The following code was working partially. It display the question step and form. User was able to enter data, but when user click done nothing get save to care store and the display is not updated. Any idea?
class SymptomsVC1: UIViewController{
fileprivate let carePlanStoreManager = CarePlanStoreManager1.sharedCarePlanStoreManager
fileprivate let carePlanData: CarePlanData
fileprivate var symptomTrackerViewController: OCKSymptomTrackerViewController? = nil
required init?(coder aDecoder: NSCoder) {
carePlanData = CarePlanData(carePlanStore: carePlanStoreManager.store)
super.init(coder: aDecoder)
}
override func viewDidLoad() {
super.viewDidLoad()
setViewControllerTitle(self, title: "Symptoms Card")
//creatMenuObject(self)
let symptomTracker = OCKSymptomTrackerViewController.init(carePlanStore: carePlanStoreManager.store)
symptomTracker.progressRingTintColor = UIColor.magenta
symptomTracker.delegate = self
symptomTracker.showEdgeIndicators = true
// Setup the controller's title
symptomTracker.title = NSLocalizedString("Symptoms Card", comment: "")
//change left navigation "Back" button to menu button
var backImage:UIImage = UIImage(named: "menu")!
backImage = backImage.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
let fakeBackButton = UIBarButtonItem(image: backImage, style: UIBarButtonItemStyle.bordered, target: symptomTracker.revealViewController(), action: #selector(SWRevealViewController.revealToggle(_:)))
symptomTracker.navigationItem.leftBarButtonItem = fakeBackButton;
self.navigationController?.pushViewController(symptomTracker, animated: true)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
extension SymptomsVC1: OCKSymptomTrackerViewControllerDelegate {
func symptomTrackerViewController(_ viewController: OCKSymptomTrackerViewController, didSelectRowWithAssessmentEvent assessmentEvent: OCKCarePlanEvent) {
if viewController.progressRingTintColor == UIColor.magenta {
guard let userInfo = assessmentEvent.activity.userInfo,
let task: ORKTask = userInfo["ORKTask"] as? ORKTask else { return }
let taskViewController = ORKTaskViewController(task: task, taskRun: nil)
taskViewController.delegate = self
present(taskViewController, animated: true, completion: nil)
}
}
}
extension SymptomsVC1: ORKTaskViewControllerDelegate {
func taskViewController(_ taskViewController: ORKTaskViewController, didFinishWith
reason: ORKTaskViewControllerFinishReason, error: Error?) {
defer {
dismiss(animated: true, completion: nil)
}
print("task view controller clicked")
guard reason == .completed else { return }
guard let symptomTrackerViewController = symptomTrackerViewController,
let event = symptomTrackerViewController.lastSelectedAssessmentEvent else { return }
let carePlanResult = carePlanStoreManager.buildCarePlanResultFrom(taskResult: taskViewController.result)
print("care plan result")
print(carePlanResult)
carePlanStoreManager.store.update(event, with: carePlanResult, state: .completed) {
success, _, error in
if !success {
print(error?.localizedDescription)
}
}
}
}
I found the fix by adding one line of code in the following function :
override func viewDidLoad() {
super.viewDidLoad()
setViewControllerTitle(self, title: "Symptoms Card")
//creatMenuObject(self)
let symptomTracker = OCKSymptomTrackerViewController.init(carePlanStore: carePlanStoreManager.store)
symptomTracker.progressRingTintColor = UIColor.magenta
symptomTracker.delegate = self
symptomTracker.showEdgeIndicators = true
// Setup the controller's title
symptomTracker.title = NSLocalizedString("Symptoms Card", comment: "")
//*** add the following line, now the result show up in carestore ***
symptomTrackerViewController = symptomTracker
//change left navigation "Back" button to menu button
var backImage:UIImage = UIImage(named: "menu")!
backImage = backImage.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
let fakeBackButton = UIBarButtonItem(image: backImage, style: UIBarButtonItemStyle.bordered, target: symptomTracker.revealViewController(), action: #selector(SWRevealViewController.revealToggle(_:)))
symptomTracker.navigationItem.leftBarButtonItem = fakeBackButton;
self.navigationController?.pushViewController(symptomTracker, animated: true)
}

Please can someone help.I would like to add an alert message once a user clicks on the share button on a pdf viewer, i'm using UIDocumentInteractionController to preview the pdf document. and i wanted to know if there are any delegate methods or functions that i can override, where i can add my alert before opening the sharing sheet?[![enter image description here][1]][1]
class ViewController: UIViewController {
var documentController : UIDocumentInteractionController!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction private func buttonTapped(_ sender: Any) {
guard let fileURL = Bundle.main.url(forResource: "infomation", withExtension: "pdf") else {return}
documentController = UIDocumentInteractionController.init(url: fileURL)
documentController.delegate = self
documentController.presentPreview(animated: true)
}
}
extension ViewController: UIDocumentInteractionControllerDelegate {
func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
return self
}
func documentInteractionControllerWillPresentOpenInMenu(_ controller: UIDocumentInteractionController) {
}
func documentInteractionControllerWillPresentOptionsMenu(_ controller: UIDocumentInteractionController) {
}
func documentInteractionController(_ controller: UIDocumentInteractionController, willBeginSendingToApplication application: String?) {
}
}
but none of them get called when i click on the share button, even though i have set the delegate to be my view controller.is there a way that i can do this ?
Explanation:
There isn't a way to do that without hacking it together by iterating all the sub-views and override the button's action and target.
One clean way is to create your own preview controller like shown below. If you add the QLPreviewController to UINavigationController, it will automatically create a bottom toolbar which you don't want. To work around this, you add it as a child controller of a regular UIViewController and create a custom navigation bar.
You can also use the UTI for the UIActivityItem to determine how the item can be shared. I've only implemented the preview and basic sharing capabilities, but the rest should be super easy to do, and at least it's more customizable than UIDocumentInteractionController since you have full control of everything.
Now for the code that does all of this:

I am currently trying to upload a photo URL and post caption onto my firebase database. The photos are currently being saved on firebase storage which is fine, however I would like for it to also appear on the firebase database.
I repeatedly find myself dealing with this error "Value of type 'StorageMetadata' has no member 'downloadURL'"
I understand that in firebase 5 to get the url from storage you need to call downloadURL on storage reference, not metadata. I have tried multiple ways and examples, but it all leads to errors.screenshot of error

Use Above code, it will successfully upload the image and post that to the Firebase Database
Currently I bought a source code for a social media app that uses firebase for the sign up/ log in page, but I'm seeing that log in page has no background image and sign up buttons are at the bottom leaving a blank screen on the entire page.
I'm a noobi when it comes to coding in xCode so hope you can help me with adding a background image.
So currently I have 2 files that control the Auth screen (Authclient.swift & WelcomeViewController.swift)
I've been going through the files and looks like "WelcomeViewController.swift" controls the sign in screen... This is the code I have in that file:

Can anyone point me in the right direction to add a background image to this screen. Already have my 3 images in Assets.xcassets named bgLogin.imageset.
Thanks
This is what you want to do.
Create an extension of their baseViewController
extension FUIAuthBaseViewController {
Inside of that extension, override their viewWillAppear() and set the image there
open override func viewWillAppear(_ animated: Bool) {
self.navigationItem.leftBarButtonItem = nil
self.view.backgroundColor = .white
// if view is base view add logo as subview
let vc = self.navigationController?.viewControllers.first
if vc == self.navigationController?.visibleViewController {
makeLogoImage()
} else {
// hide the image in proceeding views by covering it with a white background
vc?.view.backgroundColor = .white
}
}
/**
Create imageView and display it at the top of the screen.
*/
func makeLogoImage() {
let imageView = UIImageView(image: UIImage(named: "angel.png"))
let width = view.frame.width
let height = view.frame.height
imageView.frame = CGRect(x: width / 4, y: height / 8 , width: width / 2, height: width / 2)
imageView.contentMode = .scaleAspectFill
self.view.addSubview(imageView)
self.view.sendSubview(toBack: imageView)
}
I'm using the Spotify iOS SDK. When a user logs into Spotify using the app, on call back loginVC transitions to musicPlayerVC.

I am looking at adding an inital note to the note page within my app. this is so that when people click to the notes part there will be some detail on how to use it rather than just a big empty screen. I have no idea where to implement this though. Could you please help, below is the page where it talks about the dictionaries.

if let myWebsite = NSURL(string: "")
{
let objectsToShare = [textToShare, myWebsite]
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
self.presentViewController(activityVC, animated: true, completion: nil)
}
OpenMail()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
tView.text = (allNotes[currentNoteIndex] as Note).note
tView.becomeFirstResponder()
// Set controller as swipe gesture recogniser, to allow keyboard dismissal for text box
var swipe: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "dismissKeyboard")
swipe.direction = UISwipeGestureRecognizerDirection.Down
self.view.addGestureRecognizer(swipe)
self.tView.delegate = self

Add an NSUserDefault boolean that stores whether or not the initial note should be shown, e.g. that the app has been launched for the first time. Then load an initial note accordingly. When a note is added or the initial note is deleted, then change the boolean accordingly so the initial note doesn't show up next time.
You could also initialize your database with an initial note. Not clear from your code how the notes are saved, but this approach would probably rely on the NSUserDefault approach above, except it could be done in the AppDelegate or something.
example:
let InitialSetupComplete = "InitialSetupComplete" // Note: I would define this at the top of a file
let defaults = NSUserDefaults.standardUserDefaults()
if defaults.boolForKey(InitialSetupComplete) {
// Show initial note
}
// Later on when the note is deleted, or modified (or immediately after initial note loaded into the database, see below)
defaults.setBool(true, forKey: InitialSetupComplete)
Would be easier/cleaner just to initialize your database with the initial note in the app delegate (e.g. call within applicationDidFinishLaunching), so your view controller doesn't have to figure this out. Similar code, except you would use setBool right away after the initial note has been saved to the database. I don't know anything about your database from the question, so can't really provide a more detailed example than this. Hope this helps.
