You can exit a GCD thread with something like this.
- (void)invalidateQueue
{
_isQueueCanceled = YES;
dispatch_sync(_queue, ^{});
}
- (void)submitWorkToBeDone
{
dispatch_async(_queue, ^{
for ( ... ) {
if (_isQueueCanceled == YES) {
break;
} else {
// do work
}
}
});
}
When invalidateQueue returns the thread has been canceled.
