# simpl-fingerprint-sdk-ios


## How to install

### CocoaPods :
[CocoaPods](https://cocoapods.org/) is a dependency manager for Cocoa projects. You can install it with the following command:

 ````
 $ gem install cocoapods
 ````
To integrate GetSimpl into your Xcode project using CocoaPods, specify it in your Podfile:

 ````
 pod 'SimplFingerPrint'
 ````

Then, run the following command:

 ````
 $ pod install
 ````

## Usage

* Import the Library :

   Obj-C

	````
	#import <SimplFingerPrint/SimplFingerPrint.h>
	````
  Swift

	````
	import SimplFingerPrint
	````

* Create a GSUser Object :

   Obj-C

    ````
    GSUser *user = [[GSUser alloc] initWithPhoneNumber:@"user mobile number" email:@"user email"]
    ````
   Swift

   ````
   let user = GSUser(phoneNumber: "user mobile number" , email: "user email" )
   ````

 * If you want to pass extra params , create a dictionary with params and pass it to GSUser object created above :

   Obj-C

   ````
    NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
    params[@"user_location"] = @"18.9750,72.8258"
    params[@"transaction_amount_in_paise"] = @"123344"
    user.headerParams = parms
   ````

   Swift

   ````
   var params : [String : Any] = [:]
   params["user_location"] = "18.9750,72.8258"
   params["transaction_amount_in_paise"] = "123344"
   user.headerParams = parms
   ````

  * Collect the encrypted fingerprint :

   Obj-C

   ````
    GSFingerPrint *fp = [[GSFingerPrint alloc] initWithMerchantId:@"Your merchant id" andUser:user];
    [fp generateEncryptedPayloadWithCallback:^(NSString *payload) {
        NSLog(@"Payload: %@", payload);
    }];
   ````
   Swift

   ````
    let fp = GSFingerPrint(merchantId: "Your merchant id", andUser: user)
    fp.generateEncryptedPayload { (payload: String?) in
      print(payload)
    }
   ````

  Note that the payload will be AES (AES/CBC/PKCS7Padding) encrypted.
