Image Assets catalog doesnt recognise retina 4 pho

Question

For start what I am trying to do i am not even sure that is possible(looks that is) In the feature of image assets in Xcode you can select for an imageSet to be either Universal or Device Specific. When I am doing it Device Specific and select both iphone and Retina 4 and assign pics to all , it is always selected the iphone retina image and never the Retina 4 when I am using an iphone 5(device or simulator)

Have searched docs but couldnt find something. Thanks

Answer 1

The "R4" image will only work on 4-inch iPhone running iOS 7 or later. On older version of iOS it will use 2x image.

Example. If you use images like this:

you will see:

• iPhone 5 iOS >= 7 - number 3,
• iPhone 5 iOS < 7 - number 2,
• iPhone 4, 4S - number 2,
• iPhone 3GS - number 1,
• iPhone 5C and 5S - number 3.

Answer 2

In my experience, this is the case whenever you do not target specifically iOS 7.0 in your Deployment Target as part of your Project/Workspace settings.

Targeting anything other than 7.0 seems to result in this behavior.

To clarify: this value essentially specifies the minimum version of iOS that is allowed to run your app. Specifying iOS 7.0 in this field will restrict use of your app/update to ONLY users with iOS 7.0.
