iOS 7 App Icons Launch images And Naming Convention While Keeping iOS 6 Icons

Question

I just finished an app on iOS 6 and bought a developer account a week ago so haven t had much time playing with the iOS 7 SDK  Just downloaded the Golden Master version and trying to upgrade my app to be compatible with iOS 7   I realised that iOS 7 requires a little work with app icons  I have checked many related question and i am confused what to do  I already have an iOS 6 app with app icons and when i installed the golden master version i saw the following     and for launch images     I can create new flat icons for iOS 7 while i want iOS users to keep seeing the old ones   What should i do  Use the  Use Asset Catalog  or add the icons manually and if i am adding the icons manually then what should i name these images  Thanks

You should use Asset Catalog   I have investigated  how we can use Asset Catalog  Now it seems to be easy for me  I want to show you steps to add icons and splash in asset catalog   Note  No need to make any entry in info plist file    And no any other configuration   In below image  at right side  you will see highlighted area  where you can mention which icons you need  In case of mine  i have selected first four checkboxes  As its for my app requirements  You can select choices according to your requirements     Now  see below image  As you will select any App icon then you will see its detail at right side selected area  It will help you to upload correct resolution icon    If Correct resolution image will not be added then following warning will come  Just upload the image with correct resolution    After uploading all required dimensions  you shouldn t get any warning

Absolutely Asset Catalog is you answer  it removes the need to follow naming conventions when you are adding or updating your app icons   Below are the steps to Migrating an App Icon Set or Launch Image Set From Apple   1- In the project navigator  select your target   2- Select the General pane  and scroll to the App Icons section     3- Specify an image in the App Icon table by clicking the folder icon on the right side of the image row and selecting the image file in the dialog that appears     4-Migrate the images in the App Icon table to an asset catalog by clicking the Use Asset Catalog button  selecting an asset catalog from the popup menu  and clicking the Migrate button     Alternatively  you can create an empty app icon set by choosing Editor   New App Icon  and add images to the set by dragging them from the Finder or by choosing Editor   Import

In case you do not want to use Asset Catalog  you can add an iOS 7 icon for an old app by creating a 120x120  png image  Name it Icon-120 png and drag in to the project    Under TARGET   Your App   Info   Icon files  add one more entry in the Target Properties     I tested on Xcode 5 and an app was submitted without the missing retina icon warning

Okay adding to  null s awesome post about using the Asset Catalog   You may need to do the following to get the App s Icon linked and working for Ad-Hoc distributions   production to be seen in Organiser  Test flight and possibly unknown AppStore locations     After creating the Asset Catalog  take note of the name of the Launch Images and App Icon names listed in the  xassets in Xcode   By Default this should be    AppIcon LaunchImage    To see this click on your  xassets folder icon in Xcode    this can be changed  so just take note of this variable for later      What is created now each build is the following data structures in your  app   For App Icons   iPhone   AppIcon57x57 png  iPhone non retina   Notice the Icon name prefix  AppIcon57x57 2x png  iPhone retina    And the same format for each of the other icon resolutions   iPad   AppIcon72x72 ipad png  iPad non retina   AppIcon72x72 2x ipad png  iPad retina     For iPad it is slightly different postfix     Main Problem  Now I noticed that in my Info plist in Xcode 5 0 1 it automatically attempted and failed to create a key for  Icon files  iOS 5   after completing the creation of the Asset Catalog   If it did create a reference successfully   this may have been patched by Apple or just worked  then  all you have to do is review the image names to validate the format listed above   Final Solution   Add the following key to you main  plist  I suggest you open your main  plist with a external text editor such as TextWrangler rather than in Xcode to copy and paste the following key in    lt key gt CFBundleIcons lt  key gt   lt dict gt       lt key gt CFBundlePrimaryIcon lt  key gt       lt dict gt           lt key gt CFBundleIconFiles lt  key gt           lt array gt               lt string gt AppIcon57x57 png lt  string gt               lt string gt AppIcon57x57 2x png lt  string gt               lt string gt AppIcon72x72 ipad png lt  string gt               lt string gt AppIcon72x72 2x ipad png lt  string gt           lt  array gt       lt  dict gt   lt  dict gt    Please Note I have only included my example resolutions  you will need to add them all     If you want to add this Key in Xcode without an external editor  Use the following    Icon files  iOS 5  - Dictionary Primary Icon - Dictionary Icon files - Array Item 0 - String   AppIcon57x57 png And for each other item   app icon      Now when you finally archive your project the final  xcarchive payload  plist will now include the above stated icon locations to build and use   Do not add the following to any  plist  Just an example of what Xcode will now generate for your final payload   lt key gt IconPaths lt  key gt   lt array gt       lt string gt Applications Example app AppIcon57x57 png lt  string gt       lt string gt Applications Example app AppIcon57x57 2x png lt  string gt       lt string gt Applications Example app AppIcon72x72 ipad png lt  string gt       lt string gt Applications Example app AppIcon72x72 2x ipad png lt  string gt   lt  array gt
