无法通过参数传递 Timer.sheduledTimer [重复]

Question

basicPidTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(self.pidsUsage(indexPid:)), userInfo: pidsIndex, repeats: false)

//调用下面的方法但没有触发任何帮助？

@objc func pidsUsage(indexPid : Int){

}

Answer 1

参数的类型必须是Timer。即

@objc func pidsUsage(timer : Timer) {

}
