Using multiple tap gesture recognizers with imagePickerController

Hi,

I'm trying to upload two different images on a single view to a cloud storage. For this i have created two imagesViews and two tap gesture recognizers. I'm stuck in identifying the clicked tap gesture recognizer. Anyone able to help me out? I've posted the code below. The upload is working but both functions are calling the same imagePickerController but i need to have parts of the code in the imagePickerController different.

Thanks, Patrick

@IBAction func handleProfileImageUpload(sender: AnyObject) {
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.allowsEditing = true
        presentViewController(picker, animated: true, completion: nil)
}

@IBAction func handleProfileTitleImageUpload(sender: AnyObject) {
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.allowsEditing = true
        presentViewController(picker, animated: true, completion: nil)
}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
        dismissViewControllerAnimated(true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        var selectedImageFromPicker: UIImage?

        if let editedImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
            selectedImageFromPicker = editedImage
        } else if let originalImage = info["UIImagePickerControllerOriginalImage"] as? UIImage     {
            selectedImageFromPicker = originalImage
        }
.........

I hope I understand your problem correctly and not simplifying it too much: you can use a class variable and set it to a different value in each IBAction function (handleProfileTitleImageUpload or handleProfileImageUpload) before you show the picker dialog.. then inside the picker didFinishPickingMediaWithInfo function you can check which value does the variable have and decide what to do with the image. ''' var callingGesture: Int = 0

@IBAction func handleProfileImageUpload(sender: AnyObject) {

    let picker = UIImagePickerController()
  picker.delegate = self
    picker.delegate = self
    picker.allowsEditing = true
    callingGesture = 1
    presentViewController(picker, animated: true, completion: nil)
}

@IBAction func handleProfileTitleImageUpload(sender: AnyObject) {

    let picker = UIImagePickerController()
    picker.delegate = self
    picker.allowsEditing = true
    callingGesture = 2
    presentViewController(picker, animated: true, completion: nil)
}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    dismissViewControllerAnimated(true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

    var selectedImageFromPicker: UIImage?

    if let editedImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
        selectedImageFromPicker = editedImage
    } else if let originalImage = info["UIImagePickerControllerOriginalImage"] as? UIImage     {
        selectedImageFromPicker = originalImage
    }
picker.dismissViewControllerAnimated(true, completion: nil)
    if callingGesture == 1 {
        // do this 
    } else if callingGesture == 2 {
        //do that
    }
}
