Closed 5 years ago.
I am attempting to create a application in xcode 8 swift 3 where the user adds an image using a imagePickerController then when the user clicks either save or exits the imagePickerController I want the image to be saved locally, so next time the app is loaded (for example after a device restart) the image is there. Just to be clear I Do Not want to save the image to the camera roll. Here is my code thus far without any save or load methods, (just the save button reference) any help would be very appreciated as I have been attempting to do this for a long while.
import UIKit
class timetable: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
#IBOutlet var imageviewtimetable: UIImageView!
#IBAction func save(_ sender: Any) {
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func selectImageFromPhotoLibrary(_ sender: Any) {
let imagePickerController = UIImagePickerController()
imagePickerController.sourceType = .photoLibrary
imagePickerController.delegate = self
present(imagePickerController, animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController){
dismiss(animated: true, completion:nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
imageviewtimetable.image = selectedImage
dismiss(animated: true,completion:nil)
}
}

Save image in Document Directory
func saveImageDocumentDirectory() {
let fileManager = NSFileManager.defaultManager()
let paths = (getDirectoryPath() as NSString).stringByAppendingPathComponent("apple.jpg")
let image = UIImage(named: "apple.jpg")
print(paths)
let imageData = UIImageJPEGRepresentation(image!, 0.5)
fileManager.createFileAtPath(paths as String, contents: imageData, attributes: nil)
}
Get Document Directory Path
func getDirectoryPath() -> String {
let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let documentsDirectory = paths[0]
return documentsDirectory
}
get Image from document directory
func getImage(){
let fileManager = NSFileManager.defaultManager()
let imagePath = (self.getDirectoryPath() as NSString).stringByAppendingPathComponent("apple.jpg")
if fileManager.fileExistsAtPath(imagePath){
self.imageView.image = UIImage(contentsOfFile: imagePath)
} else {
print("No Image")
}
}
create Directory
func createDirectory(){
let fileManager = NSFileManager.defaultManager()
let paths = getDirectoryPath() as NSString).stringByAppendingPathComponent("customDirectory")
if !fileManager.fileExistsAtPath(paths){
try! fileManager.createDirectoryAtPath(paths, withIntermediateDirectories: true, attributes: nil)
} else {
print("Already dictionary created.")
}
}
