IOS Countdown Set UIButton header title of jitter problem _ios

For example, after sending the verification code, the button state needs to be disable, displaying the countdown time every second, setting only

Or

is not enough, the button will flash a flicker of jitter.

Needs to be set at the same time:

Button.titleLabel.text = title; 

Or

Button.titleLabel.text = title; 
[Button Settitle:title Forstate:uicontrolstatenormal];

The above is a small set to introduce the iOS countdown to the UIButton title of the jitter problem, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
