addResultReceiver

Adds a DSIntermediateResultReceiver object as the receiver of intermediate results.

• Objective-C
• Swift

1. - (BOOL)addResultReceiver:(id<DSIntermediateResultReceiver>)receiver;
   

2. func addResultReceiver(_ receiver: DSIntermediateResultReceiver)
   

Parameters

receiver: A delegate object of DSIntermediateResultReceiver.

Return Value

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

Code Snippet

• Objective-C
• Swift

1. BOOL result = [resultManager addResultReceiver:receiver];
   

2. resultManager.addResultReceiver(receiver)
   

removeResultReceiver

Removes the specified DSIntermediateResultReceiver object.

• Objective-C
• Swift

1. - (BOOL)removeResultReceiver:(id<DSIntermediateResultReceiver>)receiver;
   

2. func removeResultReceiver(_ receiver: DSIntermediateResultReceiver)
   

Parameters

receiver: A delegate object of DSIntermediateResultReceiver.

Return Value

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

Code Snippet

• Objective-C
• Swift

1. result = [resultManager removeResultReceiver:receiver];
   

2. resultManager.removeResultReceiver(receiver)
   

getOriginalImage

Gets the original image data.
