MDQuerySetDispatchQueue(_:_:)
Sets the dispatch queue on which query results will be delivered by MDQueryExecute.
Declaration
func MDQuerySetDispatchQueue(_ query: MDQuery!, _ queue: dispatch_queue_t!)Parameters
- query:
The query.
- queue:
The dispatch queue on which results should be delivered.
Discussion
It is not advisable to change set dispatch queue after MDQueryExecute(_:_:) has been called with the query.
Setting the dispatch queue for a synchronous query (kMDQuerySynchronous) has no effect.
