Saving and Loading Images, Swift 2.0

Were you looking for the best games to play at daisyslots? Why not try starburst or fluffy favorite to experience something new? This will show you how to save and load images in a way that is very easy and straight forward. Here is the function to save your image first. We’ll assume you already […]

Pick an Image / image picker

This example is to show how to pick an image from a soure ( in this case, the Saved Photos ) First create the function for the Image Picker:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
        
        var x = CGFloat(arc4random_uniform(100)+50)
        var y = CGFloat(arc4random_uniform(100)+50)
        
        
        
        var image = info[UIImagePickerControllerOriginalImage] as UIImage // create a variable from the image
        var imageViewNew = UIImageView(frame: CGRectMake(100, 100, 150 , 150)) // creating a new UIImageView for the image once loaded on the screen
        
        
        imageViewNew.center = CGPoint(x: x, y: y)
        
        imageViewNew.image = image
        
        imageView.addSubview(imageViewNew) // add the newly created UIImageView to the main Imageview Subview
        
        
        imageViewNew.multipleTouchEnabled = true
        imageViewNew.userInteractionEnabled = true // UIImageView by default has these disabled
        
        
        
        createPanGestureRecognizer(imageViewNew)
        createPinchGestureRecognizer(imageViewNew)    // adding gesture to the newly created image ? Keep in mind you have to create these functions separately.
        createRotateGestureRecognizer(imageViewNew)
        
        
        
        dismissViewControllerAnimated(true, completion: nil)
        
    }

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

var x = CGFloat(arc4random_uniform(100)+50)

var y = CGFloat(arc4random_uniform(100)+50)

var image = info[UIImagePickerControllerOriginalImage] as UIImage // create a variable from the image

var imageViewNew = UIImageView(frame: CGRectMake(100, 100, 150 , 150)) // creating a new UIImageView for the image once loaded on the screen

imageViewNew.center = CGPoint(x: x, y: y)

imageViewNew.image = image

imageView.addSubview(imageViewNew) // add the newly created UIImageView to the main Imageview Subview

imageViewNew.multipleTouchEnabled = true

imageViewNew.userInteractionEnabled = true // UIImageView by default has these disabled

createPanGestureRecognizer(imageViewNew)

createPinchGestureRecognizer(imageViewNew) // adding gesture to the newly created image ? Keep in mind you have to create these functions separately.

createRotateGestureRecognizer(imageViewNew)

dismissViewControllerAnimated(true, completion: nil)

}

Then this is what we are actually gonna tie up to our button for loading an image:

@IBAction func imageButtonPressed(sender: AnyObject) {
        
        
        
        
        
        var imagePicker = UIImagePickerController()
        var sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
        
        if UIImagePickerController.isSourceTypeAvailable(sourceType) {
            
            imagePicker.sourceType = sourceType
            
            imagePicker.delegate = self
            
            //        show a screen
            
            
            presentViewController(imagePicker, animated: true, completion: nil)
        }

        
        
    }

var sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum

if UIImagePickerController.isSourceTypeAvailable(sourceType) {

imagePicker.sourceType = sourceType

imagePicker.delegate = self

// show a screen

presentViewController(imagePicker, animated: true, completion: nil)

}
