You don’t have to have each image in all scales if it won’t be used. Make only the sizes you need and name them according to their width. For portrait full-device-width images, you need 320px wide at 1x and 2x, 375px wide at 2x and 414px wide at 3x. 4″ devices used “-568h” suffix for … Read more
It seems to me that a lot of these answers want to address how to constrain the imageView, where I think you are concerned with loading the correct media file? I would come up with my own future extensible solution, something like this: “UIImage+DeviceSpecificMedia.h” – (a category on UIImage) Interface: #import <UIKit/UIKit.h> typedef NS_ENUM(NSInteger, thisDeviceClass) … Read more
As stated by rmaddy in the comments, if you are supporting iOS < 8, you still need to do this: General / App Icons and Launch Images Launch Image Source – select LaunchImage for asset catalog. Add a 640×1136 image for the “Retina 4” option. So I guess the LaunchScreen.xib is useless if you target … Read more
I found a workaround that makes landscape only launch images work on iOS 8 GM. I ended up using the UILaunchImages array in Info.plist. The trick is to get image to show up that doesn’t explicitly support landscape (iPhone 4/4S, iPhone 5/5S/5C, iPhone 6) you need to specify duplicate entries. See my example below. This … Read more

The iPhone 6+ renders internally using @3x assets at a virtual resolution of 2208×1242 (with 736×414 points), then samples that down for display. The same as using a scaled resolution on a Retina MacBook — it lets them hit an integral multiple for pixel assets while still having e.g. 12 pt text look the same size … Read more
You can add a launch screen file that appears to work for multiple screen sizes. I just added the MainStoryboard as a launch screen file and that stopped the app from scaling. I think I will need to add a permanent launch screen later, but that got the native resolution up and working quickly. In … Read more
