AVFoundationErrorDomain错误代码-11819表示AVFoundation不能完成请求操作,可能是由于资源受到限制或暂时不可用。要解决此问题,可以尝试以下步骤:
1.确保设备的存储空间不满,并且网络连接稳定。
2.尝试重新启动应用程序并重新运行操作。
3.如果问题仍然存在,请稍后再尝试,因为这可能是暂时性问题。
示例代码:
func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) { do { try doSomeAction() } catch let error as NSError { if error.domain == AVFoundationErrorDomain && error.code == -11819 { // Handle the error here print("AVFoundation Error: Cannot complete action, try again later.") } else { // Handle other errors print("Error: (error.localizedDescription)") } } }
func doSomeAction() throws { // Perform some action here // If the action cannot be completed due to AVFoundation error -11819, throw the error let error = NSError(domain: AVFoundationErrorDomain, code: -11819, userInfo: [NSLocalizedDescriptionKey: "Cannot complete action", NSLocalizedRecoverySuggestionErrorKey: "Try again later."]) throw error }
