Answer 1

Can't you just use the @2x suffix?

Eg, you have image fancyBackground.png for regular ipad, and [email protected] for retina display?

When you do this, it will automatically use the correct image for the type of display that the device has (retina devices will use @2x-suffixed image files if they exist).

You can detect if a device is iPad by using:

UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad

You can detect if a device is retina by using:

[[UIScreen mainScreen] respondsToSelector:@selector(scale)] && [[UIScreen mainScreen] scale] >= 2.0

Answer 2

• (NSString *)deviceVersion

{

size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *answer = (char*)malloc(size);
sysctlbyname("hw.machine", answer, &size, NULL, 0);
NSString *platform = [NSString stringWithCString:answer encoding: NSUTF8StringEncoding];
free(answer);
NSLog(@"Platform: %@", platform);

return platform;

}

Here is the method through you can detect weather device is ipad2,ipad3,ipod.. u can return a value and check against a value whatever it is.
