Comment charger des photos de la galerie de photos et les stocker dans un projet d'application?

Je travaille sur une application qui est presque identique aux exemples de codes que j'ai trouvés ici. Mais la méthode que je veux faire est différente des exemples de codes.
Lien: PhotoLocations

Le premier écran aura un ImageView et 2 boutons (Choisissez Photo, Confirmer). Lorsque vous appuyez sur le bouton "Choisir une photo", vous accédez à un autre écran qui récupère les photos de la galerie de photos de mon iPad. Lorsqu'une photo est choisie, elle ferme l'écran actuel et revient au premier écran affichant la photo choisie sur ImageView.

Lorsque vous appuyez sur le bouton "Confirmer", la photo est stockée dans le projet de mon application (par exemple, /resources/images/photo.jpg).

Puis-je savoir comment puis-je faire cela?

Cela vous mènera à la galerie d'images et vous pourrez sélectionner l'image.

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

cela vous aidera à choisir l'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;
}

Et puis vous pouvez stocker cette image dans le répertoire de documents ...

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];

Pour cliquer vous-même sur l'image, utilisez cette

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

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

    [self presentModalViewController:imagePickerController animated:YES];
}

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

Et cette méthode déléguée renverra l'image que vous aurez sélectionnée dans l'album.

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