Name
NSTimer — Mac OS X 10.0
Synopsis
This class represents a timer in the run-loop that can be used to invoke a
method in a target after some elapsed time, or at regularly spaced
intervals. The most straightforward way of creating a time is to use
the method
scheduledTimerWithTime-Interval:target:selector:userInfo:repeats
:,
which creates the timer and add it to the current run-loop in the
default mode. To remove a timer from its run-loop and stopping it
from firing again, send an invalidate
message to
the timer object.
NSTimer
is toll-free bridged with the Core
Foundation type CFRunLoopTimer
. As such,
NSTimer
objects can be used interchangeably with
the CFRunLoopTimer
pointer type,
CFRunLoopTimerRef
.
The timer doesn’t have good resolution; its accuracy is a function of the run-loop and what’s on it.
