Read the protected tweets by using application



I have been developing the iOS app that allows user to get the tweets from the app owner. Because the app owner wants these tweets are displayed in the app only, not be public, so I have created an application from my twitter dev account, then use the provided API key and API secret to access the tweet.

The problem is the app owner’s twitter account is set as protected mode, means only followers can read the tweets, not public. Do you guys know how to grant the permission to the application to read the public timeline?
