Step by Step guide for upload iPad only apps

Question

Please note that this is not derived from me alone.
This Knowledge is derived from three forum members, DutyFarm, ChoosingNameCanBeSoXXX & Dei_Machiavelli.
I just add the solution for generate the .xcent file.
[Atleast enough for me to make it work.]
Welcome that if anyone find that this step by step guide not detail enough, you can copy and add more points and post again.
Step 1:
Make sure that all the Icons for the iPad are accounted for because if you don't, Application Loader will Scream
[For some strange reason, you have to add the Old iPhone Icon Size as well]:
                         Old iPhone: 57 by 57 [Icon]
             Start Up Icon for iPad: 72 by 72 [Icon-iPad.png].
SpotLight Search for iPad Must Have: 48 by 48 [Icon-iPad-spot.png]
Step 2:
Load the Mac, unzip your *.ipa file, place the *.app file on your desktop and modify its internal Info.plist file.
Change 3.0 to 3.2 here:
<key>MinimumOSVersion</key>
<string>3.2</string>
Step 3:
Because after you change the Info.plist file by your own way, the file will changed to wrong codesign.
So that will need this step to change it back to right codesign which can success upload to apple store.
Create this weird NameOfYourApp.xcent file on your desktop:
That strange 10 digit is the App ID:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>application-identifier</key>
    <string>APP_ID_Letters_&_NUMBER_HERE.com.whatever.YourAppName</string >
    <key>get-task-allow</key>
    <true/>
</dict>
</plist>
Step 4:
Now Type this in Terminal:
/usr/bin/codesign -f -s "iPhone Distribution: Yours Distribution Cert Name" "--resource-rules=/Users/ABC/Desktop/YourAppName.app/ResourceRules.pl ist" --entitlements "/Users/ABC/Desktop/YourAppName.xcent" "/Users/ABC/Desktop/YourAppName.app"
iPhone Distribution: Yours Distribution Cert Name  << This you can check back at your Cert in  Keychain.
/Users/ABC/Desktop/ : here is assume that your username in you Mac OS is ABC. But more easily, you can put all the file at any path you want.
I just put all files at the iPad folder at system disk root. so that the path just /iPad/ .
OK, if no error come out, congrats that you are done. You can upload the app by Application Loader. (Assume that you know what is it, and need to zip you .ipa before upload)
BUT, LIKE ME and some member here, we see two error after the Step 4 command as below:
/Users/kevs/Desktop/MyApp.xcent: unrecognized blob type (accepting blindly)
/Users/kevs/Desktop/MyApp.xcent: invalid length in entitlement blob
After few night try..... finally I found out the solution and just successfully submit the iPad App!!!
The main problem was we used a wrong method to create that stupid MyApp.xcent file!!!!
I used many many method, use Mac text editor, Window notepad, Mac/ Window Dreamweaver as .xml......
but all facing the strange "invalid length in entitlement blob"
why invalid length?!?! so I try to search for what is .xcent..... finally I found the following webpage
http://www.246tnt.com/iPhone/
it's talk about codesign and entitlement files.
then..... I FOUND .xcent NOT ONLY A SAMLPE TEXT FILE!!!!!
in the middle of the link above, there are a highlighted simple script , which is a python script to help us generate a .xcent entitlement file!!!!!
Here is step by step solution to solve this error:
1) just download the .py file here: simple script
2) put the .py file anywhere you like, or just simply put in the root of you mac
3) turn on the Terminal (in /Applications/Utilities), goto the folder where you put the .py
4) TYPE: python gen_entitlements.py 5C297XXXXX.com.yourdomain.MyApp myApp.xcent
    Where 5C297XXXXX.com.yourdomain.MyApp is your AppID with BundleID,
    myApp.xcent is the file will be generate to you
5) Finally you can see the .xcent which make me nearly crazy for a week!!!!!!!!
6) Use this .xcent file to run that codesign script (Step 4 above)
7) Congratulation the codesign changed and you can zip your app and upload it
I have spent many hours for this simple stuff.........so sad........>.<
Hope this post can help all guys who still mad on this error when trying to upload a iPad only apps.
Good luck!!

Answer 1

I think I followed everything very closely, but I am getting these errors when trying to run the codesign script
here is my script command:
/usr/bin/codesign -f -s "iPhone Distribution: Nethercottage Games, LLC" "--resource-rules=/Users/BATC/Desktop/book1.app/ResourceRules.plist" --entitlements "/Users/BATC/Desktop/book1.xcent" "/Users/BATC/Desktop/book1.app"
Here is the error I get:
/Users/BATC/Desktop/book1.app: replacing invalid existing signature
codesign_allocate: object: /Users/BATC/Desktop/book1.app/book1 malformed object (unknown load command 9)
/Users/BATC/Desktop/book1.app: object file format invalid or unsuitable
Any help on this please?
