swift – 为什么只调用我的上一个本地通知函数？

概述我对 swift很新,我正在尝试调用多个函数来请求UISwitch IBAction中的本地通知.我想在某个日期发送通知 – 一年中的每个季度在第4,7,10,1个月.只有第四季度功能被调用.如何调用所有四个函数？这是我的代码： // UISwitch用于季度通知 @IBAction func quarterlyFrequencyTapped(_ sender: UISwitch) {if q 我对 swift很新,我正在尝试调用多个函数来请求UISwitch IBAction中的本地通知.我想在某个日期发送通知 – 一年中的每个季度在第4,7,10,1个月.只有第四季度功能被调用.如何调用所有四个函数？这是我的代码：

// 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

解决方法 我认为你在iOS10上,你正在使用UserNotifications框架吗？

您的标识符很可能具有相同的标识符,并且每个标识符都会更新以前的通知.

原因标识符用于帮助您更新具有相同标识符的先前通知.例如,您发送通知以将分数从0-0更新为0-1.而不是在屏幕上有2个通知,你现在只有一个.

您的修复是为每个使用不同的标识符.

编辑后更新：正如我所说的……所有通知都以“季度”作为标识符.给他们每个人一个单独的名字.
