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?
