Saving image to Documents directory and retrieving for email attachment
email, ios, iphone, nsdocument
Solution
- (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!
Problem
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"]; ```
