下面的代码将帮助您

- (IBAction)showAlert:(id)sender {
    //display the alert
    self.myAlert = [NSAlert alertWithMessageText:@"Sample Test" defaultButton:@"OK" alternateButton:@"DO Nothing" otherButton:@"CANCEL" informativeTextWithFormat:@"TEST",nil];
    [self.myAlert beginSheetModalForWindow:[self window]
                         modalDelegate:self
                        didEndSelector:@selector(errorAlertDidEnd:returnCode:contextInfo:)
                           contextInfo:nil];

    NSArray *buttonArray = [self.myAlert buttons];
    NSLog(@"Button Arrays %@",buttonArray);

    //Close by itself without a mouse click by the user
    //Assuming the Default Button as the Second one "Do Nothing
    NSButton *myBtn = [buttonArray objectAtIndex:2];
    [myBtn performClick:self.myAlert];

}
