I having trouble figuring out NSBundle
& DocumentDirectory data, I have a Camera Picture \"imageView\" that I\'m saving to the NSDocumentDire
Try this one :
-(void)setProfilePic
{
NSArray *docpaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [docpaths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"Image.png"];
NSData *imgData = [[NSData alloc] initWithContentsOfURL:[NSURL fileURLWithPath:imagePath]];
UIImage *thumbNail = [[UIImage alloc] initWithData:imgData];
[profilePic_btn setBackgroundImage:thumbNail forState:UIControlStateNormal];
}
Because each iPhone app is in it's own sandbox, you don't have access to a device-wide documents folder. To attach an image to an email, save the image in your own documents folder. Try using [@"~/Documents" StringByExpandingTildeInPath] to get your local documents folder - that works for me. It looks like the technique you're using for attaching the image to an email is correct.
Hope that helps,
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.
- (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!
