Convert screens to Native Xcode and implement FB functionality as spoken.
Take in mind the following things;
1) It should made easy to localise both screens! So please no image buttons or if there is no other choice, please allow a different button to be displayed per language.
2) The images used by in the signup screen should be taken apart from the rectangle containing the FB controls and so on; the background image will be replaced before the app is released! Also the logo should be a separate object/control since it is currently redesigned and either the app name will change!
3) For now the only feature of FB API that will be implemented is the FB Login. People can only signup using Facebook!
4) The created UI should work on iPhone & iPad
5) Compatible with IOS 8 & 9
