setAssetsFilter(_:)
Sets the filter for the group.
Declaration
func setAssetsFilter(_ filter: ALAssetsFilter!)Parameters
- filter:
The filter for the group.
Discussion
This method sets the filter the group; it does not execute the filter. The filter is applied when you invoke numberOfAssets() or enumerate the contents.
If you don’t set the filter, or set it to nil, the enumeration returns all the assets in the group.
Special Considerations
Only one filter is active at a time. Any enumeration currently in flight continues to completion using the previous filter.
