swift – WatchOS警告：从层次结构中删除时拒绝resignFirstRespo

我的InterfaceController有4个WkInterfacePickers,看起来这个错误可能与呈现警报有关(当用户保存数据时),但我不确定.

有没有人见过这个？

我的代码：

if successSaving == true {
    DispatchQueue.main.async {
        WKInterfaceDevice.current().play(.success)
        self.showSuccessAlertWith(message: "Workout Saved,Stats Added.")
    }

    func showSuccessAlertWith(message: String){

        let action1 = WKAlertAction(title: "OK",style: .default) {
            WKInterfaceController.reloadRootPageControllers(withNames: ["InterfaceController"],contexts: nil,orientation: .vertical,pageIndex: 0)
        }
        presentAlert(withTitle: "Success",message: message,preferredStyle: .alert,actions: [action1])
    }
}
