I've tried searching the web, but to no avail. All I've discovered was the traditional way of enabling and disabling auto-rotation by double clicking the home button then swiping left. Then clicking the box with a half circle and lock will turn auto rotation on or off.
See video below for more details.
This guide does not work for my iPhone anymore because all I can see after double-clicking the Home button are just icons and their respective screenshots. The auto-rotation button was gone.

After minutes of experimenting just to solve the issue, I found out that the easiest solution was to use the Control Center. Here's the step-by-step guide on how to enable or disable auto-rotation on iPhone with iOS 7.
Step 1. Go to Settings.
Step 2. Look for the Control Center link.
Step 3. Swipe up from the bottom of the screen to view Control Center.
Step 4. Click the auto-rotation icon (last encircled icon) to turn auto rotation on or off.
This guide possible works also for other devices such as iPad 3, iPad Mini, Iphone 4S, Iphone 4, and other devices using the new Apple OS, the iOS 7.
Instead of going to Control Center in the Settings menu, just swipe up from the bottom of the screen then follow Step 4 above.
