class IntermediateResultManager : NSObject
```

## Methods

| Method | Description |
| ------ | ----------- |
| [`addResultReceiver`](#addresultreceiver) | Adds a `DSIntermediateResultReceiver` object as the receiver of intermediate results. |

### addResultReceiver

Adds a [DSIntermediateResultReceiver](intermediate-result-receiver.md) object as the receiver of intermediate results.

>1. 
```objc
- (void)addResultReceiver:(id<DSIntermediateResultReceiver>)receiver;
```
2. 
```swift
func addResultReceiver(_ receiver: IntermediateResultReceiver)
```

**Parameters**

`receiver`: A delegate object of [DSIntermediateResultReceiver](intermediate-result-receiver.md).  

**Return Value**

A `BOOL` value that indicates whether the result receiver is added successfully.

```objc
BOOL result = [resultManager addResultReceiver:receiver];
```
2. 
```swift
resultManager.addResultReceiver(receiver)
```

### removeResultReceiver

```objc
- (void)removeResultReceiver:(id<DSIntermediateResultReceiver>)receiver;
```
2. 
```swift
func removeResultReceiver(_ receiver: IntermediateResultReceiver)
```

**Parameters**

`receiver`: A delegate object of [`DSIntermediateResultReceiver`](intermediate-result-receiver.md).

**Return Value**

A `BOOL` value that indicates whether the result receiver is removed successfully.

```objc
- (DSImageData)getOriginalImage:(NSString)imageHashId;
```
2. 
```swift
func getOriginalImage(_ imageHashId: String) -> DSImageData
```

**Parameters**

`imageHashId`: The image hash ID.

**Return Value**

The original image data as [`DSImageData`]({{ site.dcv_ios_api }}core/basic-structures/image-data.html).
