What would you suggest is the preferred way to add a timer to a
different running thread?
Normally, I would use:
NSRunLoop *runLoop = [NSRunLoop currentRunLoop];
[runLoop addTimer:aTimer forMode:NSDefaultRunLoopMode];
However, this requires that it will be invoked from the context of
the target thread. How do I get the runLoop for any other than the
current thread?
NSRunLoop is not thread safe, so you don't get it. Even is it was
possible, you would not be able to use it.
That said, CFRunLoop is thread safe.
You can retrieve it using -
performSelector:onThread:withObject:waitUntilDone:modes passing a
mutable object as argument (an MutableArray for example) which will be
used to store the return value (your CFRunLoop).
- (void)retrieveCurrentRunLoop:(NSMutableArray *)array {
[array addObject:(id)CFRunLoopGetCurrent()];
}
