推荐答案

除非您不愿意搞砸，否则您无法入睡，进入等待状态甚至在UI线程上调用任何冗长的操作.您应该将另一个线程用于此类目的.

我不知道5秒钟后更新标签的目的.您也可以使用计时器，但是最建议使用线程.这取决于您还要做什么.

You cannot sleep, put to wait state and even call any lengthy operation on your UI thread unless you want to screw up things. You should use another thread for purposes like that.

The purpose of updating a label after 5 seconds is unknown to me. You can use timer as well, but thread is the most recommended. It depends what else are your going to do.
