I'm trying to use API GoogleMaps in an ios app to make an auto-completion, but I can't get my hand on the problem, I search for it but it seems I'm the only one to have it.
MyViewController doesn't conform to protocol GSMAutocompleteViewControllerDelegate
class MyViewController: UIViewController {
#IBAction func onLaunchClicked(sender: AnyObject) {
let acController = GMSAutocompleteViewController()
acController.delegate = self
self.presentViewController(acController, animated: true, completion: nil)
}
}
extension MyViewController: GMSAutocompleteViewControllerDelegate {
func viewController(viewController: GMSAutocompleteViewController!, didAutocompleteWithPlace place: GMSPlace!) {
// The user has selected a place.
self.dismissViewControllerAnimated(true, completion: nil)
}
func viewController(viewController: GMSAutocompleteViewController!, didAutocompleteWithError error: NSError!) {
self.dismissViewControllerAnimated(true, completion: nil)
}
func wasCancelled(viewController: GMSAutocompleteViewController!) {
self.dismissViewControllerAnimated(true, completion: nil)
}
}
It seems like I don't have all the protocol required, but can't get my hand on it.
Thanks for helping :)
Try adding:
func viewController(viewController: GMSAutocompleteViewController!, didFailAutocompleteWithError error: NSError!) {
}

Im trying to build a simple app to scan documents, but faced this error when trying to import VisionKit module, how can i solve this error ?
My code:
import UIKit
import VisionKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func openCameraButtonTaped(_ sender: Any) {
configureDocumentView()
}
private func configureDocumentView() {
let scaningDocumentViewController = VNDocumentCameraViewController()
scaningDocumentViewController.delegate = self
self.present(scaningDocumentViewController, animated: true, completion: nil)
}
}
extension ViewController: VNDocumentCameraViewControllerDelegate {
func documentCameraViewController(_ controller: VNDocumentCameraViewController, didFinishWith scan: VNDocumentCameraScan) {
for pageNum in 0..<scan.pageCount {
let image = scan.imageOfPage(at: pageNum)
print(image)
}
controller.dismiss(animated: true, completion: nil)
}
}
You are giving a hard time for the compiler, your project name conflicts with Apple's VisionKit. Create a new your project with a different name.
Hi want want to make a refer a friend through SMS I write the following code. If user is pick on that open the SMS with text but it don't cancel again user will unable go back to app.
if indexPath.item == 1
{
//SMS
if MFMessageComposeViewController.canSendText() {
let urlToShare = self.referalmodeldata[0].referralCodeOnly
controller1.body = "Hey I just gave an Awesome Assessment on App you can also try it. I scored , Try to beat my score \(String(describing: urlToShare))"
controller1.messageComposeDelegate = self as? MFMessageComposeViewControllerDelegate
self.present(controller1, animated: true, completion: nil)
}
}
You haven't implemented MFMessageComposeViewControllerDelegate correctly in your code.
First of all you need to confirm MFMessageComposeViewControllerDelegate with your UIViewController as shown below:
class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {
Next thing is you need add it's delegate method as shown below:
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
self.dismiss(animated: true, completion: nil)
}
Then you need to replace
controller1.messageComposeDelegate = self as? MFMessageComposeViewControllerDelegate
with
controller1.messageComposeDelegate = self
Demo code will be:
import UIKit
import MessageUI
class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {
#IBAction func sendText(_ sender: Any) {
if (MFMessageComposeViewController.canSendText()) {
let controller = MFMessageComposeViewController()
controller.body = "Message Body"
controller.messageComposeDelegate = self
self.present(controller, animated: true, completion: nil)
}
}
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
self.dismiss(animated: true, completion: nil)
}
}
I have an app that uses a main screen (below) and then a barcode scanner framework to scan in a barcode and then I will code an action to perform. However, the problem I am having is that in the code it takes me back to the scanning screen. I have tried to use present(VC1, animated: true, completion: nil) and it does not know what VC1 is.
I assigned VC1 in Xcode under storyboard id (see below):
Below is my code here for view controller.swift. Now the code takes you back to the scanning screen, but I want to go back to VC1 the main view controller.
import UIKit
import BarcodeScanner
var presentedViewController: UIViewController?
final class ViewController: UIViewController {
#IBOutlet var pushScannerButton: UIButton!
//Present view and handle barcode scanning
#IBAction func handleScannerPush(_ sender: Any, forEvent event: UIEvent) {
let viewController = makeBarcodeScannerViewController()
viewController.title = "Barcode Scanner"
present(viewController, animated: true, completion: nil)
}
private func makeBarcodeScannerViewController() -> BarcodeScannerViewController {
let viewController = BarcodeScannerViewController()
viewController.codeDelegate = self
viewController.errorDelegate = self
viewController.dismissalDelegate = self
return viewController
}
}
// MARK: - BarcodeScannerCodeDelegate
extension ViewController: BarcodeScannerCodeDelegate {
func scanner(_ controller: BarcodeScannerViewController, didCaptureCode code: String, type: String) {
print("Barcode Data: \(code)")
print("Symbology Type: \(type)")
controller.dismiss(animated: true, completion: nil)
// DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
// controller.resetWithError()
// }
}
}
// MARK: - BarcodeScannerErrorDelegate
extension ViewController: BarcodeScannerErrorDelegate {
func scanner(_ controller: BarcodeScannerViewController, didReceiveError error: Error) {
print(error)
}
}
// MARK: - BarcodeScannerDismissalDelegate
extension ViewController: BarcodeScannerDismissalDelegate {
func scannerDidDismiss(_ controller: BarcodeScannerViewController) {
controller.dismiss(animated: true, completion: nil)
}
}
I am trying to do Google Autocomplete using Google Places in Swift 3.0. But I need to search depending upon my current location. Example, If I am in Kolkata, India and I type search keyword "Ko" it will show the results of Kolkata first .
Can anyone help me.
Here is my code.I import GooglePlaces in my class
#IBAction func txtFieldLocationDidStartEditing(_ sender: Any) {
self.placeAutocomplete()
}
func placeAutocomplete() {
let autocompleteController = GMSAutocompleteViewController()
autocompleteController.delegate = self
present(autocompleteController, animated: true, completion: nil)
}
// MARK: - autoComplete Delegates
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
print("Place name: \(place.name)")
dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
print("Error: ", error.localizedDescription)
}
// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
dismiss(animated: true, completion: nil)
}
// Turn the network activity indicator on and off again.
func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = true
}
func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = false
}
Please anyone help me to solve it out.
Thanks in advance.
The only API provided by GMSAutocompleteViewController is to set the GMSCoordinateBounds like so (reference):
func placeAutocomplete() {
let visibleRegion = mapView.projection.visibleRegion()
let bounds = GMSCoordinateBounds(coordinate: visibleRegion.farLeft, coordinate: visibleRegion.nearRight)
let autocompleteController = GMSAutocompleteViewController()
acController.autocompleteBounds = bounds
autocompleteController.delegate = self
present(autocompleteController, animated: true, completion: nil)
}
I want to send a mail from my application. I am doing my first steps with SWIFT and i have stuck at a point. I want to press a button and open up the mail. Can you please tell me how to do the button connection? I think it should be an action but I don't know where to put it on the code
import UIKit
import MessageUI
class ViewController: UIViewController, MFMailComposeViewControllerDelegate {
func sendEmail() {
let mailVC = MFMailComposeViewController()
mailVC.mailComposeDelegate = self
mailVC.setToRecipients([])
mailVC.setSubject("Subject for email")
mailVC.setMessageBody("Email message string", isHTML: false)
presentViewController(mailVC, animated: true, completion: nil)
}
// MARK: - Email Delegate
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
Import library first:
import MessageUI
set delegate like:
MFMailComposeViewControllerDelegate
Write pretty code:
#IBAction func buttonHandlerSendEmail(_ sender: Any) {
let mailComposeViewController = configureMailComposer()
if MFMailComposeViewController.canSendMail(){
self.present(mailComposeViewController, animated: true, completion: nil)
}else{
print("Can't send email")
}
}
func configureMailComposer() -> MFMailComposeViewController{
let mailComposeVC = MFMailComposeViewController()
mailComposeVC.mailComposeDelegate = self
mailComposeVC.setToRecipients([self.textFieldTo.text!])
mailComposeVC.setSubject(self.textFieldSubject.text!)
mailComposeVC.setMessageBody(self.textViewBody.text!, isHTML: false)
return mailComposeVC
}
Also write delegate method like:
//MARK: - MFMail compose method
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
100% working and tested
change sendEmail like this:
#IBAction func sendEmail(sender: AnyObject) {
let mailVC = MFMailComposeViewController()
mailVC.mailComposeDelegate = self
mailVC.setToRecipients([])
mailVC.setSubject("Subject for email")
mailVC.setMessageBody("Email message string", isHTML: false)
presentViewController(mailVC, animated: true, completion: nil)
}
and connect in Interface builder your button to this action
Swift 3
let composer = MFMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
composer.mailComposeDelegate = self
composer.setToRecipients(["Email1", "Email2"])
composer.setSubject("Test Mail")
composer.setMessageBody("Text Body", isHTML: false)
present(composer, animated: true, completion: nil)
}
Delegate method
class SendMailViewController: MFMailComposeViewControllerDelegate {
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
dismiss(animated: true, completion: nil)
}
}
To send mail, generally MFMailComposer is used. It can be tested on device as it doesn't work on iOS simulator.
For testing whether mail service is available or not, use below function,
if !MFMailComposeViewController.canSendMail() {
print("Mail services are not available")
return
}
and to send mail, use below code in your function or action of button.
let composeVC = MFMailComposeViewController()
composeVC.mailComposeDelegate = self
// Configure the fields of the interface.
composeVC.setToRecipients(["email_address#example.com"])
composeVC.setSubject("Hello World!")
composeVC.setMessageBody("Hello from iOS!", isHTML: false)
// Present the view controller modally.
self.presentViewController(composeVC, animated: true, completion: nil)
There is delegate method on completion of sending mail which can be defined as below shown,
func mailComposeController(controller: MFMailComposeViewController,
didFinishWithResult result: MFMailComposeResult, error: NSError?) {
// Check the result or perform other tasks.
// Dismiss the mail compose view controller.
controller.dismissViewControllerAnimated(true, completion: nil)
}
to Anton Platonov add: import MessageUI at the begging of your source file, and when you declaring class for your view controller add protocol: class FirstVC: UIViewController, MFMailComposeViewControllerDelegate{
