iCloud Gotchas

Integrating iCloud with core data was easy when I found this tutorial, but I ran into few issues while implementing and testing it on devices. And here are the steps how I managed to solve it.


Issue 1:


The entitlements specified in your application’s Code Signing Entitlements file do not match those specified in your provisioning profile.


(0xE8008016).

If you create a new application Id and enable iCloud then you miss the adventure. It seems enabling iCloud on existing account provide different identifiers for key value store from app identifier.

And editing .entitlements file with Xcode adds some extra identifiers i.e., {APP_IDENFITIER}

Text is an awesome format, don't ruin the beauty with IDE/ plist editors.

Solution to this problem is, copy for key entitlements from your mobile provisioning file and paste the same in place of in your entitlements file.

appname.mobileprovision


appname.entitlements


Issue 2:

2011-11-21 22:57:35.770 appname[6338:1c03] *** -[NSFileManager URLForUbiquityContainerIdentifier:]: An error occurred while getting ubiquity container URL: Error Domain=LibrarianErrorDomain Code=11 "The operation couldn’t be completed. (LibrarianErrorDomain error 11 - The requested container identifier is not permitted by the client's com.apple.developer.ubiquity-container-identifiers entitlement.)" UserInfo=0x1b14b0 {NSDescription=The requested container identifier is not permitted by the client's com.apple.developer.ubiquity-container-identifiers entitlement.}

If you see this issue then your missed to update [nsfilemanager fileManager URLForUbiquityContainerIdentifier:@"with your valid identifier"] in your appdelegate

NSURL *cloudURL = [fileManager URLForUbiquityContainerIdentifier:@"3JCZ6A8BSY.com.yoursite.appname"];

Other common issues are

  • Forgot to turn on wifi when your device is in airplane mode (It beats me every-time)
  • Forgot to switch to your developer certificate from distribution to developer signing (code signing)

Airtel Broadband - How to find bandwidth usage

If you would like to keep tabs on your bandwidth usage?

http://122.160.230.125:8080/gbod/gb_on_demand.do




It is good to know your usage, the 10Gb fair usage plan from Airtel is peanut for my usage as I download a lot of TED & iOS Dev videos from iTunes.

I'm also sick of Airtel as they hijack all my trafic after FUP, even all https are redirected to http (sic).
