Title
Body
I'm building a program that launches another program and is then supposed to monitor it, and take action if it terminates. When the application is launched, I can get an instance of NSRunningApplication from NSWorkspace . Now, the documentation states that NSRunningApplication has the property 'terminated' that is key-value observable. I've tried implementing: [browserInstance addObserver:self forKeyPath:@"terminated" options:NSKeyValueObservingOptionNew context:NULL]; And: - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"observeValueForKeyPath"); if ([keyPath isEqual:@"terminated"]) { NSLog(@"terminated"); } } but I never see the observeValueForKeyPath method get tripped. Does anyone know how to make this work, if it is possible? I haven't been able to find any specific examples anywhere online.
