how to select three different images for three images using imagepicker.. please do guide me

Answer 1

The reason is there is no thing here that can differentiate which button is clicked , hence result set to all imageviews
func didSelect(image: UIImage?, video: URL?, fileName: String?) {
if let img = image{
profilePicImage.image = img
}
if let img1 = image{
leftProfilePicImg.image = img1
}
if let img2 = image{
rightProfilePicImg.image = img2
}
}
You need
enum ImageChooser {
case profile,left,right
}
class EditProfileImagesVC: UIViewController {
private var imagePicker : EasyImagePicker?
#IBOutlet weak var profilePicImage: UIImageView!
#IBOutlet weak var leftProfilePicImg: UIImageView!
#IBOutlet weak var rightProfilePicImg: UIImageView!
var chooser:ImageChooser = .profile
override func viewDidLoad() {
super.viewDidLoad()
imagePicker = EasyImagePicker(presentationController: self, delegate: self)
}
#IBAction func profilePicBtn(_ sender: UIButton) {
chooser = .profile
imagePicker?.present(from: sender, mediaType: .images, onViewController: self)
}
#IBAction func leftProfileBtn(_ sender: UIButton) {
chooser = .left
imagePicker1?.present(from: sender, mediaType: .images, onViewController: self)
}
#IBAction func rightProfileBtn(_ sender: UIButton) {
chooser = .right
imagePicker2?.present(from: sender, mediaType: .images, onViewController: self)
}
}
extension EditProfileImagesVC : EasyImagePickerDelegate{
func didSelect(image: UIImage?, video: URL?, fileName: String?) {
if let img = image {
if chooser == .profile {
profilePicImage.image = img
}
else
if chooser == .left {
leftProfilePicImg.image = img
}
else
if chooser == .right {
rightProfilePicImg.image = img
}
}
}
}

Add picker reference to func didSelect(image: UIImage?, video: URL?, fileName: String?)
This way func didSelect(picker: EaseImagePicker, image: UIImage?, video: URL?, fileName: String?)
From picker call it with the reference to self
didSelect(picker: self, image: selectedImage, video: nil, fileName: nil)
func didSelect(picker: EaseImagePicker, image: UIImage?, video: URL?, fileName: String?) {
if let img = image{
switch picker {
case imagePicker:
profilePicImage.image = img
case imagePicker1:
leftProfilePicImg.image = img
case imagePicker2:
rightProfilePicImg.image = img
default:
break
}
}
}
