What are the specifications for the icons required by Apple for a custom iPhone application published?
57x57, PNG, No Transparency, No Layers, 72 PPI
512x512, TIFF or JPEG, No Transparency, No Layers, 72 PPI
Note: iPhone OS applies rounded corners, optionally shine, and other effects
Also have a large version of your logo with the name of the application in case Apple contacts you needing a version for marketing purposes.
The icon should be a 57x57 pixel PNG. The PNGs generated by Apple have a PPI of 72.01 so I guess something in that range will work fine. Don't have a very high PPI else images are not rendered properly.
If you want to use a custom icon and not let the iPhone to apply the gloss to your icon, add a key to info.plist called UIPrerenderedIcon (is a boolean value) and make it checked.
When submitting the app to the app store, you will need a 512x512 pixel version of your app's icon (this one in jpeg or tiff format) and at least one screenshot of your app. You can have additional 4 screenshots of the app.
EDIT
Now the specs for icon (to be submitted in iTunes connect) and the app icons have changed. The icon to be submitted to itunesconnect must be 1024x1024 px.
For the app icons, you can find details here - http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/App-RelatedResources/App-RelatedResources.html#//apple_ref/doc/uid/TP40007072-CH6-SW1
Also, make sure the icon files are NON-INTERLACED PNG files. Recently one of our apps' binary was marked invalid since one of the app icon files was an interlaced PNG.
From here:
To ensure that your icon can take advantage of these visual enhancements, provide an image in PNG format that:
Measures 57 x 57 pixels, with 90 degree corners (if the image measures other than this size, iPhone OS scales it)
Does not have any shine or gloss
Name your icon file Icon.png and place it at the top level of your application bundle.
As of May 2012, the official Apple Docs include this chart:
This describes the icons that must be visible in the app. The docs also say the file must be jpeg or png but doesnt specify a dpi.
You must also include a larger copy for the page in iTunes. Again, from the apple docs
full docs available here.
The new retina display is at 114 x 114 for icons.
To submit app to iTunes store you need to have following sizes:
57x57
72x72
114x114
228x228
512x512
Reference: http://ios-funda.blogspot.in/2013/02/all-icon-size-needed-for-app-store.html
The app store is looking for a 512x512 icon as well (not sure the PPI). Best bet is just to design it as vector then you can easily resize and export it as whatever.
This blog post describes all icon sizes and where are they used.
57x57 pixels png... you can choose via code to apply or not the gloss effect.
I made a complete list of the ten (10) needed app icon files in my blog post, iOS App Icons, Listed and Summarized . My information is current as of iOS 3, 4, 5, and 6. Two links take you to the crucial Apple documentation.
I show three tables, each listing the icon files needed for:
Handheld devices (iPhone, iPod touch)
Tablet devices (iPad)
iTunes & App Store
Note: iOS ignores the PPI (Pixels Per Inch) of icon images. You may
author your icon images at any PPI but their width and height, as
measured in pixels, must match the values in the tables below.
This is coming from Apple Technical Q&A QA1686 and contains also information about sizes and files types.

I submitted my app to Apple for the first time. The app is for iPad only and compiled for IOS6.
I got this reply from the submission process :
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
I read this morning that this is quite new. I always have good chance when for my first attempts.
I only used png image files of 72x72, for exemple icon_72.png.
I understand that when I include a retina file, its name becomes icon_72#2x.png
But what about the other resolutions?
How should I name them or how can I manage this ?
Apple mentioned in iOS 7 Human Interface Guidelines
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)
You can name these icons anything you want as long as you use the
CFBundleIcons key to declare the names and you add the #2x suffix to
the names of all high-resolution icons. You can use custom names
because iOS chooses an icon based on whether its size is appropriate
for the intended usage.
If you are a photoshop user, you can download a template here: http://appicontemplate.com
There are photoshop actions included, that will automatically export all the formats you need.
To be on the safe side, use both the iOS 6 and iOS 7 template and include all the resolutions, you have been asked for.
Just to clarify what I did (with some delay, sorry)
As mentioned I added
icon76.png
icon76#2.png
and I modify the myapp-Info.plist adding the new icons in the "icon files" Array
and it ended with :
Item 0 icon72.png
Item 1 icon72#2.png
Item 2 icon76.png
Item 3 icon76#2.png
I also had a small final issue with the png suffix that was capitalised : PNG
So thank you guys : there's always good help here !

I have created my iPhone .png application 'icon' (57x57 with 72 Resolution), however, when I test on my iPhone 4, the image does not appear to cover the entire icon space (a tad small in height) and is a little blurred when compared to the original. Is this because of the high resolution display offered on the iPhone 4? How should I edit my image, so that the device will display a clear and correctly sized icon?
Thanks in Advance,
Jeremy
Create a new icon at 114x114. Call it icon#2x.png and add it to your Resources.
This will use the higher resolution icon for Retina displays.
You can see the full list of recommended icon names and sizes here http://developer.apple.com/library/ios/#qa/qa1686/_index.html
Indeed, you'll have to double the amount of pixels you have: create a 114x114 image and name it Icon#2x.png.
You should have a high quality icon (512x512) already if you plan to release your app on the app store, reducing it's size should work just fine.
I have a few questions about screen resolution, that I'm not clear on. These questions assume they my app will be running on iOS 4.0 and up, and on either iPhone 3GS or iPhone 4.
Should the size of the splash image (default.png) be (960x640) or (480x320)?
Should the size of the app icon (Icon.png) be (57x57) or (114x114)?
What about other graphics that I may use in my app, such a graphic that represents a button? Should I always create these images for the higher resolution, and have the app scale them down? In other words, if I want a button image to be displayed on the 3GS that is 200x40 - should I create the image at 400x80, so that iPhone 4 can take advantage of it?
Thanks!
A good guide to this can be found here: http://mobile.tutsplus.com/tutorials/iphone/preparing-your-iphone-app-for-higher-resolutions/
In general you just create 2 sets of images. Your original and then a new one twice as big with #2x in the name. So for image.png at size 32x32 you would have one that is twice the resolution called image#2x.png at size 64x64. In your app just always use the image.png in Interface Builder and when loading in code.
There is no need to detect the device. These images will automatically be picked up by the OS and subbed in as necessary.
Provide both sizes (960x640 & 480x320) for the splash image using the #2x method described above
Provide both icons (57x57 & 114x114) using the #2x method
For our apps we use a combination of the #2x images and just Scaling the large images. (More information on this can be found in the above article) We use the #2x images for bar buttons, icons, etc. But for UIImageViews we often just use the Scaling. There can be a performance hit for doing this, but for most apps I'd say this is negligible. The savings in file size sometimes make scaling the only option.

You need to provide both if you want them to look nice. For example,
Default.png -> (480x320)

Default#2x.png -> (960x640)
i was currently in to an app development and i have added a launcher screen in JPEG format which is displayed both in simulator and device .. but does it create any problem with apple approval guidelines ?
Update for iOS 8+: you can now use XIB-based launch assets, which is by far the best approach to reduce file size and re-use the same assets for multiple screens sizes. Also, since XIBs support JPG assets, you can always embed JPGs onto XIB files now too!
The Apple documentation pre iOS 8 (now removed), explicitly stated that only PNG is allowed for the launch image:
App Launch (Default) Images
Every app must provide at least one launch image. This image is
typically in a file named Default.png that displays your app’s initial
screen in a portrait orientation. However, you can also provide other
launch images to be used under different launch conditions. All launch
images must be PNG files and must reside in the top level of your
app’s bundle directory. (Avoid using interlaced PNGs.)
I can't speak to how accurate this document is, but it seems they are pretty specific on this point.
My advice: use 8-bit PNG's, and if your files are getting to big, simply don't include the #2x versions for the retina iPad. The 1x version upscales reasonably well on the retina iPad, and better than bloating your app by 5MB+
Yes ofcourse you can use JPEG image in Launch screen or anywhere in project.NO it absolutely does not create any problems in approval process of Apple.So go ahead and code!
Use a png if you can; not only is png artwork better visually, but iOS is optimised for png files.
While it is true Apple won't reject your app for using a jpeg, your users might.
NO you should not use jpgs
Here are apple recomendations
Note: For all images and icons, the PNG format is recommended.
The standard bit depth for icons and images is 24 bits (8 bits each for red, green, and blue), plus an 8-bit alpha channel.
You do not need to constrain your palette to web-safe colors. Although you can use alpha transparency in the icons you create for navigation bars, toolbars, and tab bars, do not use it in application icons.
You can only use PNG files for the launch images. Here is the proof.
Yes , you can choose any one from JPEG/PNG.There is no guidelines from apple to choose type of image.
For more information you can follow apple launch image guidelines.
but I assume that PNGs are more preferable because Apple seems to use PNGs virtually everywhere in iPhone OS.
The iTunes Connect Developer Guide says that the developer must provide a whole bunch of different icon sizes. But I only know from the "normal" app icons (57x57, 114x114) that the device applies the gloss effect and corner rounding automatically.
But how about those other icons? How about the 512x512 iTunesArtwork.png icon? Are the effects applied automatically? Must this icon be shipped inside the bundle of the app? Is there any way to see it "live" how it finally looks, when those effects are applied?
I slightly remember that there was a tool from apple that applied those effects to an icon, so you could see them. Does anyone know more details about this?
The glow and rounded corners are applied automatically. You can control the glow, by adding a key to your Info.plist file: UIPrerenderedIcon set to YES will indicate that your icon is "prerendered" and you don't want the glow.
The AppStore will honor that setting for the 512x512 icon as well.
You actually should supply 6 icons now. One for the iPhone4, iPad, normal iphones/ipod touch, and 2 smaller icons for spotlight search (one is double resolution).
I wrote a pretty cool photoshop script to take you 512px icon and convert it using photoshop into 6 smaller sizes all named correctly.
http://github.com/sponno/iPhone-Photoshop-JSX-Icon-Exporter
You will also see in the header of the file, now to update your info.plist to include all these icons.
For more details on those six icons and their required sizes, here's two great resources:
http://mrgan.tumblr.com/post/708404794/ios-app-icon-sizes
http://blog.cocoia.com/2010/iphone-4-icon-psd-file/
Note that even though the app store honors the UIPrerenderedIcon setting for the icons supplied with your app bundle, the 512x512 icon submitted within iTunesConnect in the app management must not have rounded corners or gloss. If you click the ? next to the icon in iTunesConnect you get this message:
"A large version of your app icon that will be used on the App Store. It must be at least 72 DPI and a minimum of 512 by 512 pixels (it cannot be scaled up). It must be flat artwork without rounded corners."
Why they make it such a p.i.t.a. and make you provide a square icon for this is beyond me. My app icon is rounded with a decorative frame, this square version will look like a**.
