定义变量
public var timerVerify:Timer!
public var verifyButton:UIButton!
public let VERIFY_TIME_EXPIRY = 31
public var timeCount:Int = 31
调用完成获取验证码接口后，启动计时器
public func startVerifyTimer(){
// self.verifyButton.titleLabel?.adjustsFontSizeToFitWidth = true
refreshVerifyBtnDisplay()
timerVerify = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(BaseViewController.refreshVerifyBtnDisplay), userInfo: nil, repeats: true)
}
异步刷新页面按钮的文字
public func refreshVerifyBtnDisplay(){
UIView.performWithoutAnimation({
timeCount = timeCount - 1
if timeCount==0 {
self.verifyButton.isEnabled = true
self.verifyButton.backgroundColor = UIColor.colorWithHexString(hex: "#A80000")
self.verifyButton.setTitle(String.init(format: "send.verify.code".localized()), for: .normal)
self.timerVerify.invalidate()
self.timerVerify = nil
self.timeCount = VERIFY_TIME_EXPIRY
self.verifyCode = ""
}else{
self.verifyButton.isEnabled = false
self.verifyButton.backgroundColor = UIColor.colorWithHexString(hex: "#666666")
self.verifyButton.setTitle(("send.verify.code".localized()+"("+String.init(timeCount)+")"), for: .normal)
}
self.verifyButton.layoutIfNeeded()
})
}
