Question

I am using MGTwitterEngine oAuth and LinkedIn iOS SDK in my iOS application with facebook-ios-sdk

TwitterEngine : https://github.com/bengottlieb/Twitter-OAuth-iPhone

Answer 1

@amit as i have already said EstimateBas64EncodedDataSize this function is define in 2 source file... 1 definition source file is coming from LinkedIn source and 1 definition is coming from file which is source of twitter... you need to search EstimateBas64EncodedDataSize in your project and remove that one out of two particular package in which these function is defined and most probably it is Base64Encoding related files which are added twice in your project makes compiler confuse on which definition to use for that particular function...
