Xcode 6 how to set separate @2x images for iPhone 5 and 6 devices?

Question

I want to specify different background images for iPhone each device. Like this

iPhone 6 Plus   1242x2208 pixels    [email protected]
iPhone 6        750x1334  pixels    [email protected]
iPhone 5        640x1136  pixels    [email protected]
iPhone 4        640x960   pixels    [email protected]
iPhone 3GS      320x480   pixels    bg.png

In LaunchImage there is option available to specify images for Retina HD 4.7 device. So no problem for Launch Images.

In .xcassets file, I have option for 1x, 2x, Retina 4 2x and 3x. But there is no option for iPhone 6 (1334x750) device.

So how to provide 1334x750 px image for iPhone 6 device? Looking for some solution using .xcassets file, not by programmatically loading images for each device.

I have already visited the related SO's questions, but none of them answers specifically for iPhone 6 device images.

Answer 1

set your image name like this;

image-320@2x//iPhone 5

image-375@2x//iPhone 6

NSNumber *screenWidth = @([UIScreen mainScreen].bounds.size.width);
NSString *imageName = [NSString stringWithFormat:@"image-%@", screenWidth];
UIImage *image = [UIImage imageNamed:imageName];

Answer 2

Images.xcassets has option to provide separate image for iPhone 5(Retina 4 @2x), iPhone 6(@2x) and iPhone 6 plus(3x).

There is no option for iPhone 4 asset(probably apple is stopping iPhone 4 support) rather it takes @2x images (scale mode) for iPhone 4 also but you can do something like This post for iPhone 4

Update Xcode 7

There is no option for separate image with Images.xcassets now in Xcode 7, We have to use same 2x images for all Retina devices and 3x for Retina HD device
