How can I set a custom image in UIIMagePickerController

I have UIActionSheet with 3 options -

  1. Take a photo (from camera)
  2. Choose from library
  3. Edit photo (if user has profile picture )

I use UIImagePickerController and don't have problems with first 2 options. User choose photo and then can zoom/move to crop one.

So, my question is - how I can put already saved photo for editing (3rd option) with current scale factor and frame. F.e if I choose "edit photo" I want to get the same photo "state" that I've choosen after preview.

That is how native "contacts" app works!

photo's preview

You need to access the UIImagePickerControllerEditedImage object in your delegate method:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
    if (!image) image = [info objectForKey:UIImagePickerControllerOriginalImage];
    ....
}

Then you can use this image in your own edit view controller. The Contacts app works this way because it writes the edited image back to the ALAsset, a destructive change. It is probably a bad idea to do this for users in your app, so it is best to write your own edit image controller that will handle the edited image instead of UIImagePickerController. A search on github shows tons of open-source repos that can help you with cropping here.
