最佳答案
分两步完成。
btn_second: 可以发布一个通知，表明它已被按下，然后返回到“first”。 'first' 收到通知并设置标志。在 viewWillAppear 中，“first”检查标志并在设置后执行“third”segue。
关于ios - NSInvalidArgumentException'，原因 : 'Receiver (<ViewController:>) has no segue with identifier ' ''，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25948880/
