 480) scrollView.frame = CGRectMake(0, 0, 320, 480)

So, it will help you to fill scrollview in iPhone-5 screen too.

Hopefully, it'll work for you.

Thanks.
