AWFDataAnimationDelegate

Objective-C

@protocol AWFDataAnimationDelegate <AWFAnimationDelegate>

Swift

protocol AWFDataAnimationDelegate : AWFAnimationDelegate

The AWFDataAnimationDelegate protocol defines a set of optional methods that can be used to be notified when the point data animation data changes.


                    
                    
                    -animation:didAddDataObjects:

Tells the delegate the animation has data objects to be added for the current position in the timeline. * Typically this is used by a AWFWeatherMap instance to be notified when data objects should be added to the map. *

Declaration

Objective-C

- (void)animation:(nonnull AWFDataAnimation *)animation
    didAddDataObjects:(nonnull NSArray<id<AWFDataRepresentable>> *)objects;

Swift

optional func animation(_ animation: AWFDataAnimation, didAddDataObjects objects: [AWFDataRepresentable])

Parameters

`animation`	The animation that added data objects.
`objects`	The data objects that are active for the current timeline range.


                    
                    
                    -animation:didRemoveDataObjects:

Tells the delegate the animation has data objects to be removed for the current position in the timeline. * Typically this is used by a AWFWeatherMap instance to be notified when data objects should be removed from the map. *

Declaration

Objective-C

- (void)animation:(nonnull AWFDataAnimation *)animation
    didRemoveDataObjects:(nonnull NSArray<id<AWFDataRepresentable>> *)objects;

Swift

optional func animation(_ animation: AWFDataAnimation, didRemoveDataObjects objects: [AWFDataRepresentable])

Parameters

`animation`	The animation managing the data objects.
`objects`	The data objects that are inactive for the current timeline range.
