Get last image from Photos.app?

Question

I have seen other apps do it where you can import the last photo from the Photos app for quick use but as far as I know, I only know how to get A image and not the last (mos

iBrad's example includes an iOS8 snippet that apparently works, but I found myself confused by the return type he described. Here is a snippet that grabs the last image, including options for version and size requirements.

Of note are the ability to request a specific version (original, current) and size. In my case, as I wish to apply the returned image to a button, I request it sized and scaled to fit the button I'm applying it to:

PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]];
PHFetchResult *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
PHAsset *lastAsset = [fetchResult lastObject];
[[PHImageManager defaultManager] requestImageForAsset:lastAsset
                                          targetSize:self.photoLibraryButton.bounds.size
                                         contentMode:PHImageContentModeAspectFill
                                             options:PHImageRequestOptionsVersionCurrent
                                       resultHandler:^(UIImage *result, NSDictionary *info) {

                                           dispatch_async(dispatch_get_main_queue(), ^{

                                               [[self photoLibraryButton] setImage:result forState:UIControlStateNormal];

                                           });
                                       }];
