Xcode-Saving the image from the photo library for further use

I am trying to make a simple application using XCode 4.5 which would allow the user to chose any particular image via accessing his photo library, then submit that image for recognition with the help of the Tesseract library.

The problem is that I do not know how to further save the selected user picture, In other words, I can provide the user with an option for going in the picture library and let him chose a picture, but I do not how to then save that selected picture so that it can be further processed.

I hope i made it clear, Appreciate your help.

I am still not clear about what exactly you want. You can always Save Image in or Retrieve Image from Photo Library.

What you need to do is save the image data after selection inside the following delegate - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { You can get the image via the key UIImagePickerControllerOriginalImage in the info dictionary and possibly assign it to an imageview or save it as mentioned by @Kalpesh. Check out apple's documentation for more info. Also check out this good tutorial that shows how to pick photos from the photo album or the camera.

Try this, Save image: 

NSString *imgName=[@"imgname.png"];
[[NSUserDefaults standardUserDefaults]setValue:imgName forKey:@"imageName"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:imgName];
UIImage *image = imageView.image; // imageView is my image from camera
NSData *imageData = UIImagePNGRepresentation(image);
[imageData writeToFile:savedImagePath atomically:NO];

Retrive image:

NSString *imgName= [[NSUserDefaults standardUserDefaults]valueForKey:@"imageName"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
NSString *filePath=[NSString stringWithFormat:@"%@/%@",documentsDir,imageName];
[imageview setImage:[UIImage imageWithContentsOfFile:filePath]];
