Yes, you need to add a 120x120 high resolution icon. Now, if you want to target only iOS 7, you just need 76 x 76, 120 x 120 and 152 x 152 icon sizes. If you also want to target iOS 6, you’ll need

57 x 57, 72 x 72, 76 x 76, 114 x 114, 120 x 120, 144 x 144 and 152 x 152

icon sizes. Without counting Spotlight and Settings icon if you don’t want the OS to interpolate them!





As per the blog post New Metrics for iOS 7 App Icons.

UPDATE:

As per Apple Guideline App-icon OR Icon and Image Sizes:

Icon dimensions (iOS 7 and later)



Icon dimensions (iOS 6.1 and earlier)




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)

Now set this into Project:

Create a new icon with 120 pixels with high-resolution and 60 pixels as regular as above that the Apple documentation mentions and set the name. For example,

icon-120.png

and

icon-152.png

.

Put this icons into your project Resource folder and add this icon into the project:



After this, click on

ProjectName-Info.plist

and find the icon files row. If you can't find it, then add it by clicking the

(+)

sign and select icon files and then set all icon images like below.





Now archive and distribute your project as we did for submission of the app binary into the App Store. I hope now you can submit your app without any icon issue.

NOTE:-

Be careful to provide all the icons you need. Otherwise your app will not pass Apple validation. If you’ve received this kind of email:

[code]Invalid Image - 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

Xcode 5 app icon Manage

If you are using xCode5 The first thing to update is the icons. Xcode 5 introduces Asset Catalogs to simply managing multiple copies of an image (such as for multiple resolutions). We’ll create one to manage both the Game’s icons, along with the Launch Images.



Now, click the Use Asset Catalog button. When confirming the migration, you’re also asked if you wish to migrate the Launch Images (which is iOS talk for the splash screen that appears when starting your app) - you’ll want to ensure this is checked as well.



Please take a Look for more Info Apple doc of Asset Catalogs
