NSLocalizedString-線程1：具有String.localizedStringWithFormat的EXEC_BAD_ACCESS

Question

我試圖用一些局部變量發出通知。 在模擬器中，一切正常，沒有錯誤-通知也按預期顯示，但如果我在iPhone上進行測試，則應用程序將崩潰。

    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
    }

錯誤是：

線程1：EXC_BAD_ACCESS（代碼= 1，地址= 0x4084900000000000）

在這一行：

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)

注釋文本是在.strings文件中定義的實際本地化文本值。

提前致謝！

您為andAmount使用了錯誤的格式說明符。 andAmount是一個double而不是一個對象，因此請使用％f而不是％@。
