WatchOS警告:从层次结构中删除时拒绝了resignFirstResponder

我在Xcode中遇到此错误。

2018-02-26 07:13:22.326888-0500 Watch Extension[1298:2691330] [View] First responder warning: '<SPInterfacePicker: 0x14dc1740; frame = (76 0; 58 44); gestureRecognizers = <NSArray: 0x14dcd8a0>; layer = <CALayer: 0x14dc1910>>' rejected resignFirstResponder when being removed from hierarchy

我的InterfaceController有4个 WkInterfacePicker 看起来这个错误可能与显示警报有关(当用户保存数据时),但我不确定。

还有人见过这个吗?

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])
    }
}
