New Icon Dimensions for iOS?

Solar2D iOS
#1

We just uploaded an update to our game.  I receive the following email shortly after upload:

For iOS applications, icons included in the binary submission must be in the PNG format.

  • If your application supports the iPhone device family, you must
    include square icons of the following dimensions: 57x57 pixels and
    120x120 pixels.
  • If your application supports the iPad device family, you must
    include square icons of the following dimensions: 72x72 pixels, 76x76
    pixels and 152x152 pixels

We have in our package :

Icon.png - 57x57

Icon@2x.png - 114x114

Icon-Ipad.png - 72x72

Icon-Ipad@2x.png - 144x144

We have never had an issue before.  Anyone have an idea about these new dimensions?  What is the naming convention for them?

That’s weird, that’s not what it shows here: iOS Human Interface Guidelines

Maybe it’s a new iOS 7 thing?

#3

Yes it is. This is included in the new iOS7 Interface Guidelines from Apple:

This is a copy/paste from the web:

Create different sizes of the app icon for different devices. If you’re creating a universal app, you need to supply app icons in all four sizes.

For iPhone and iPod touch both of these sizes are required:

120 x 120 pixels

60 x 60 pixels (standard resolution)

For iPad, both of these sizes are required:

152 x 152

76 x 76 pixels (standard resolution)

When iOS displays an app icon on the Home screen of a device, it automatically applies a mask that rounds the corners. Make sure your icon has 90° corners so it looks good after the mask is applied.

I’m just wondering how to include them in a Corona Project before making a build. Maybe someone at Corona Labs can clarify this?

Any of you find out anymore information about this? Is it as simple as replace standard Icon/Icon@2x with the new dimensions? I  wonder if we still need to still supply the 57/114, 72/144 and it wouldn’t just downsize them dynamically.

I have games currently running on iOS 7 using the 57/114, 72/144 and got an update through review on friday with the old deminsions. But, yea, i think we should follow it. Did you try submitting it with the same icon names but with the new dimensions only? Meaning remove the old and just use the new strictly?

Edit, nah, don’t do that. The guide says it still needs the old set for iOS 6 and below. What we need is the correct naming conventions for the new iOS 7 icons and just add them to the build.settings file.

@nahmeenstudios thanks for the heads up… I am in the processes of submitting my app to the store as well… 

I named the different files with the new resolutions (Icon-76, Icon-120, etc…)

I just added them under the CFBundleIconFiles in addition to the other Icon files… I will be submitting the app probably tomorrow (Sept 2)… I will report back if I get any e-mails from Apple …

I’m still kinda scratching my head on this one. Let me ask engineering to see if they have figured it out yet.  I saw what appeared to be where someone got rejected already for not having the new icons in place (which makes no sense to me since iOS 7 isn’t out yet).

#7

Found something on 9to5mac that mentions this… http://9to5mac.com/2013/08/30/apple-inadvertently-asking-developers-for-ios-7-optimized-app-icons/

#8

What’s the proper way to include these new sizes in our project?

#9

This is pure speculation and hopefully I’ll  hear back from the engineers after they come back from the long weekend/holiday, but if I were to guess, I would think this would be in order:

                “Icon.png” ,           57x57
                “Icon@2x.png” ,    120x120
                “Icon-72.png” ,      72x72
                “Icon-76.png” ,      76x76
                “Icon-76@2x.png”, 152x152

I honestly don’t think Apple really looks at the file name for anything meaningful.  iOS2 did, but with iOS 3 you provided the file name of the 57x57 using the CFBundleIconFile key.  iOS4 added the array of keys:  CFBundleIconFiles = {.  I suspect that Apple reads the files you specify and actually opens up the file to determine it’s size and hunts for the icons it’s looking for.  If that’s the case, it probably wouldn’t hurt to provide more icons than they will actually use and maybe we should do:

                “Icon.png” ,           57x57
                “Icon@2x.png” ,    114x114

                "Icon-120.png,      120x120

                “Icon-72.png” ,      72x72

                “Icon-72@2x.png”, 144x144
                “Icon-76.png” ,      76x76
                “Icon-76@2x.png”, 152x152

I don’t have any apps that are nearing submission so I don’t have a real good way of testing this right now.  Again DISCLAIMER I’m guessing here, lets wait on the engineers.

(And don’t forget to include the four spotlight icons:  29x29, 58x58, 50x50, 100x100) Of course Apple makes then optional.

Rob, I will give the second set a shot. I think they still want the 57x57 and 114X114 for iOS 6 and below. I should be submitting an update to a app i have in the next week or two, so I will keep this post updated. But I am going with the following  setup.

             “Icon.png”,                 57x57

             “Icon-60.png”,            60X60  – I read somewhere this should be included, its doubtful, but it couldn’t hurt to include

             “Icon@2x.png”,          114x114

             “Icon-120.png”,          120x120

             “Icon-72.png”,            72x72

             “Icon-76.png”,            76x76

            “Icon-72@2x.png”,     144x144

            “Icon-76@2x.png”,     152x152

                       

             “Icon-Small-50.png”,  50x50

            “Icon-Small-50@2x.png”,  100x100

             “Icon-Small.png”,        29x29

             “Icon-Small@2x.png”, 58X58

 @Rob Mircle and @jmarchalonis, I have just submitted an app with the new dimensions last night, in my CFBundle I did some thing similar to what you guys are talking about… http://reviewtimes.shinydevelopment.com is reporting ~4 days from start to finish (I am assuming that number will go up given the holiday), but I will also report if this works… (I used the name Icon-144 instead of Icon-72@2x.png, and so forth…)

#12

I submitted an update on thursday with the naming scheme i mentioned above. I will also let you guys know what the verdict is in a few days. Has iTunes Connect been very unstable for you all recently? It was a nightmare getting it uploaded on thursday and checking things on friday. 

#13

It will be good to know, but after I spent a good amount of time reading through Apples documents you should be fine.

#14

@ Rob I just got a message from Apple; It passed with no issues.

#15

thanks for the infos!

#16

The app I submitted at the beginning of the month passed with no Icon errors…

#17

Thanks to all! Help me a lot this information. My app is under review to.
