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 NSDocumentDirectoy and then want to retrieve it for attaching to an email,

Here the saving code:

- (IBAction)saveImage {     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);     NSString *documentsDirectory = [paths objectAtIndex:0];     NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:@"savedImage.png"];     UIImage *image = imageView.image; // imageView is my image from camera     NSData *imageData = UIImagePNGRepresentation(image);     [imageData writeToFile:savedImagePath atomically:NO];    } 

Here is the new getting data code:

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);     NSString *documentsDirectory = [paths objectAtIndex:0];     NSString *appFile = [documentsDirectory stringByAppendingPathComponent:@"savedImage.png"];     NSData *myData = [[[NSData alloc] initWithContentsOfFile:appFile] autorelease];     [picker addAttachmentData:myData mimeType:@"image/png" fileName:@"savedImage"]; 

Answer 1

- (IBAction)getImage {     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);     NSString *documentsDirectory = [paths objectAtIndex:0];     NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:@"savedImage.png"];     UIImage *img = [UIImage imageWithContentsOfFile:getImagePath]; } 

This should get you started!

Answer 2

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.
