   NSString *appKey = @"Insert your appKey here";
   NSString *secretKey = @"Insert your secretKey here";

1. Open the file RecorderDemo/evalScences/Controller/TestViewController.m.

2. Modify the input parameters according to your needs in the following code block:

   - (void)startSkegn {
   
           ...
          
           [appDic setValue:@"userId" forKey:@"userId"];
           
           NSMutableDictionary *audioDic = [NSMutableDictionary dictionary];
           [audioDic setValue:@"wav" forKey:@"audioType"];
           [audioDic setValue:@16000 forKey:@"sampleRate"];
           [audioDic setValue:@1 forKey:@"channel"];
           [audioDic setValue:@2 forKey:@"sampleBytes"];
           
           NSMutableDictionary *requestDic = [NSMutableDictionary dictionary];
           [requestDic setValue:self.coreType forKey:@"coreType"];
           [requestDic setValue:self.testString forKey:@"refText"];
           
           NSMutableDictionary *paramDic = [NSMutableDictionary dictionary];
           [paramDic setValue:appDic forKey:@"app"];
           [paramDic setValue:audioDic forKey:@"audio"];
           [paramDic setValue:requestDic forKey:@"request"];
           [paramDic setValue:@"native" forKey:@"coreProvideType"];
           NSString *jsonString = [self objectToJsonString:paramDic];
           ...
   }

1. Run the application on your iOS device or simulator.
2. Click on the item on the screen to navigate to the evaluation screen.
