Requesting xAuth permission from Twitter API Policy

Twitter API Policy team requires iOS app developer to apply for permission to use xAuth. They suggest me to use oAuth first, but as I'm using MGTwitterEngine, I am unable to use oAuth as c开发者_运维知识库ommunication, except when I use my consumer key & consumer secret .

But using the consumer key & consumer secret , I can only post to my Twitter, instead of allowing users to login with their account.

What have I missed in xAuth application process?

If your application support custom login for twitter, Then you need to mail twitter guys saying that your application support custom login etc,etc feature.

Mail should contain

Consumer key,Secret key etc.

Put the valid reason why you need Xauth key for your application.

Seems iOS 5 has native Twitter support, therefore problem is then solved ( only in iOS 5 ). Still waiting for answers for iOS 4.
