segue走的话如何给下个界面传值

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    [tableView deselectRowAtIndexPath:indexPathanimated:YES];

     MainModel * model = self.dataSources[indexPath.row];

    [selfperformSegueWithIdentifier:@"ChangeViewController"sender:model.title];

}

- (void)toViewController:(BaseViewController *)viewController sender:(id)sender

{   if ([sender isEqualToString:@"修改密码"]) {

    ((ChangeViewController *)viewController).setType =ChangePassword;

}else{

    ((ChangeViewController *)viewController).setType =ChangePhone;

}

}
