Overview

The MetaMap class is the main entry point for integrating MetaMap verification into your iOS application. It provides a singleton instance and methods to launch the verification flow with customizable parameters.

​
Properties

​
shared

class var shared: MetaMap { get }

+ (MetaMap * _Nonnull)shared;
The shared singleton instance of MetaMap. Use this property to access the MetaMap functionality throughout your application. Returns: The shared MetaMap instance.

​
Methods

​
showMetaMapFlow

func showMetaMapFlow(
    clientId: String,
    flowId: String?,
    configurationId: String?,
    encryptionConfigurationId: String?,
    metadata: [String: Any]?
)

- (void)showMetaMapFlowWithClientId:(NSString * _Nonnull)clientId 
                             flowId:(NSString * _Nullable)flowId 
                  configurationId:(NSString * _Nullable)configurationId 
       encryptionConfigurationId:(NSString * _Nullable)encryptionConfigurationId 
                           metadata:(NSDictionary<NSString *, id> * _Nullable)metadata;
Launches the MetaMap verification flow with the specified parameters.
​
clientId
String
required
Your MetaMap client ID. This is required to authenticate your application with the MetaMap service.
​
flowId
String
default:"null"
The ID of the specific verification flow to use. If not provided, the default flow will be used.
​
configurationId
String
default:"null"
The ID of the configuration to use for the verification flow.
​
encryptionConfigurationId
String
default:"null"
The ID of the encryption configuration to use for securing verification data.
​
metadata
Dictionary<String, Any>
default:"null"
Additional metadata to pass to the verification flow. This can include:
  • fixedLanguage: Set the SDK language (“en”, “es”, “fr”, “pt”, “ru”, “tr”, “de”, “it”, “pl”, “th”)
  • buttonColor: Customize the button color using hex format
  • buttonTextColor: Customize the button text color using hex format
  • identityId: For re-verification purposes
  • encryptionConfigurationId: Alternative way to set encryption configuration
  • regularFont: Custom regular font file name
  • boldFont: Custom bold font file name
  • Any custom key-value pairs for your integration

​
Usage Examples

​
Swift

import MetaMapSDK

class ViewController: UIViewController {
    
    @objc private func metaMapButtonAction() {
        // Launch MetaMap flow with required parameters
        MetaMap.shared.showMetaMapFlow(
            clientId: "YOUR_CLIENT_ID",
            flowId: "YOUR_FLOW_ID",
            configurationId: nil,
            encryptionConfigurationId: nil,
            metadata: [
                "key1": "value1",
                "key2": 123,
                "fixedLanguage": "en",
                "buttonColor": "#FF5733"
            ]
        )
    }
}

​
Objective-C

#import <MetaMapSDK/MetaMapSDK.h>

@implementation ViewController

- (void)metaMapButtonAction:(UIButton *)sender {
    // Launch MetaMap flow with required parameters
    [MetaMap.shared showMetaMapFlowWithClientId:@"YOUR_CLIENT_ID" 
                                         flowId:@"YOUR_FLOW_ID"
                              configurationId:nil
                   encryptionConfigurationId:nil
                                       metadata:@{
                                           @"key1": @"value1",
                                           @"key2": @123,
                                           @"fixedLanguage": @"en"
                                       }];
}

@end

​
SwiftUI

import SwiftUI
import MetaMapSDK

struct ContentView: View {
    var body: some View {
        Button(action: {
            MetaMap.shared.showMetaMapFlow(
                clientId: "YOUR_CLIENT_ID",
                flowId: "YOUR_FLOW_ID",
                configurationId: nil,
                encryptionConfigurationId: nil,
                metadata: ["key1": "value1", "key2": 123]
            )
        }) {
            Text("Start Verification")
        }
    }
}

​
Notes

  • The MetaMap class uses a singleton pattern. Always access it through the shared property.
  • Make sure to configure the required permissions in your Info.plist file before launching the verification flow.
  • The verification flow will be presented modally on top of the current view controller.
  • Use MetaMapButtonResult.shared.delegate to receive callbacks about the verification status.
