swift - 为什么只调用我的最后一个本地通知函数?

我是 swift 的新手,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 - 一年中每个季度的第 4、7、10、1 个月。只有第四季度的函数被调用。我怎样才能调用所有四个函数?这是我的代码:

//用于季度通知的 UISwitch

@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

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

var firstQuarterDate = DateComponents()
firstQuarterDate.month = 3
firstQuarterDate.day = 11
firstQuarterDate.hour = 19
firstQuarterDate.minute = 20

let firstQuarterTrigger = UNCalendarNotificationTrigger(dateMatching: firstQuarterDate, repeats: true)
let firstQuarterRequestIdentifier = "Quarterly"
let firstQuarterRequest = UNNotificationRequest(identifier: firstQuarterRequestIdentifier, content: firstQuarterContent, trigger: firstQuarterTrigger)
UNUserNotificationCenter.current().add(firstQuarterRequest, withCompletionHandler: nil)
}

func secondQuarter() {
let secondQuarterContent = UNMutableNotificationContent()
secondQuarterContent.title = "Second Quarter"
secondQuarterContent.subtitle = "Some string"
secondQuarterContent.body = "Some other string"

var secondQuarterDate = DateComponents()
secondQuarterDate.month = 3
secondQuarterDate.day = 11
secondQuarterDate.hour = 19
secondQuarterDate.minute = 21

let secondQuarterTrigger = UNCalendarNotificationTrigger(dateMatching: secondQuarterDate, repeats: true)
let secondQuarterRequestIdentifier = "Quarterly"
let secondQuarterRequest = UNNotificationRequest(identifier: secondQuarterRequestIdentifier, content: secondQuarterContent, trigger: secondQuarterTrigger)
UNUserNotificationCenter.current().add(secondQuarterRequest, withCompletionHandler: nil)
}

func thirdQuarter() {
let thirdQuarterContent = UNMutableNotificationContent()
thirdQuarterContent.title = "Third Quarter"
thirdQuarterContent.subtitle = "Some string"
thirdQuarterContent.body = "Some other string"

var thirdQuarterDate = DateComponents()
thirdQuarterDate.month = 3
thirdQuarterDate.day = 11
thirdQuarterDate.hour = 19
thirdQuarterDate.minute = 22

let thirdQuarterTrigger = UNCalendarNotificationTrigger(dateMatching: thirdQuarterDate, repeats: true)
let thirdQuarterRequestIdentifier = "Quarterly"
let thirdQuarterRequest = UNNotificationRequest(identifier: thirdQuarterRequestIdentifier, content: thirdQuarterContent, trigger: thirdQuarterTrigger)
UNUserNotificationCenter.current().add(thirdQuarterRequest, withCompletionHandler: nil)
}

func fourthQuarter() {
let fourthQuarterContent = UNMutableNotificationContent()
fourthQuarterContent.title = "Fourth Quarter"
fourthQuarterContent.subtitle = "Some string"
fourthQuarterContent.body = "Some other string"

var fourthQuarterDate = DateComponents()
fourthQuarterDate.month = 3
fourthQuarterDate.day = 11
fourthQuarterDate.hour = 19
fourthQuarterDate.minute = 23

let fourthQuarterTrigger = UNCalendarNotificationTrigger(dateMatching: fourthQuarterDate, repeats: true)
//let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: true)
let fourthQuarterRequestIdentifier = "Quarterly"
let fourthQuarterRequest = UNNotificationRequest(identifier: fourthQuarterRequestIdentifier, content: fourthQuarterContent, trigger: fourthQuarterTrigger)
UNUserNotificationCenter.current().add(fourthQuarterRequest, withCompletionHandler: nil)
}

最佳答案

我认为您使用的是 +iOS10,并且您正在使用 UserNotifications 框架,对吗?

很可能您的标识符具有相同并且每个都是UPDATING之前的通知。

identifier 存在的原因是为了帮助您更新以前具有相同标识符的通知。例如,您发送通知将比分从 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。

您的解决方法是为每个使用不同标识符。

编辑后更新:就像我说的...您所有的通知都有 "Quarterly" 作为它们的标识符。给他们每个人一个单独的名字。
