Saving image to Documents directory and retrieving for email attachment

Question

I having trouble figuring out NSBundle & DocumentDirectory data, I have a Camera Picture \"imageView\" that I\'m saving to the NSDocumentDire

Answer 1

Swift 3

// Create a URL
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first
let imageURL = documentsURL?.appendingPathComponent("MyImageName.png")

// save image to URL
let myImage = imageView.image! // or wherever you have your UIImage

do {
    try UIImagePNGRepresentation(myImage)?.write(to: imageURL!)
} catch {}


// Use the URL to retrieve the image for sharing to email, social media, etc.
// docController.URL = imageURL
// ...

I force unwrapped some of the optionals for brevity. Use guard or if let in your code.
