RE: Thread and sleep

I have tested another way but that will not work either. This is what I did:

I init my lock when my app starts up like this:

lock = [[NSConditionLock alloc] initWithCondition:0];

I wait for the button to be pressed in my second thread like this:

[lock lockWhenCondition:1];
[lock unlockWithCondition:0];

In my worker thread I call this action when I click the button:

- (void)wakeThread:(id)sender
{
[lock lock];
[lock unlockWithCondition:[sender state]];
}

My second thread sleeps until the button is pressed. But not the second
time. Can someone please tell me why?

Peter
