iOS9 saving bug.

[ghost]

I've been using this library for a while and since I got it working correctly I haven't had any issues.

However, now I'm noticing on iOS 9 (now running WKWebView instead of UIWebView, not sure if that makes a difference), that when I save, it saves to my custom album, camera roll (not a problem as that's supposed to happen), but it saves to a Screenshot folder as well.

Tested in iOS 8 simulator, no screenshot folder.

Is this a iOS 9 issue? Library issue? WKWebView issue?

Thanks for any feedback.

Hi @ChrisOSX this lib won't try to take a screenshot, it uses system SDK to take photo & save it to custom album.

I just tried in iOS 9.2 (13C75), w/o anything wrong. :)

Just took these 2 simulator screenshots of iOS 8.4 and 9.2 to show the comparison.

Can u offer the code snippet u used to save the photo? Including the part like to generate / resize the image.

[ghost]

This is how I'm calling it in my file.

        NSURL *imageURL = self.imageInfo.imageURL;
        UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:imageURL]];

        // The completion block to be executed after image taking action process done
        void (^completion)(NSURL *, NSError *) = ^(NSURL *assetURL, NSError *error) {
            if (error) NSLog(@"!!!ERROR,  write the image data to the assets library (camera roll): %@",
                             [error description]);
            NSLog(@"*** URL %@ | %@ || type: %@ ***", assetURL, image, [assetURL class]);

        };

        void (^failure)(NSError *) = ^(NSError *error) {
            if (error == nil) return;
            NSLog(@"!!!ERROR, failed to add the asset to the custom photo album: %@", [error description]);
        };

        [self.assetsLibrary saveImage:image
                              toAlbum:kKYCustomPhotoAlbumName
                           completion:completion
                              failure:failure];

What about the code snippet to generate self.imageInfo?

[ghost]

I'm using JTSImageViewController. It has quite a few files.

Not sure about it, just checked its demo, seems okay. Can u offer the code snippet u used to generate self.imageInfo? Any other lib u used related to image taking?

[ghost]

self.imageInfo is generated by that library. It's it own .h and .m files then linked to the other library files.

I don't use any other lib for image taking, other than this one.

My action sheet is triggered by a long press gesture, and one button is for saving, where this library comes into play.

This is how the image gets called in my view controller. The code recognizes a link "example.png", fires the image controller, then ends with the above.

        // Create image info
       NSURLRequest *request = navigationAction.request;
       fileURL = request.URL;

        JTSImageInfo *imageInfo = [[JTSImageInfo alloc] init];
        imageInfo.imageURL = fileURL;

        // Setup view controller
        JTSImageViewController *imageViewer = [[JTSImageViewController alloc]
                                               initWithImageInfo:imageInfo
                                               mode:JTSImageViewControllerMode_Image
                                               backgroundStyle:JTSImageViewControllerBackgroundOption_Blurred];

        // Present the view controller.
        [imageViewer showFromViewController:self transition:JTSImageViewControllerTransition_FromOffscreen];

Seems this part is ok, JTSImageInfo instance just stores image related data. No idea then, sorry, it's hard for me to debug w/o a testing project, i'd glad to offer more help if u can give me a simple demo project that can reproduce the issue (just upload it as ur own repo).

I suggest u do not use two libs (or any other 3rd party lib) at same time first, and test to c which one generates the screenshot actually. e.g., don't use ALAssetsLibrary-CustomPhotoAlbum lib, just save it to normal album to c whether the screenshot still appear.

Btw, have u tried this lib's demo, does the screenshot appear as well in ur device?

Let me know if u're pretty sure it's indeed lead by this lib, thx :)

So with some troubleshooting and using an older version of my project (which uses a different image viewer), I can determine that the new image viewer isn't really to blame, but how I loaded the image and calling the save action. I renamed some things in the save function. did a full clean and such and then tested it out on my device. No screenshot folder.

I had a feeling it was that, but none the less I appreciate the quick feedback and help. This is a awesome library!

@ChrisOSX good, glad to hear that :)
