cancel(forPause:)
Pauses or cancels an encoding job.
Declaration
func cancel(forPause: Bool) -> [AnyHashable : Any]!Parameters
- forPause:
When set to true, pauses an encoding job. When set to false, cancels the job.
Return Value
nil if the extension does not support resuming a job where it left off. Otherwise, it returns a dictionary with attributes defining the extension’s paused state.
Discussion
Implement this method to pause or cancel an encoding job when the Compressor app requests to do so. If the extension supports resuming from a paused state, return the extension’s current state to the Compressor app. If the extension returns nil, an encoding job starts from the beginning when it resumes at a later point.
