ios - xcode when i run program on iphone 5 screen looks iphone 4

Question

I'm using Xcode 6 and use objective-c when i test program on iOS 8 (iPhone 5) program run without error but when i try to test program on iOS 7 (iPhone 5) screen look like iPhone 4 screen. I can detect phone like this;

#define iPhone6Plus ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 736)
#define iPhone6 ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 667)
#define IS_IPHONE_5 ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 568)
#define IS_IPAD UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad

and also i can detect operating system like this;

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_0)
{
    #define IS_IPHONE_5 ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 568)
}

When i do this screen not scale on phone because when i run on iOS 7 phone screen run like iPhone 4 check image for more description.

Set an iPhone 5 launch screen. It will be fixed.

iPhone 5 launch screen spec: 640x1136

For the time being create a blank screen on photoshop or preview. You can replace it later.
