NSLocalizedString

Question

我试图用一些局部变量发出通知。在模拟器中，一切正常，没有错误——即使是通知也能正常显示，但如果我在 iPhone 上测试它，应用程序就会崩溃。

    func getContent(fromName: String, andDue: String, andAmount: Double) -> UNMutableNotificationContent {
        let currency = self.appDelegate.settings.getShortCurrency() // standard währung aus dem System holen
        let content = UNMutableNotificationContent()


        content.subtitle = NSLocalizedString("REMINDERTITLE", comment: "Reminder: some payments are overdue...")


    // Error in this line:
    content.body = String.localizedStringWithFormat(NSLocalizedString("REMINDERTEXT", comment: "Hey, %@'s payment from %@ %@ is overdue since %@! Do you want to send him a reminder message?"), fromName, andAmount, currency, andDue)

        content.badge = 1
        content.sound = UNNotificationSound(named: "droppingCoin.wav")

        return content
    }

错误是：

Thread 1: EXC_BAD_ACCESS (code=1, address=0x4084900000000000)

在这一行中：

content.body = String.localizedStringWithFormat(NSLocalizedString("REMINDERTEXT", comment: "Hey, %@'s payment from %@ %@ is overdue since %@! Do you want to send him a reminder message?"), fromName, andAmount, currency, andDue)

注释文本是 .strings 文件中定义的实际本地化文本值。

提前致谢！

您对 andAmount 使用了错误的格式说明符。 andAmount 是一个 double 而不是一个对象，所以使用 %f 而不是 %@。
