I'm looking for a little help on how to populate text into a twitter post, using the button below I can get a label to show "00:35' Goal for"
When the button is clicked I would like to open twitter which I can work out, and populate it ready for tweeting.
#IBAction func goalClicked(_ sender: UIButton) {
tempTimelineLbl.text = "\(stopWatchString)' \("Goal for")"
}
I will use the code below to open twitter
let twUrl: URL = URL(string: "twitter://user?screen_name=\(club.twitter)")!
let twUrlWeb: URL = URL(string: "https://twitter.com/\(club.twitter)")!
if (UIApplication.shared.canOpenURL(twUrl)) {
UIApplication.shared.open(twUrl, options: [:], completionHandler: {
(Sucess) in
})
} else {
UIApplication.shared.open(twUrlWeb, options: [:], completionHandler: {
(Sucess) in
})
}
Followed this
https://developer.apple.com/reference/social/slcomposeviewcontroller
#IBAction func goalClicked(_ sender: UIButton) {
let stopWatchString = stopWatch.elapsedTimeSinceStart()
stopwatchLabel.text = stopWatchString
let vc = SLComposeViewController(forServiceType: SLServiceTypeTwitter)
vc?.setInitialText("Some Test String")
vc?.add(#imageLiteral(resourceName: "goal"))
present(vc!, animated: true, completion: nil)
}

The below code used to work in Xcode8. But now it is not working in Xcode 9.1 with target iOS11.
I did the following:
class ViewController: UIViewController {
var documentInteractionController: UIDocumentInteractionController = UIDocumentInteractionController()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func ShareImages(_ sender: AnyObject)
{
let urlWhats = "whatsapp://app"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed) {
if let whatsappURL = URL(string: urlString) {
if UIApplication.shared.canOpenURL(whatsappURL as URL) {
if let image = UIImage(named: "whatsappIcon") {
if let imageData = UIImageJPEGRepresentation(image, 1.0) {
let tempFile = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/whatsAppTmp.wai")
do {
try imageData.write(to: tempFile, options: .atomic)
self.documentInteractionController = UIDocumentInteractionController(url: tempFile)
self.documentInteractionController.uti = "net.whatsapp.image"
self.documentInteractionController.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)
} catch {
print(error)
}
}
}
} else {
// Cannot open whatsapp
}
}
}
}
// Added this in info.plist
<key>LSApplicationQueriesSchemes</key>
<array>
<string>whatsapp</string>
</array>
I have a little code which allows me to play a local file when I hit a UIButton. But what I want is to play multiple files on 3 different UIButtons because I have 3 video files which I want to attach to my app.
This is the current code:
import UIKit
import AVFoundation
import AVKit
class ViewController: UIViewController {
var playerController = AVPlayerViewController()
var player:AVPlayer?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let videoString:String? = Bundle.main.path(forResource: "Video", ofType: ".mp4")
if let url = videoString {
let videoURL = NSURL(fileURLWithPath: url)
self.player = AVPlayer(url: videoURL as URL)
self.playerController.player = self.player
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func PlayVideo(_ sender: AnyObject) {
self.present(self.playerController, animated: true, completion: {
self.playerController.player?.play()
})
}
}
You can create url for different video file in your button click funtions
#IBAction func Button1Click(_ sender: AnyObject) {
let videoString:String? = Bundle.main.path(forResource: "Video1", ofType: ".mp4")
if let url = videoString {
let videoURL = NSURL(fileURLWithPath: url)
self.player = AVPlayer(url: videoURL as URL)
self.playerController.player = self.player
}
self.present(self.playerController, animated: true, completion: {
self.playerController.player?.play()
})
}
#IBAction func Button2Click(_ sender: AnyObject) {
let videoString:String? = Bundle.main.path(forResource: "Video2", ofType: ".mp4")
if let url = videoString {
let videoURL = NSURL(fileURLWithPath: url)
self.player = AVPlayer(url: videoURL as URL)
self.playerController.player = self.player
}
self.present(self.playerController, animated: true, completion: {
self.playerController.player?.play()
})
}
#IBAction func Button3Click(_ sender: AnyObject) {
let videoString:String? = Bundle.main.path(forResource: "Video3", ofType: ".mp4")
if let url = videoString {
let videoURL = NSURL(fileURLWithPath: url)
self.player = AVPlayer(url: videoURL as URL)
self.playerController.player = self.player
}
self.present(self.playerController, animated: true, completion: {
self.playerController.player?.play()
})
}
Hello everybody I'm trying to build a simple one view program to call and navigate a voice menu, I cannot get the UserDefaults to properly save between closing of the app. I've also had issue with getting text to display in the UITextField, I would like for it to display if saved on launch, here is a description of vars:
UserInput - text field for employee ID (what needs saving)
Switch - if Save it is 1 save data, if 0 do not
Submit - submit button that should save the data and call.
This is my first iPhone app and any help would be much appreciated!
enter code here
import UIKit
class ViewController: UIViewController, UITextFieldDelegate {
#IBOutlet weak var UserInput: UITextField!
var SaveIt = true
var employID = ""
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.UserInput.delegate = self;
UserInput.keyboardType = .numberPad
if let current_eid = UserDefaults.standard.string(forKey: "emp_ID") {
UserInput.text = current_eid
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func loadDefaults() {
let defaults = UserDefaults.standard
if let UserInput = defaults.string(forKey: "emp_ID") {
print(UserInput)
} else {
// focus on the text field if it's empty
UserInput.becomeFirstResponder() }
UserInput.text = defaults.object(forKey: "emp_ID") as! String?
}
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
#IBAction func Switch(_ sender: UISwitch) {
if (sender.isOn == true) {
SaveIt = true
}
else{
SaveIt = false
}
}
#IBAction func Submit(_ sender: Any) {
if (SaveIt) {
let defaults = UserDefaults.standard
defaults.set(UserInput.text, forKey: "emp_ID")
defaults.synchronize()
}
let phone = "telprompt://1888247889pppp" + UserInput.text! + "p1p1p1p1";
let url = URL(string:phone)!
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else { UIApplication.shared.openURL(url)
}
}
}
I want the user to be taken to a new viewController after clicking "use photo" after taking a picture. However, the segue is never performed. I have attempted this segue by connecting two viewControllers via a manual segue. I have a print statement in my imagePickerController function which is where my segue code is. This print statement prints when I click "use photo", so why is my segue be ignored? I tried this exact same segue code within a "#IBAction func someButton (_sender: UIButton)" and it worked fine? Any help would be appreciated.
Here is my code:
import UIKit
class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
#IBOutlet weak var imageTake: UIImageView!
var imagePicker: UIImagePickerController!
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 takePhoto(_ sender: UIButton) {
imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .camera
present(imagePicker, animated: true, completion: nil)
}
#IBAction func photoLib(_ sender: UIButton) {
imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .photoLibrary
present(imagePicker, animated: true, completion: nil)
}
#IBAction func save(_ sender: AnyObject) {
UIImageWriteToSavedPhotosAlbum(imageTake.image!, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
}
func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
if let error = error {
// we got back an error!
let ac = UIAlertController(title: "Save error", message: error.localizedDescription, preferredStyle: .alert)
ac.addAction(UIAlertAction(title: "OK", style: .default))
present(ac, animated: true)
} else {
let ac = UIAlertController(title: "Saved!", message: "Your altered image has been saved to your photos.", preferredStyle: .alert)
ac.addAction(UIAlertAction(title: "OK", style: .default))
present(ac, animated: true)
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
imagePicker.dismiss(animated: true, completion: nil)
imageTake.image = info[UIImagePickerControllerOriginalImage] as? UIImage
print("made it")
performSegue(withIdentifier: "new", sender: self)
}
}
Here's a suggestion. You have this:
imagePicker.dismiss(animated: true, completion: nil)
// ...
performSegue(withIdentifier: "new", sender: self)
Change it to this:
imagePicker.dismiss(animated: true, completion: {
performSegue(withIdentifier: "new", sender: self)
})
That way, we don't try to perform the segue until the image picker is in fact completely dismissed.
If that doesn't work, then I would have to conclude that there is no such segue as "new" coming from this view controller. But you have not shown your storyboard so I can't be certain.
I get an error when selecting an image with UIImagePicker:
[Generic] Creating an image format with an unknown type is an error
I'm using Xcode 8.1 and Swift 3.
I've already searched all around the web but nothing seems to solve my problem, please help!
Here it's my code:
class TabBarController: UITabBarController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
var isSelected: Bool = false
var imgPicker: UIImagePickerController = UIImagePickerController()

imgPicker.allowsEditing = false
imgPicker.sourceType = .photoLibrary
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
imgPicker.dismiss(animated: true, completion: nil)
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
self.performSegue(withIdentifier: "toPostPicture", sender: image)
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
func askImagePickerSource(sender: UIViewController) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

})
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (UIAlertAction) in
sender.dismiss(animated: true, completion: nil)
}
alert.addAction(cameraAction)
alert.addAction(photoLibraryAction)
alert.addAction(cancelAction)
sender.present(alert, animated: true, completion: nil)
} else {
self.imgPicker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
sender.present(self.imgPicker, animated: true, completion: nil)
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "toPostPicture" {
if let postPictureVC = segue.destination as? PostPictureVC {
if let image = sender as? UIImage {
postPictureVC.image = image
}
}
}
}
}
I faced the same issue by not adding delegate as 'self' for the UIImagePickerController. After adding it I was able to get the selected image from gallery. But even after adding delegate as self and able to access the image (Display on an ImageView), I was still getting the same error. After a further research on SO I got to know that this is just a bug and doesn't affect the app in any way.

Can you post the .debugDescription of the info parameter in your picker delegate?
func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [String : Any]) {
print(info.debugDescription)
...
}
