How to load photos from photo gallery and store it into application project?

Question

I'm working on an application that is almost the same as the sample codes i found here. But the method i want to do is different from the sample codes.
Link: PhotoLocations

The first screen will have an ImageView and 2 buttons (Choose Photo, Confirm). When the 'Choose Photo' button is tapped, it will navigate to another screen which retrieves photos from my iPad's photo gallery. When a photo is chosen, it will dismiss the current screen and return to the first screen displaying the chosen photo on the ImageView.

When the 'Confirm' button is tapped, the photo will be stored into my application's project (eg /resources/images/photo.jpg).

May i know how can i do this?

Answer 1

This will take you to the image gallery and you can select the image.

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc]init];
imagePickerController.delegate = self;
imagePickerController.sourceType =  UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePickerController animated:YES completion:nil];

this will help you select the image

- (void)imagePickerController:(UIImagePickerController *)picker 
    didFinishPickingImage:(UIImage *)image
              editingInfo:(NSDictionary *)editingInfo
{
    // Dismiss the image selection, hide the picker and

    //show the image view with the picked image

    [picker dismissViewControllerAnimated:YES completion:nil];
    //UIImage *newImage = image;
}

And then you can store this image to the documents directory...

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];

For clicking the image yourself use this

- (IBAction) takePhoto:(id) sender
{
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

    imagePickerController.delegate = self;
    imagePickerController.sourceType =  UIImagePickerControllerSourceTypeCamera;

    [self presentModalViewController:imagePickerController animated:YES];
}

Answer 2

UIImagePickerController *cardPicker = [[UIImagePickerController alloc]init];
cardPicker.allowsEditing=YES;
cardPicker.delegate=self;
cardPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController:appDelegate.cardPicker animated:YES];
[cardPicker release];

And this delegate method will return the image u select from the album

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo 
{
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
    noImage.image=img;
}

 - (IBAction)UploadPhoto:(id)sender { UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Please Select Your Option"delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Camera", @"Gallery",nil]; [actionSheet showInView:self.view]; UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview]; NSIndexPath *clickedButtonPath = [jobstable indexPathForCell:clickedCell]; isSectionIndex = clickedButtonPath.section; isRowIndex = clickedButtonPath.row; } -(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{ NSLog(@"From didDismissWithButtonIndex - Selected Option: %@", [actionSheet buttonTitleAtIndex:buttonIndex]); NSString*image=[actionSheet buttonTitleAtIndex:buttonIndex]; if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Camera"]) { if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { UIAlertView* alert = [[UIAlertView alloc] initWithTitle:nil message:@"Device Camera Is Not Working" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil]; [alert show]; return; } else{ UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.allowsEditing = YES; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentViewController:picker animated:YES completion:NULL]; } } else if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Gallery"]){ UIImagePickerController *pickerView = [[UIImagePickerController alloc] init]; pickerView.allowsEditing = YES; pickerView.delegate = self; [pickerView setSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum]; [self presentViewController:pickerView animated:YES completion:nil]; } } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{ UIImage* orginalImage = [info objectForKey:UIImagePickerControllerOriginalImage]; NSIndexPath *indexPath = [NSIndexPath indexPathForRow:isRowIndex inSection:isSectionIndex]; UITableViewCell *cell = [jobstable cellForRowAtIndexPath:indexPath]; UIImageView *tableIMAGE=(UIImageView *)[cell.contentView viewWithTag:19]; tableIMAGE.image=orginalImage; answersARRAY[indexPath.row] = [NSString stringWithFormat:@"-1,%@,%@,",answersARRAY[indexPath.row],imageStris]; [self dismissViewControllerAnimated:YES completion:nil]; } - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { [picker dismissViewControllerAnimated:YES completion:NULL]; }
