- (void)perform
{
    NSLog(@"使用自定义连接");
    [self.sourceViewController presentViewController:self.destinationViewController animated:YES completion:nil];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"2vc2"]) {
        ViewController2 *vc2 = (ViewController2 *)[segue destinationViewController];
        vc2.passText = @"使用prepareForSegue:sender进行页面传值";
    }
}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    _recTextView.text = _passText;
}
