WARNING - CONSIDER THIS CODEBASE DEPRECATED. TAKE A LOOK AT: IPDFCameraViewController

MAImagePickerController aka. InstaOverlay

MAImagePickerController is a critical component of the InstaPDF (http://instapdf.me) for iPhone app. I've started to code in Objective C a couple of months ago, so please offer your insights into making the component better.

Final/Adjusting View

Using it in your project

  1. Add all the necessary files inside MAImagePicker to your Project
  2. #import "MAImagePickerController.h" in your ViewController's header (.h) file & declare that it can be delegated by MAImagePickerControllerDelegate
  3. IMPORTANT: This project uses the OpenCV framework. Download the newest version here: 'http://opencv.org/'
  4. Double check all the necessary frameworks: 'CoreImage.framework', 'opencv2.framework', 'QuartzCore.framework', 'ImageIO.framework', 'CoreMedia.framework', 'AVFoundation.framework', MediaPlayer.framework
  5. The API is rather simple, use it like this:
- (IBAction)initButton:(id)sender
{
    MAImagePickerController *imagePicker = [[MAImagePickerController alloc] init];

    [imagePicker setDelegate:self];
    [imagePicker setSourceType:MAImagePickerControllerSourceTypeCamera];

    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:imagePicker];

    [self presentViewController:navigationController animated:YES completion:nil];
}

- (void)imagePickerDidCancel
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)imagePickerDidChooseImageWithPath:(NSString *)path
{
    [self dismissViewControllerAnimated:YES completion:nil];

    if ([[NSFileManager defaultManager] fileExistsAtPath:path])
    {
        NSLog(@"File Found at %@", path);

    }
    else
    {
        NSLog(@"No File Found at %@", path);
    }

    [[NSFileManager defaultManager] removeItemAtPath:path error:nil];
}
