limitDate(forMode:)
Performs one pass through the run loop in the specified mode and returns the date at which the next timer is scheduled to fire.
Declaration
func limitDate(forMode mode: RunLoop.Mode) -> Date?Parameters
- mode:
The run loop mode to search. You may specify custom modes or use one of the modes listed in
Run Loop Modes.
Return Value
The date at which the next timer is scheduled to fire, or nil if there are no input sources for this mode.
Discussion
The run loop is entered with an immediate timeout, so the run loop does not block, waiting for input, if no input sources need processing.
