Write an iPhone application

I want to create a social app from scratch, compatible with iPhone 4 and newer models, running iOS7 or newer. User Permissions: Calendar Contact Location Service Background App Refresh Camera & Mic Camera Roll The app will have the following main functions: **The app should be multilingual ready*** The app aims to become a social media platform with large traffic and user capability. Map integration, users can see their current location and their contacts locations on the map as a pinpoint. The device will start to periodically pull the users’ GPS location data and stop during a specific time (eg. from 5:00pm - 9:00pm), and the location data will be stored within the user’s contact information, which is sharable and accessible by other users’ devices in the same social network. Sign in/up with a variety of social medias (Facebook, Google+ etc). Sign in/up with a custom email address (Plus a way to retrieve forgotten password) Able to send an “invitation” to contacts from other social networks to join the app network if they are not currently using the app. Camera integration, users can take photos with the app, then upload the photo and share among a group of friends. Photos taken can be saved into Camera Roll. All photos uploaded to the server can be automatically deleted from server and user devices. General Information Hierarchy, the app should be able to organise and sort contacts and other information (in ascending/descending/Date/Time etc.) Able to create groups with selected contacts, able to enter Title, Time/Date, and Address and text details for the group.
