How to Change the Apple ID on iPhone, iPod Touch & iPad
Your Apple ID is a unique identifier used in multiple services and apps across the Apple ecosystem, like iTunes and the App Store, where your ID is tied to your purchases and downloads. There are occasions upon which you might want to change your Apple ID on iPhone, or swap it for another ID, to be precise. Some downloads are only available in certain geographic App Store regions, which can be circumvented by registering multiple Apple ID accounts and logging into either one of them at a time. This guide will show you how to change the currently logged-in Apple ID directly on your iPhone.
Note that your iCloud login can be different from your Apple ID and iTunes & App Store login, which is tied to Apple ID. Those are handled separately by iOS and can be managed independently. Logging out of your Apple ID with regards to the App Store does not mean that your iCloud mail account is signed out, too.

Multiple Apple IDs: What to expect
Signing out of your Apple ID and logging in with another does not make your apps disappear, don’t worry. All of your content stays put on your device, the only thing to keep in mind is that features such as iTunes Match are bound to your Apple ID. As soon as you log out, the feature is disabled temporarily.
Note that apps which you bought and downloaded while logged into one account, will ask for the login credentials when they are to be updated. This can be quite a hassle, so make sure to remember which of your accounts is primarily used for downloading or buying iOS apps. Other than that, you shouldn’t run into any trouble.
