Here's how you can customize the Control Center settings in iOS 7 to enable or disable Lock Screen access, or access within apps.
1. Go to Settings.
2. Go to Control Center.
3. Toggle the Access On Lock Screen or Access Within Apps switches to the On or Off position.
This can be very useful if you don't want to use Control Center from within apps (you can avoid accidentally swiping up from the bottom). It is also useful to prevent access to the Control Center from the Lock Screen.
