cancelling queued performSelector:afterDelay calls
[NSObject cancelPreviousPerformRequestsWithTarget:]or
[NSObject cancelPreviousPerformRequestsWithTarget:selector:object:]The target is the original object on which performSelector:afterDelay: was called.
For example:
// schedule the selector[self performSelector:@selector(mySel:) withObject:nil afterDelay:5.0];// cancel the above call (and any others on self)[NSObject cancelPreviousPerformRequestsWithTarget:self];See apple docs, it's right at the end of the performSelector:withObject:afterDelay: description.
In order to cancel all previous perform requests, you may use :
[NSObject cancelPreviousPerformRequestsWithTarget:self];
If you are looking for "performSelector" to have its matching "cancelPreviousPerformSelector"... it doesn't. (Ugh, Apple, why do you do that to me???)
The, er, ah, "matching" methods are:
performSelectorcancelPreviousPerformRequestsWithTarget(Just to make it extra hard to remember, without searching the docs.)
