Convert UIImage to NSData and save with core data

Question

I have a UIImageView whose image gets set via UIImagePicker

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPi         


        

Answer 1

Here is what I have done and its working for storing to nsdata.

[productTypeSub setValue:[[NSData alloc] initWithContentsOfURL:[NSURL  URLWithString:url]] forKey:@"imgSmall"];

and loading to image with this code

ImgProductType.image= [[UIImage alloc] initWithData:productTypeSub.imgSmall];

Answer 2

You can convert a UIImage to NSData like this:

If PNG image

UIImage *image = [UIImage imageNamed:@"imageName.png"];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)];

If JPG image

UIImage *image = [UIImage imageNamed:@"imageName.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);

You can store it in CoreData like so (this is one possible useful solution):

[newManagedObject setValue:imageData forKey:@"image"];

You can load the data from CoreData like this:

NSManagedObject *selectedObject = [[self yourFetchCOntroller] objectAtIndexPath:indexPath];
UIImage *image = [UIImage imageWithData:[selectedObject valueForKey:@"image"]];

// Set the image to your image view  
yourimageView.image = image;
