User Profile

I am using the sdk from OneSignal. Let's assume, I have following use case:User A use my app in German language. He triggers an action within the app e. g. a like on an image of User B. User B gets a push notification about the like. But User B uses the app in English language. How can I achieve that?I mean, I can send the notification message in a particular language but if User B decides to change the language of the mobile device to Turkish, then I have to be flexibel.Is there any way, I can access the incoming push notification on the target device?Currently, my code for sending the notification from the source device looks like this:public func notifyAboutSubscription(userObject:User, receiverArray:[String]) { var receiverArray = removeChallengeCreatorTokenFromArray(receiverArray: receiverArray) notificationTypeService.clearReceiverListForNotificationType(completionHandler: { (clearedReceiverArray) in receiverArray = clearedReceiverArray let source = self.determineUserType(userObject: userObject) OneSignal.postNotification(["contents": ["en": source + NSLocalizedString(FOLLOW_MESSAGE, comment: "")], "include_player_ids": receiverArray]) }, receiverList: receiverArray, notificationType: NotificationType.follow) }I am thankful for any hintsBest regards,Nazar Medeiros

Hello experts,I want to create a small image modification app. Purpose is to replace a certain pixel color with another one by including a specific tolcerance value.The concrete 'Replace color' functionality looks like following: func replaceColor(color:SKColor, withColor:SKColor, image:UIImage, tolerance:CGFloat, alpha:CGFloat) -> UIImage{ var result = UIImage() // This function expects to get source color(color which is supposed to be replaced) // and target color in RGBA color space, hence we expect to get 4 color components: r, g, b, a assert(color.cgColor.numberOfComponents == 4 && withColor.cgColor.numberOfComponents == 4, "Must be RGBA colorspace") // Allocate bitmap in memory with the same width and size as source image let imageRef = image.cgImage let width = imageRef?.width let height = imageRef?.height let colorSpace = CGColorSpace(name: CGColorSpace.sRGB)! let bytesPerPixel = 4 let bytesPerRow = bytesPerPixel * width!; let bitsPerComponent = 8 let bitmapByteCount = bytesPerRow * height! let rawData = UnsafeMutablePointer.allocate(capacity: bitmapByteCount) let context = CGContext(data: rawData, width: width!, height: height!, bitsPerComponent: bitsPerComponent, bytesPerRow: bytesPerRow, space: colorSpace, bitmapInfo: CGImageAlphaInfo.premultipliedLast.rawValue | CGBitmapInfo.byteOrder32Big.rawValue) let rc = CGRect(x: 0, y: 0, width: width!, height: height!) // Draw source image on created context context?.draw(imageRef!, in: rc) // Get color components from replacement color let withColorComponents = withColor.cgColor.components let r2 = UInt8(withColorComponents![0] * 255) let g2 = UInt8(withColorComponents![1] * 255) let b2 = UInt8(withColorComponents![2] * 255) let a2 = UInt8(withColorComponents![3] * 255) // Prepare to iterate over image pixels var byteIndex = 0 while byteIndex < bitmapByteCount { // Get color of current pixel let red:CGFloat = CGFloat(rawData[byteIndex + 0])/255 let green:CGFloat = CGFloat(rawData[byteIndex + 1])/255 let blue:CGFloat = CGFloat(rawData[byteIndex + 2])/255 let alpha:CGFloat = CGFloat(rawData[byteIndex + 3])/255 let currentColor = SKColor(red: red, green: green, blue: blue, alpha: alpha); // Compare two colors using given tolerance value if self.compareColor(color: color, withColor: currentColor , withTolerance: tolerance) { // If the're 'similar', then replace pixel color with given target color rawData[byteIndex + 0] = r2 rawData[byteIndex + 1] = g2 rawData[byteIndex + 2] = b2 rawData[byteIndex + 3] = a2 } byteIndex = byteIndex + 4; } // Retrieve image from memory context let imgref = context!.makeImage() result = UIImage(cgImage: imgref!) // Clean up a bit rawData.deinitialize() return result } func compareColor(color:SKColor, withColor:SKColor, withTolerance:CGFloat) -> Bool { var r1: CGFloat = 0.0, g1: CGFloat = 0.0, b1: CGFloat = 0.0, a1: CGFloat = 0.0; var r2: CGFloat = 0.0, g2: CGFloat = 0.0, b2: CGFloat = 0.0, a2: CGFloat = 0.0; color.getRed(&r1, green: &g1, blue: &b1, alpha: &a1); withColor.getRed(&r2, green: &g2, blue: &b2, alpha: &a2); return fabs(r1 - r2) <= withTolerance && fabs(g1 - g2) <= withTolerance && fabs(b1 - b2) <= withTolerance && fabs(a1 - a2) <= withTolerance; } Everything works so far. But depening on the image, I have a big problem - the time for processing the image. As you can see, the functionality is running within the main thread. I think, it definately makes sense to have a seperate thread for that. But even with threads, it took too much time. Is there any better way to run this function "pretty fast"?'replaceColor' is everytime called, when there is a value change on a UI slider object. For user experience, it is really not good. @objc func toleranceSlider_changed() { let deadlineTime = DispatchTime.now() + .seconds(3) DispatchQueue.main.asyncAfter(deadline: deadlineTime) { //Perform code here self.imageView.image = self.colorUtil.replaceColor(color: (self.COLOR_TO_BE_RELACED), withColor: (self.SELECTED_COLOR), image: (self.imageView.image!), tolerance: CGFloat((self.toleranceSlider.value)), alpha: CGFloat((self.alphaSlider.value))) } }Thanks in advance!
