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

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.

Whe开发者_Go百科n the 'Confirm' button is tapped, the photo will be stored into my application's project (e.g. /resources/images/photo.jpg).

May i know how can i do this?

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];
}

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;
}
