我正在考虑在数据库中保留所有注册ID(推送令牌)并从iPhone发送通知给用户.我试过这样的事情,但没有得到任何通知.

func sendPNMessage() {
    FIRMessaging.messaging().sendMessage(
        ["body": "hey"], 
        to: TOKEN_ID, 
        withMessageID: "1", 
        timeToLive: 108)  
 } 

我做错了什么或者根本不可能做到这一点？

在iPhone 6 plus上使用ARWorldTrackingSessionConfiguration获取和错误 Unable to run the session, configuration is not supported on this device

它能是什么？

我正在使用ARKit功能,最近的主要iOS版本,但我遇到了错误的崩溃failed assertion

设备不支持MTLRenderPassDescriptor:深度附件的MTLStoreActionMultisampleResolve存储操作

我已经在我的iPhone设备上安装了iOS11测试版.

我正在尝试使用VNImageRequestHandler（iOS Vision）通过相机检测人脸。当我在横向模式下通过相机指向照片时，它会检测到面部，但使用相反的方向模式。

  let detectFaceRequestHandler = VNImageRequestHandler(cvPixelBuffer: pixelBuffer, options: [:])

有来自的问题VNClassificationObservation.

我的目标是识别对象并使用对象名称显示弹出窗口,我能够获得名称,但我无法获得对象坐标或框架.

这是代码:

let handler = VNImageRequestHandler(cvPixelBuffer: pixelBuffer, options: requestOptions)
do {
    try handler.perform([classificationRequest, detectFaceRequest])
} catch {
    print(error)
}

然后我处理

func handleClassification(request: VNRequest, error: Error?) {
      guard let observations = request.results as? [VNClassificationObservation] else {
          fatalError("unexpected result type from VNCoreMLRequest")
      }

    // Filter observation
    let filteredOservations = observations[0...10].filter({ $0.confidence > 0.1 })

    // Update UI
   DispatchQueue.main.async { [weak self] in

    for  observation in filteredOservations {
            print("observation: ",observation.identifier)
            //HERE: I need to display popup with observation name
    } …

更新到新的Google+ sdk后收到错误NSBundle(GPP3PAdditions)gpp_registerFonts] _block_invoke()无法加载字体:Roboto-Regular

如果有人得到了相同的？谢谢

Safari 12.1是否支持服务人员PWA推送通知？我在iOS上尝试了此演示，但仍然对我不起作用。

有机会得到他们吗？谢谢。

我可以问一下hepl吗？尝试从 .responseJSON 获取结果但收到响应失败。

 func performRequest(_ method: HTTPMethod, requestURL: String, params: [String: AnyObject], comletion: @escaping (_ json: AnyObject?) -> Void) {

        Alamofire.request(requestURL, method: .get, parameters: params, encoding: JSONEncoding.default)
          .responseJSON { response in
                print(response)

                if let status = response.response?.statusCode {
                    switch(status){
                    case 201:
                        print("example success")
                    default:
                        print("error with response status: \(status)")
                    }
                }

                print("data:", response.data ?? "no data")  
                print("result:", response.result)

                if let result = response.result.value {
                    let JSON = result as! NSDictionary
                    print("JSON:",JSON)
                    comletion(JSON)
                }
                comletion(nil)

             }
    }
