How to force kill another application in cocoa Mac OS X 10.5

问题

I've this task, from my application i need to kill another my application, the problem is that the other application has a Termination Confirm Dialog (there is no critical data to save, only confirmation of user intent to quit).

On 10.6+ you will use:

bool TerminatedAtLeastOne = false;

// For OS X >= 10.6 NSWorkspace has the nifty runningApplications-method.
if ([NSRunningApplication respondsToSelector:@selector(runningApplicationsWithBundleIdentifier:)]) {
    for (NSRunningApplication *app in [NSRunningApplication runningApplicationsWithBundleIdentifier:@"com.company.applicationName"]) {
        [app forceTerminate];
        TerminatedAtLeastOne = true;
    }
    return TerminatedAtLeastOne;
}

but on <10.6 this commonly used Apple Event:

// If that didn‘t work either... then try using the apple event method, also works for OS X < 10.6.
AppleEvent event = {typeNull, nil};
const char *bundleIDString = "com.company.applicationName";

OSStatus result = AEBuildAppleEvent(kCoreEventClass, kAEQuitApplication, typeApplicationBundleID, bundleIDString, strlen(bundleIDString), kAutoGenerateReturnID, kAnyTransactionID, &event, NULL, "");

if (result == noErr) {
    result = AESendMessage(&event, NULL, kAENoReply|kAEAlwaysInteract, kAEDefaultTimeout);
    AEDisposeDesc(&event);
}
return result == noErr;

can't Force Quit!!!

So what can you use?

回答1:

You can use this simple code that I've digged out on cocoabuilder:

// If that didn‘t work then try shoot it in the head, also works for OS X < 10.6.
NSArray *runningApplications = [[NSWorkspace sharedWorkspace] launchedApplications];
NSString *theName;
NSNumber *pid;
for ( NSDictionary *applInfo in runningApplications ) {
    if ( (theName = [applInfo objectForKey:@"NSApplicationName"]) ) {
        if ( (pid = [applInfo objectForKey:@"NSApplicationProcessIdentifier"]) ) {
            //NSLog( @"Process %@ has pid:%@", theName, pid );    //test
            if( [theName isEqualToString:@"applicationName"] ) {
                kill( [pid intValue], SIGKILL );
                TerminatedAtLeastOne = true;
            }
        }
    }
}
return TerminatedAtLeastOne;
