CFUserNotificationCreateRunLoopSource(_:_:_:_:)

Declaration

func CFUserNotificationCreateRunLoopSource(_ allocator: CFAllocator!, _ userNotification: CFUserNotification!, _ callout: CFUserNotificationCallBack!, _ order: CFIndex) -> CFRunLoopSource!

Parameters

• allocator:

  The allocator to use to allocate memory for the new object. Pass NULL or kCFAllocatorDefault to use the current default allocator.

• userNotification:

  The user notification to use.

• callout:

  The callback function to invoke when the user notification dialog is dismissed.

• order:

  A priority index indicating the order in which run loop sources are processed. User notifications currently ignore this parameter. Pass 0 for this value.

Return Value

The new CFRunLoopSource object. Ownership follows the The Create Rule.

Discussion

A run loop source needs to be added to a run loop before it can fire and call its callback function. To add the source to a run loop, use CFRunLoopAddSource(_:_:_:).
