Sign in with a different Apple ID on your iPhone, iPad, or iPod touch - https://support.apple.com/HT203983 - Change iTunes Store account on an iOS device - Log out of your current account with Settings.app > Store (Settings > iTunes & App Stores on iOS 6) > tap on your AppleID. Log in with a different account. Note, turning on automatic downloads or re-download past purchases may tie the device to that account for 90 days (View and remove associated devices in iTunes - https://support.apple.com/HT204074)
