initRuntimeSettingsWithFile

Initialize runtime settings with the parameters obtained from a JSON file.

- (void)initRuntimeSettingsWithFile:(NSString* _Nonnull)fileName
                       conflictMode:(EnumConflictMode)conflictMode
                              error:(NSError* _Nullable * _Nullable)error
                              NS_SWIFT_NAME(initRuntimeSettingsWithFile(_:conflictMode:));

Parameters

[in] fileName The settings file path.
[in] conflictMode The parameter setting mode, which decides whether to inherit parameters from previous template settings or to overwrite previous settings with the new template.
[in,out] error Input a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information.
