Question

我正在尝试修复每天显示的通知，我应该在第二天为学校收拾什么。

一切似乎都没问题，但content.subtitle显示错误：

主题1：EXC_BREAKPOINT（代码= 1，子代码= 0x1007dbb00）

阵列也有问题吗？我搜索了答案，但看起来没有人使用数组通知机构。它甚至可能吗？如果不是，我可以用更好的替代品替换它吗？谢谢你的帮助。

let plan = [
    ["dzien": "Sunday", "lekcje": nil],
    ["dzien": "Saturday", "lekcje":["pon1","pon2","pon3"]],
    ["dzien": "Tuesday", "lekcje":["wt1","wt2","wt3"]],
    ["dzien": "Wednesday", "lekcje":["sr1","sr2","sr3"]],
    ["dzien": "Thursday", "lekcje":["cz1","cz2","cz3"]],
    ["dzien": "Friday", "lekcje":["pt1","pt2","pt3"]],
    ["dzien": "Saturday", "lekcje": nil],
]

func getDayOfWeek() -> Int {
    let myCalendar = Calendar(identifier: .gregorian)
    let weekDay = myCalendar.component(.weekday, from: Date())
    return weekDay - 1
}

    @objc func registerLocal() {
    let center = UNUserNotificationCenter.current()

    center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
        if granted {
            print("Sukces")
        } else {
            print("Nie dzieła")
        }
    }
}

    @objc func scheduleLocal() {
        let center = UNUserNotificationCenter.current()

        let content = UNMutableNotificationContent()

        let d = getDayOfWeek()%6
        let dzis = plan[d]
        if dzis["lekcje"] != nil {

        content.title = "Pack up"
        content.subtitle = dzis["dzien"]
        var lekcje = ""
        for lekcja in dzis["lekcje"] {
            lekcje+="\(lekcja)\n"
        }
        content.body = lekcje
        content.userInfo = ["customData": "fizzbuzz"]
        } else {

        content.title = "Tommorow \(dzis["dzien"]), You don't have any subjects."
        }

        var dateComponents = DateComponents()
        dateComponents.hour = 16
        dateComponents.minute = 00
        let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

        let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
        center.add(request)

            }
}

问题是编译器将plans的类型推断为[String:Any]，当您尝试content.subtitle = dzis["dzien"]时，dzis["dzien"]的类型为Any而不是String。

为了工作，您必须将其强制转换为String。

guard let subtitle = dzis["dzien"] as? String else {return}
content.subtitle = subtitle
