cocoa - 如何在 cocoa Mac OS X 10.5 中强制终止另一个应用程序

Question

我有这个任务，我需要从我的应用程序杀死另一个我的应用程序，问题是其他应用程序有一个终止确认对话框(没有要保存的关键数据，仅确认用户退出意图)。

• 在 10.6+ 上，您将使用:

  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;
  }
  

• 但是在 <10.6 上，这个常用的 Apple 事件:

  // 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;
  

  无法强制退出!!!

那么你能用什么？

您可以使用我在 cocoabuilder 上挖掘出的这个简单代码:

// 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;
