How to specify size for iPhone 6/7 customised edge-to-edge image?

Question

Say I want a bundled image to take up all available screen width in an iPhone app - for example a banner. I\'d create my_banner.png with width 320px

Answer 1

I am using the following trick as some stuff actually works:

• Asset Catalog for specific devices
• Specify images for 1x, 2x on the base of 320x640
• Specify images for 4 2x and 3x on the base of 320x568 (iPhone 5)
• Create a new Images set for the iPhone 6 specifically (as this is the only device that makes trouble with edge to edge bindings)
• Only provide 2x image for iPhone 6 in full resolution (750x1334)

Declare a constant

#define IS_IPHONE_6 [[UIScreen mainScreen]nativeBounds].size.width == 750.0 ? true : false

and use it like this:

UIImage *image = [UIImage imageNamed:@"Default_Image_Name"];
if(IS_IPHONE_^) {
    image = [UIImage imageNamed:@"Iphone6_Image_Name"];
}

this might be not the most beautiful solution, but it works, at least as long as apple does not provide a better API for edge to edge bindings.
