I actually have tried this. My code looks like this (is it correct?):
@implementation Worker
- (void)threadMain:(id)data
{
runLoop = [NSRunLoop currentRunLoop];
[runLoop addPort:[NSMachPort port] forMode:NSDefaultRunLoopMode];
while(true)
{
[runLoop run];
}
}
- (void)processRequest:(id)sender
{
NSLog(@"hello");
}
@end
Then from the main thread I send:
[[worker runLoop] performSelector:@selector(processRequest:)
target:worker argument:request order:0 modes:[NSArray
arrayWithObject:NSDefaultRunLoopMode]];
This time the -[NSRunLoop run] method does not exit immediately.
However the problem is that processRequest is never called and the
-[NSRunLoop run] never exits.
What can be wrong? Should it work like this at all?
