How to correctly name all those Launch Images for an universal app?

Question

Default.png for iphone, Default4.png for iPhone 4 (or is it Default@2x.png?), and Default-iPad.png. Is that correct?

Answer 1

I adjusted Rob/Lando's answer with the latest iPhone 6 and iPhone 6 Plus resolutions.

• Default.png (iPhone)
• Default@2x.png (iPhone Retina 3.5 inch)
• Default@3x.png (iPhone 6 Plus landscape)
• Default-568h@2x.png (iPhone Retina 4 inch)
• Default-667h@2x.png (iPhone 6 portrait)
• Default-736h@3x.png (iPhone 6 Plus portrait)
• Default-Portrait.png (iPad in portrait orientation)
• Default-Portrait@2x.png (iPad Retina in portrait orientation)
• Default-Portrait@3x.png (iPhone 6 Plus portrait)
• Default-Landscape.png (iPad in landscape orientation)
• Default-Landscape@2x.png (iPad Retina in landscape orientation)
