JBDeviceOwner

Typing names, email addresses, and other personal info is never fun. This is often your user's first experience with your app, and it sucks.

Fortunately, these data often already exist somewhere on your user's phone. JBDeviceOwner presents them to you in a simple interface.

JBDeviceOwner currently gets you the following attributes:

• Name
• Email address
• Phone number

More are coming.

API

JBDeviceOwner *owner = [UIDevice currentDevice].owner;

// owner will be nil if the user's data could not be found.
if (owner != nil) {
  self.firstNameTextField.text = owner.firstName;
  self.lastNameTextField.text  = owner.lastName;
  self.emailTextField.text     = owner.email;
  self.phoneTextField.text     = owner.phone;
}

How does it work?

It's really simple actually.

Most iPhones are named "Jake Boxer's iPhone" (sometimes with a different person's name instead of mine). Most iPhones have their owner saved in their address book.

JBDeviceOwner extracts the owner's name from the device name, finds the matching record in the address book, and populates the JBDeviceOwner instance with the data from the record.
