In older versions of the iOS operating system the Control Center button layout was different. The pictures below show you how to lock or unlock portrait orientation on those older versions of the software.
It's super convenient to be able to rotate your screen from portrait to landscape mode automatically, as well as lock it later when you need to. Luckily, both the iPhone's and iPad's screen rotation lock button is easy to access via the Control Panel. With the orientation lock enabled, you can keep your screen from adjusting regardless of whether the device is rotated vertically or horizontally.
To enable portrait orientation mode, go to the Settings app. Go to the Accessibility tab and tap on the Portrait Orientation Lock icon. From there, swipe to the left or right and you will see a new option. Swipe up or down to toggle this setting. You can also go to the General tab to enable the Portrait Mode feature. You can now rotate the screen as desired. You can also change the orientation of your iPhone using the Rotate iPhone 6 feature.
On an iPhone, when you tilt your device on its side, the screen follows and rotates to landscape orientation. Turning on portrait orientation locks the screen so that no matter which way your iPhone is turned, the screen will stay in place. Instead of your iPhone screen flipping between portrait and landscape view, you can use portrait orientation lock.
You can lock the screen orientation on your iPhone or later model of iPad quickly and easily in Control Center. If you have an iPad Pro, iPad Mini 4, or iPad Air 2, or any of the later models, you will be able to lock your iPad screen using portrait orientation in Control Center just like you do on iPhone. To do this:
To lock the screen orientation to an OrientationLockType orientation means that the screen can only be rotated by the user to a specific screen orientation - possibly at the exclusion of other orientations. The possible orientations to which the screen can be rotated is determined by the user agent, a user preference, the operating system's conventions, or the screen itself. For example, locking the orientation to landscape means that the screen can be rotated by the user to landscape-primary and maybe landscape-secondary if the system allows it, but won't change the orientation to portrait-secondary orientation.
User agents might only support a subset of the possible OrientationLockType values. For example, a user agent might not support locking to the \"portrait-secondary\" or \"landscape-secondary\" orientations.
And if you've ever plunked down in bed or on the couch to read something, you've probably discovered that the screen will automatically rotate between portrait and landscape orientations depending on how you hold your phone or tablet. This can be useful, or it can be a huge hassle -- especially if you move around a lot and don't want the screen constantly shifting back and forth.
Step three: While it's still visible, tap that icon to toggle between locked and unlocked settings. When it shows locked, the screen will not rotate from whichever orientation it's currently in. When it shows unlocked, the screen will rotate when you tilt your device. 1e1e36bf2d
