User want to interact on click of push notification and send comment/reply/message.
I have following code in AppDelegate:
func configureNotification() {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
center.delegate = notificationDelegate
let replyAction = UNTextInputNotificationAction(identifier: replyID, title: "Add reply", options: [], textInputButtonTitle: "Send", textInputPlaceholder: "Reply here")
let deafultCategory = UNNotificationCategory(identifier: "CustomSamplePush", actions: [replyAction], intentIdentifiers: [], options: [])
center.setNotificationCategories(Set([deafultCategory]))
UIApplication.shared.registerForRemoteNotifications()
}
And Handle action like following:
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: #escaping () -> Void) {
let identifier = response.actionIdentifier
let request = response.notification.request
if identifier == replyID{
let textResponse = response as! UNTextInputNotificationResponse
let newContent = request.content.mutableCopy() as! UNMutableNotificationContent
newContent.body = textResponse.userText
addNotification(content: newContent, trigger: request.trigger, indentifier: request.identifier)
}
completionHandler()
}
func addNotification(content:UNNotificationContent,trigger:UNNotificationTrigger?, indentifier:String){
let request = UNNotificationRequest(identifier: indentifier, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: {
(errorObject) in
if let error = errorObject{
print("Error \(error.localizedDescription) in notification \(indentifier)")
}
})
}
FYI : This code perfectly run for iOS 11 device but not working in iOS 13

I am trying to create an extension on Button that reduces the boilerplate when creating them with a system image.
extension Button {
init(_ systemName: String, action: #escaping () -> Void) {
self.init {
action()
} label: {
Image(systemName: systemName) // <-- Error
}
}
}
This results in the following compiler error:
Cannot convert value of type 'Image' to closure result type 'Label'
Looking at Button's initializer, I see it declared like this:
struct Button<Label> : View where Label : View {
init(action: #escaping () -> Void, #ViewBuilder label: () -> Label) { ... }
}
But specifying my extension similarly also doesn't work. Where am I going wrong?
extension Button where Label : View {
There are two immediate issues with your approach:
You need to specify that your Label is of type Image
The signature you're using will collide with an existing constructor for Button (Button(_ title: StringProtocol, action: () -> Void))
You could address both with your extension:
extension Button where Label == Image {
init(systemName: String, action: #escaping () -> Void) {
self.init(action: action, label: { Image(systemName: systemName) })
}
}
But it feels more in line with SwiftUI's API to make your own Button wrapper:
struct SystemImageButton: View {
let action: () -> Void
let systemName: String
init(systemName: String,
action: #escaping () -> Void) {
self.action = action
self.systemName = systemName
}
var body: some View {
Button(action: action,
label: { Image(systemName: systemName) })
}
}
You need to specify generics type, like
extension Button where Label == Image { // << here !!
init(_ systemName: String, action: #escaping () -> Void) {
self.init {
action()
} label: {
Image(systemName: systemName) // << No Error !!
}
}
}
Tested with Xcode 12.5 / iOS 14.5
Note: see for details how system extensions for Text label declared
extension Button where Label == Text {
#available(iOS 13.0, macOS 10.15, tvOS 13.0, watchOS 6.0, *)
extension Button where Label == Text {
public init(_ titleKey: LocalizedStringKey, action: #escaping () -> Void)
Had this working on the last few versions of iOS but on 14 cannot get this to work, I have spent the past 5 days Googling.
Whenever I go to add an image from the gallery the popup to select an image is blank.
I have tried UIImagePickerController(which works fine iOS13 and below) and the new PHPickerViewController.
What has been working up until iOS14 is the user clicks a bar button to "add image" and the pop up asks to pick from the gallery and then presents the picker with images in your gallery.
I have set the Info.plist "Privacy - Photo Library Usage Description" for UIImagePickerController, I know the PHPickerViewController doesn't need perms as it handles getting the image for you.
I have also been seeing these purple warning now and again saying "xxxx must be used from main thread only", never seen that before until the new Xcode.
Any help would be much appreciated. Running Xcode 12.0.1 (12A7300), simulators running iOS14.

On iOS 14 the restricted image picker permission dialog opens in a separate thread, so when the authorization return you will need to perform UI tasks on main thread.
PHPhotoLibrary.requestAuthorization({
(newStatus) in
DispatchQueue.main.async {
print("status is \(newStatus)")
if newStatus == PHAuthorizationStatus.authorized {
self.showGallery()
print("success")
}
}
})
If this is helpful for anyone else I discovered that editing the scrollview appearance proxy background caused a bug in both the UIImagePickerController and the PHPickerViewController preventing them from showing images in iOS 14 and above. I had edited the scrollview background proxy because it is black even in light mode. After hours of googling and testing I discovered that removing the appearance background modification on the scrollview proxy allowed the image pickers to function as expected. I filed a bug report with Apple. The line of code that caused the bug was:
UIScrollView.appearance().backgroundColor = .systemBackground

}
You are getting that error because your url is nil.
It is nil because you are creating the user, upon successful creation self.uploadProfileImage(image) is called in order to get the image url of the current user but the user is not logged in.
A solution would be:
Sign in the user and upon success then call uploadProfileImage.
I got some error when I send photo message.

You just need to understand what is going on in your code , as i am looking into your code you are reloading collectionview before the JSQPhotoMediaItem or JSQVideoMediaItem objects are completely configured and added these MediaItem into your message array, so make sure you have completely configured your JSQPhotoMediaItem and JSQVideoMediaItem objects and only after that you add these object to your message array.
you can add this into your switch case condition
case "PHOTO":
let photo = JSQPhotoMediaItem(image: nil)
let fileUrl = dict["fileUrl"] as! String
let downloader = SDWebImageDownloader.shared()
downloader.downloadImage(with: URL(string: fileUrl)!, options: [], progress: nil, completed: { (image, data, error, finished) in
DispatchQueue.main.async(execute: {
photo?.image = image // you have image in your media object
if self.senderId == senderId {
photo?.appliesMediaViewMaskAsOutgoing = true
} else {
photo?.appliesMediaViewMaskAsOutgoing = false
}
// you just configured media object by using appliesMediaViewMaskAsOutgoing
self.messages.append(JSQMessage(senderId: senderId, displayName: senderName, media: photo))
// successfully added object into your message array now you should reload collectionview
self.collectionView.reloadData()
})
})
//same goes for your video condition
But still i would recommend you to follow each step one by one.
Follow these steps for adding A JSQPhotoMediaItem object
make a JSQPhotoMediaItem Object like
let photoItem = JSQPhotoMediaItem(image: UIImage(named: <your Image Object>))
make sure you have downloaded your image from server and successfully have your image object ready to add in the JSQPhotoMediaItem Object (as you are downloading it from firebase) first get the image then add it to your JSQPhotoMediaItem
now you have to tell your message type( outgoing or incoming ) so add appliesMediaViewMaskAsOutgoing property to according to you need so this would be in your code
if self.senderId == senderId {
photoItem?.appliesMediaViewMaskAsOutgoing = true
} else {
photoItem?.appliesMediaViewMaskAsOutgoing = false
}
now this is the final step for appending this object to your array
self.messages.append(JSQMessage(senderId: senderId, displayName: senderName, media: photoItem))
now reload collectionView as you have successfully configured your media item ( JSQPhotoMediaItem )
self.collectionView.reloadData()
same goes for the JSQVideoMediaItem objects.
I'm getting crazy with this.
While migrating a simple UIIMagePicker implementation I have everything working properly , no issues, no warning.
Running on both simulator and device the PickerController just don't take into consideration the new image and won't apply to the UImageView.
This is my code:
#IBOutlet weak var profilePictureImageView: UIImageView!
let picker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
picker.delegate = self
}
//Opening Camera to take a new picture
#IBAction func takeNewPictureButtonDidTouch(_ sender: AnyObject) {
if UIImagePickerController.isSourceTypeAvailable(.camera) {
picker.allowsEditing = false
picker.sourceType = UIImagePickerControllerSourceType.camera
picker.cameraCaptureMode = .photo
picker.modalPresentationStyle = .fullScreen
present(picker,animated: true,completion: nil)
} else {
noCamera()
}
}
//Opening the library to select an existing picture
#IBAction func openPicturesLibraryButtonDidTouch(_ sender: AnyObject) {
picker.allowsEditing = false
picker.sourceType = .photoLibrary
picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
picker.modalPresentationStyle = .popover
present(picker, animated: true, completion: nil)
}
//MARK: - Delegates
func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [String : AnyObject])
{
var chosenImage = UIImage()
chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage //2
profilePictureImageView.contentMode = .scaleAspectFill //3
profilePictureImageView.image = chosenImage //4
dismiss(animated:true, completion: nil) //5
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func noCamera(){
let alertVC = UIAlertController(
title: "No Camera",
message: "Sorry, this device has no camera",
preferredStyle: .alert)
let okAction = UIAlertAction(
title: "OK",
style:.default,
handler: nil)
alertVC.addAction(okAction)
present(
alertVC,
animated: true,
completion: nil)
}
}
set delegate to self in viewdidload
