Hi Shiz, okay so i use my iPad plugged into my Macbook. The MacBooks latest update with the "Yosmite" allows you to record any iPad / iPhones screen if it's a trusted Device and Plugged into your computer. (To do this you need the latest update on both your Macbook and your Device you wish to use)
STEPS
1. Plug the device you wish to use into your macbook and if it's not yet a trusted device simply click "yes, trust this device" when asked.
2. Open Quick Time Player and press "File"
3. From their press the "New Movie Recording" button and you'll be greeted with a pleasant screen preparing to record you .
4. From their click the little drop down button to the bottom right of the screen near the record button.
5. You now have the option to use your device, for me it's "Josh's iPad" click that and then your ready to screen record your iPad.
