Terminate a process by Cocoa

Question

If I terminate myself, just use the [NSApp terminate: nil], it works very well. But if I want to terminate another process such as the active monitor, what should I do?

To get the list of processes, I use

NSArray* processlist = [[NSWorkspace sharedWorkspace] runningApplications];

Am I right? But how I can terminate a process by Cocoa, not use the kill or KillProcess(<#const ProcessSerialNumber *inProcess#>) or killpd or something like those, I just start learning Cocoa, so maybe I need some simple sample code or some keywords that can help me to find the documents. Thank you for your help.

-[NSWorkspace runningApplications] returns an array of NSRunningApplication objects. NSRunningApplication has a method -[NSRunningApplication terminate]. So if you are looking for a specific application, you could terminate it like this:

-(void)killProcessesNamed:(NSString*)appName
{
    for ( id app in [[NSWorkspace sharedWorkspace] runningApplications] ) 
    {
        if ( [appName isEqualToString:[[app executableURL] lastPathComponent]] ) 
        {
            [app terminate];
        }
    }
}

You could also call forceTerminate to force the app to quit without the normal quitting process. (It won't ask to save changes, etc.)

There are other methods of NSRunningApplication that you can use to make this process simpler depending on whether or not you're searching for a process based on bundle ID or PID.
