Is It possible to access photo editing extension from my app

Question

I am making an iOS app for photos and stores photos locally inside my app. I have to edit some photos. So, I have to write a lot of code to do exactly like apple photos app does. Instead of writing the code myself is there any possible way to access iPhone photos app, just for editing from my app. And is it possible to use extensions to access photos editing features? Thanks In advance!

I don't exactly what do you mean by extension but you can access the photo library using UIImagePickerController (Here's the class reference https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIImagePickerController_Class/ and the sample code https://developer.apple.com/library/prerelease/ios/samplecode/PhotoPicker/Introduction/Intro.html). And you can allow editing like follows

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
     [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
} else {
    [imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}

[imagePicker setAllowsEditing:YES];
[imagePicker setDelegate:self];
