Wrong format of screenshots for Apple's app store - png

I want to publish an app to Apple's app store. For this purpose I have to upload some screenshots.
I created three screenshots with the resolutions 1242 x 2208 (iphone) and 2048 x 2732 (ipad). So I have now 6 pictures in png format.
But if I upload one these files I get the error message that the screenshots have the wrong format. What do I wrong?

I would suggest you upload it in png format.

Why my app size more on iphone than the ipa or App Store

I downloaded facebook app on iPhone 6 and its size 99.0 MB on app store but i'm seeing facebook size is 144.0 MB on my iPhone, i didn't find any logic behind it. So please help me Why the app size is increased on iPhone? Any help would be appreciated.
Apps are compressed when you download them. When you have downloaded them, they are uncompressed on your phone.
Therefore you'll see that the App Store states a smaller size, which is the size you have to download - and the phone states a different, larger size, which is the space it takes up on the disk inside the phone.
See for example:
http://en.wikipedia.org/wiki/.ipa_(file_extension)
It states clearly that apps are delivered as .ipa files from the App Store, and that such a file is compressed (zipped).
IPA is a ZIP file, it will unarchive its content on the device.
it also might cache posts/images/...etc general data ,
try installing fresh build ( do not open the app ) and check the size it takes on your device.

Add icon for App Store (required for all apps) to Xcode

I am preparing to submit my application to the Apple App Store and have been researching the requirements for the App Icon. I have filled in all of the allotted slots shown in this picture from Apple's website
However the docs say that a 1024x1024 icon is required for the App Store and I do not see any "slot" for that image in my Xcode project. Where and how do I add that required 1024 x 1024 app icon?
Make a 1024x1024 icon and name it "iTunesArtwork#2x.png" add to assets catalogue.
You can use makeappicon to generate an .xcassets catalogue... makes life easier
(I'm not affiliated with the above)
You will need to log in to Itunes Connect and then go to my apps and scroll down a bit to General App Information.
Using the Asset Catalog as pictured in your example there is no 1024 icon. Normally, for OS X apps the 512pt 2x is the 1024 x 1024 icon. On iOS Apps you must upload a 1024 x 1024 image to iTunes Connect separately from your Asset Catalog that has no transparency. On OSx apps it takes the image from your binary bundle that you uploaded.

Large App icon while submitting to app store is blurred

I am uploading my app to the app store for the first time. I am new at uploading to the app store, too. I noticed that we have to upload a 1024 x 1024 pixels app icon for app store purpose in iTunes Connect. I didn't know about this. I have a 114 x 114 app icon and resized it to 1024 x 1024. After resizing it to this extent it became blurred.
But if I try to upload the same blurred app icon in iTunes Connect, it is accepted and it is looking reasonably good in iTunes Connect. But I don't know how it looks in the app store after submission.
Does Apple reject because of this blurred app icon in iTunes Connect? As the icon is looking good in iTunes Connect, will it look the same in the app store too?
Yes, you can proceed. It will definitely work.

iphone application icon was blur when show on the itunes store

my icon was blur when show on the itunes Store but fine in iphone's locally appstore,my large icon format is:
pixel:512X512
format:png
dpi:72
can anybody point to me what is the reason of icon getting blur in itunes store since i have followed all the spec required by apple alr
Your 512x512 icon should be a jpeg though I can't imagine it being uploaded as iTunes Connect rejects other formats.
Resubmitting is an option.
I found this same problem today. Reading the specs closer I realized they ask for at least a 24 bit .png file. I had uploaded a 8 bit .png file to iTunes Connect. I'm resubmitting today to test but I think this was my problem.

The iTunesArtwork Image: Is this needed every time, or just in Ad-hoc distribution cases?

I am not surfe if I really need every time this 512 x 512 Pixel Icon, since I don't plan to use Ad-hoc distribution. If I get it right, Ad-hoc distribution is the case when you make an App that is supposed to go only on a very few company iPhones, and you dont want anyone to get that app. If that's true, I choose the other distribution type where anyone can get the app. Would I need that image in that case?
Yes, it's for AdHoc distribution where people copy the files into iTunes to allow them to be added to their phone. Technically you don't even need it for AdHoc distribution, if it's not present a default image will be shown in iTunes.
However when submitting to the app store you DO need a 512x512 image which will be shown in the store.
For ad hoc distributions: you can build the 512 x 512 jpeg image into your application as an "iTunesArtwork" resource, and iTunes will display it automatically.
However, there are two important rules to follow:
the image format has to be jpeg
the file name has to be "iTunesArtwork" with no file name extension
When submitting an app to the app store, you upload the 512 x 512 image separately and it does not need to be built into the app as a resource...
Per developer.apple.com:
The iTunes artwork your testers see should be your application’s icon. This artwork must be a 512 x 512 JPEG or PNG file named iTunesArtwork. Note that the file must not have an extension.
This will be an image your testers will see, but nothing your end-users will get in the final build.
