Why my whole image is not displayed while running app in iphone (Retina 4 inch)

Question

I set background of view as below:

self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:
@"backgr.png"]];

It is working fine when i run it in iphone 4(Retina 3.5-inch). But when i run it in iphone 5(Retina 4-inch) image didn't set or displayed correctly.Image looks like 4 times zoom in/ blows up.

EDIT:

 I have two different images for iphone 4(640x960) and 5(640x1136).

 What is the problem here? Is it scaling problem or another problem?
 Please guide me on this.

the resolution for both the displays are different so you need to put condition and accordingly set the new image with higher resolution for iPhone 5 (4 inch retina) display.

and that condition you can put like

if ((int)[[UIScreen mainScreen] bounds].size.height == 568)
{
    // This is iPhone 5 screen
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"backgr_iPhone5.png"]];
} else {
    // This is iPhone 4 screen
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"backgr.png"]];
}

Here is something that can be handy :

#define IS_PHONEPOD5() ([UIScreen mainScreen].bounds.size.height == 568.0f && 
[UIScreen mainScreen].scale == 2.f &&
 UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

and

- (void)viewDidLoad
{
    [super viewDidLoad];

        if(IS_PHONEPOD5())
        {
                self.imageView.image = [UIImage imageNamed:@"image-568h@2x"];
        }
        else
        {
                self.imageView.image = [UIImage imageNamed:@"image"];
        }
}

You need to use two different image for iPhone 4 and iPhone 5.Because both device have different resolution. You need to check like this.

if ([UIScreen mainScreen].bounds.size.height == 568)
    {
        // ------- iPhone 5
    }
    else
    {
        // ---------- iPhone 4
    }
