我创建了一个应用，可以在用户通过应用界面指定的时间发送每日本地通知。
在测试过程中，我每天安排20次本地通知，以涵盖20天。在最后一天，用户可以点击按钮再安排20个。
当我运行应用程序时，它只发送第一个通知。其余通知永远不会被发送。如何修复代码以使时间增加一天？

您可以设置通知。但请重新考虑您的代码。
像某些功能一样试着像这样使用。我不是只编写代码来帮助您理解 func someFunction() {
for i in 1..<21 {
var notificationR = UILocalNotification()
notificationR = setUpNotification(notificationR)
notificationR.fireDate = Date.init(timeIntervalSinceNow: Double(i))
notificationR = publishLocalNotification(notificationR)
}
}
func setUpNotification(_ notification: UILocalNotification) -> UILocalNotification {
notification.alertBody = "Positive message"
notification.soundName = UILocalNotificationDefaultSoundName
notification.timeZone = TimeZone.current
notification.repeatInterval = NSCalendar.Unit.day
return notification
}
func publishLocalNotification(_ notification: UILocalNotification) -> UILocalNotification {
UIApplication.shared.applicationIconBadgeNumber = 0
UIApplication.shared.scheduleLocalNotification(notification)
return notification
}
