getSimplifiedSettings

Retrieves a SimplifiedCaptureVisionSettings object that contains simplified settings for the specified CaptureVisionTemplate.

  • Objective-C
  • Swift
  1. - (nullable DSSimplifiedCaptureVisionSettings *)getSimplifiedSettings:(NSString *)templateName
                                                            error:(NSError * _Nullable * _Nullable)error;

  2. func getSimplifiedSettings(_ templateName:String) throws -> SimplifiedCaptureVisionSettings

Parameters

templateName: Name of the targeted Capture Vision template that is defined in a JSON string or a JSON file.
error: An NSError pointer. If an error occurs, it will represent the error information.

Error

Error Code Value Description
