STPCardValidationState

enum STPCardValidationState {}

These fields indicate whether a card field represents a valid value, invalid value, or incomplete value.

  • The field’s contents are valid. For example, a valid, 16-digit card number. Note that valid values may not be complete. For example: a US Zip code can be 5 or 9 digits. A 5-digit code is Valid, but more text could be entered to transition to incomplete again. American Express CVC codes can be 3 or 4 digits and both will be treated as Valid.
