swift – 为什么只调用我的上一个本地通知函数？

// UISwitch用于季度通知

@IBAction func quarterlyFrequencyTapped(_ sender: UISwitch) {

if quarterlyFrequency.isOn == true {

    firstQuarter(); secondQuarter(); thirdQuarter(); fourthQuarter()

    print("quarterly frequency is (quarterlyFrequency.isOn)")

} else {

    removeQuarterlyNotification()

    print("quaterly frequency is (monthlyFrequency.isOn)")

       }

}

//所有四个季度的功能

    let firstQuarterContent = UNMutableNotificationContent()
    firstQuarterContent.title = "First Quarter"
    firstQuarterContent.subtitle = "Some string"
    firstQuarterContent.body = "Some other string"
