I just worked with two screen sizes, but now that the new iPhone 6/6 + is being announced , I need to deal with four screen sizes. So how can I specify initial images for these new devices
Thanks in advance
Update

In the .xcassests file , I found new settings added to Xcode 6 GM , which ( Retina HD 5.5 ) and ( Retina HD 4.7 ), I think it’s easy to find which one is for iPhone 6, and for iPhone 6+, but which name for these boot images by default.
because I usually do not work with the .xcassests file
3.5 inches = Default.png
(320px x 480px)
3.5 inches (with retina) = Default@2x.png
(640px x 960px)
4.0 = Default-568h@2x.png
(640px x 1136px)
4.7 = ??
(750px x 1334px)
5.5 = ??
(1242px x 2208px)
Answer:
:
3.5 inch screen: LaunchImage-700@2x.png
4.0 inch screen: LaunchImage-700-568h@2x.png
4.7 inch screen: LaunchImage-800-667h@2x.png
5.5 inch screen: LaunchImage-800-Portrait-736h@3x.png
