#import <MonetaryMobileToken/MonetaryMobileToken.h>

@interface ViewController : UIViewController <MonetaryTokenDelegate>

On Loading:

- (void)tokenLoading
{
  // The framework has begun tokenizing user-input account data.
}

On Success:

- (void)tokenCreated:(MonetaryToken *)token
{
  // A token has been received!
}

In the tokenCreated method, the received MonetaryToken object contains 5 NSString properties:

• Token: The one-time-use token for the user-entered account data.
• Brand: The card brand of account represented by the token.
• ExpirationMonth: The 2-digit expiration month of the account.
• ExpirationYear: The 4-digit expiration year of the account.
• Last4: The last 4 digits of the account number.

On Error:

- (void)tokenizationError:(NSError *)error
{
  // A tokenization error has occurred!
}

The tokenizationError method will receive an NSError object with one of the 4 following error codes:

• MMTConnectionError: Failed to communicate with Monetary Token API.
• MMTAuthenticationError: Public key authentication failed.
• MMTDataValidationError: Failed to tokenize due to invalid account information.
• MMTTokenizationError: An error has occurred tokenizing the account data at the Monetary Token API.

On Cancel:

- (void)tokenizationCancelled
{
  // The user has cancelled tokenization!
}

MonetaryTokenizer *tokenizer = [MonetaryTokenizer new];
[tokenizer requestKeyedTokenWithPublicKey:@"[Public Key Goes Here]"
                              andDelegate:self
                       overViewController:self];
