I’m unable to select the document documents they are greyed out
I have tried with
UIDocumentPickerViewController - each file that was picked once is then grayed out
import UIKit
import MobileCoreServices
import UniformTypeIdentifiers
class ViewController: UIViewController, UINavigationControllerDelegate, UIDocumentPickerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func ShowPicker(_ sender: Any) {
let pickerViewController = UIDocumentPickerViewController(forOpeningContentTypes: [.pdf], asCopy: true)
pickerViewController.delegate = self
pickerViewController.allowsMultipleSelection = false
pickerViewController.shouldShowFileExtensions = true
present(pickerViewController, animated: true, completion: nil)
}
func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
print("Cancelled")
}
func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
print("didPickDocuments at \(urls)")
}
}

How can I write the following code with UIViewControllerRepresentable?
I want to use UIViewControllerRepresentable. I want the code I write to be regular. Do you think it makes sense to write this code with UIViewControllerRepresentable?
import MessageUI
class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {
#IBOutlet weak var phoneNumber: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func sendText(sender: UIButton) {
if (MFMessageComposeViewController.canSendText()) {
let controller = MFMessageComposeViewController()
controller.body = "Message Body"
controller.recipients = [phoneNumber.text]
controller.messageComposeDelegate = self
self.presentViewController(controller, animated: true, completion: nil)
}
}
func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
//... handle sms screen actions
self.dismissViewControllerAnimated(true, completion: nil)
}
override func viewWillDisappear(animated: Bool) {
self.navigationController?.navigationBarHidden = false
}
}
SMSViewController
struct SMSViewController: UIViewControllerRepresentable {
class Coordinator: NSObject, MFMessageComposeViewControllerDelegate {
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
}
var parent: MFMessageComposeViewController
init(_ parent: MFMessageComposeViewController) {
self.parent = parent
}
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
func makeUIViewController(context: UIViewControllerRepresentableContext<MFMessageComposeViewController>) -> MFMessageComposeViewController {
let messageViewController = MFMessageComposeViewController()
messageViewController.delegate = context.coordinator
return messageViewController
}
func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {
}
}
I am trying to implement auto search for address in my App using SwiftUI. Google tutorial are based on UIKit, I was hoping if someone has tried and can guide me to the right direction. Thanks
Try this code; it works for me.
import Foundation
import UIKit
import SwiftUI
import GooglePlaces
struct PlacePicker: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
#Environment(\.presentationMode) var presentationMode
#Binding var address: String
func makeUIViewController(context: UIViewControllerRepresentableContext<PlacePicker>) -> GMSAutocompleteViewController {
let autocompleteController = GMSAutocompleteViewController()
autocompleteController.delegate = context.coordinator
let fields: GMSPlaceField = GMSPlaceField(rawValue: UInt(GMSPlaceField.name.rawValue) |
UInt(GMSPlaceField.placeID.rawValue))!
autocompleteController.placeFields = fields
let filter = GMSAutocompleteFilter()
filter.type = .address
filter.country = "ZA"
autocompleteController.autocompleteFilter = filter
return autocompleteController
}
func updateUIViewController(_ uiViewController: GMSAutocompleteViewController, context: UIViewControllerRepresentableContext<PlacePicker>) {
}
class Coordinator: NSObject, UINavigationControllerDelegate, GMSAutocompleteViewControllerDelegate {
var parent: PlacePicker
init(_ parent: PlacePicker) {
self.parent = parent
}
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
DispatchQueue.main.async {
print(place.description.description as Any)
self.parent.address = place.name!
self.parent.presentationMode.wrappedValue.dismiss()
}
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
print("Error: ", error.localizedDescription)
}
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
parent.presentationMode.wrappedValue.dismiss()
}
}
}
I wanted to programmatically control the menu view so I tried the following:
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var menuView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func menuBtn(_ sender: UIButton) {
print("menuBtn")
print(type(of: menuView!)) // <- `Thread 1:EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)`
}
}
And click the button, console says
fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)
Both are connected to ViewController.
How can I get print(type(of: menuView!))?
===============================================================
ps.
I've simplified my real problem. this is my real code:
button on ViewController.Swift
#IBAction func openModal(_ sender: UIButton) {
print("open btn clicked")
let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "menuViewController") as! MenuViewController
self.addChildViewController(vc)
self.view.addSubview(vc.contentView!) /// <- This cause problem
}
MenuViewController.swift
import UIKit
class MenuViewController: UIViewController {
#IBOutlet weak var contentView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = UIColor.clear
view.isOpaque = false
}
#IBAction func closeBtn(_ sender: UIButton) {
print("close btn clicked")
self.view.removeFromSuperview()
}
}
and Why I wan't using it:
I can't scrolling when menuView appeared.. I want to use the buttons in the menu view and scroll at the same time.
How to Search Google Places when i click on textFieldand want to show results just below textField. I am using Swift 3.0 version.Could someone help me
First you need to install the GooglePlaces SDK in your project. Then you refer the code bellow.
in Swift 3
In AppDelegate
import UIKit
import CoreData
import GoogleMaps
import GooglePlacePicker
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions
launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
func setUpGoogleMaps()
return true
}
func setUpGoogleMaps() {
let googleMapsApiKey = "AIzaSyA-kiOBvrR9CNztqutwmKaSLyXIid93K0E"
GMSServices.provideAPIKey(googleMapsApiKey)
GMSPlacesClient.provideAPIKey("AIzaSyA-kiOBvrR9CNztqutwmKaSLyXIid93K0E")
}
In your ViewController which is having the textField
import UIKit
import GooglePlaces
import GoogleMaps
import GooglePlacePicker
class HotelVC: UIViewController, GMSMapViewDelegate, UITextFieldDelegate {
#IBOutlet weak var YourTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
self.YourTextField.delegate = self
}
func textFieldDidBeginEditing(_ textField: UITextField) {
let acController = GMSAutocompleteViewController()
acController.delegate = self
self.present(acController, animated: true, completion: nil)
}
}
extension viewController: GMSAutocompleteViewControllerDelegate {
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
print("Place name: \(place.name)")
print("Place address: \(place.formattedAddress ?? "null")")
self.YourTextField.text = place.formattedAddress
print("Place attributions: \(String(describing: place.attributions))")
self.dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
// print("Error: \(error.description)")
self.dismiss(animated: true, completion: nil)
}
// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
print("Autocomplete was cancelled.")
self.dismiss(animated: true, completion: nil)
}
}
You will get location from the selected place. Try this code.
public func viewController(viewController: GMSAutocompleteViewController, didAutocompleteWithPlace place: GMSPlace) {
var lat = place.coordinate.latitude
var lon = place.coordinate.longitude
print("lat lon",lat,lon)
}
I am just starting to use swift3 in Xcode in order to utilize ResearchKit provided by Apple.inc.
Although I have worked through tutorials from Researchkit Tutorial with Swift: Getting started in Ray Wenderlich, I have a trouble in the extension of ViewController. The following is my code.
import ResearchKit
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func consentTapped(sender : AnyObject) {
let taskViewController = ORKTaskViewController(task: ConsentTask, taskRun: nil)
taskViewController.delegate = self
present(taskViewController, animated: true, completion: nil)
}
}
extension ViewController: ORKTaskViewControllerDelegate {
func taskViewController(taskViewController: ORKTaskViewController, didFinishWithReason
reason: ORKTaskViewControllerFinishReason, error: NSError?) {
//Handle results with taskViewController.result
taskViewController.dismiss(animated:true, completion: nil)
}
}
You've missed to add delegate. Add ORKTaskViewControllerDelegate to ViewController
class ViewController: UIViewController,ORKTaskViewControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad(
}
}
