Loading spinner before image loads

[nkhaitan]

Hello,

Is there a way we could have a progress spinner show up before the image loads completely?

Thanks,

Nilesh

Hi, @nkhaitan, no, unfortunately the slideshow does not show a spinner right now.

This will a good feature to add. Feel free to submit a pull request. It can be done by adding a new settings property:

scrollView.auk.settings.showSpinnerWhileLoading = true

I personally prefer placeholder images.

// Show placeholder image while remote image is being downloaded.
scrollView.auk.settings.placeholderImage = UIImage(named: "placeholder.jpg")

You can see how it works and looks in the demo app.

Thanks a lot man! Will look into it. Also, is there a way I can add a button on the bottom right of each image?

@nkhaitan, yes, it can be done. Each page in the scroll view is an instance of AukPage class which is a UIView subclass.

You can fork the library and add other subviews such as buttons into it. What we can also do is expose a public property that contains those pages in the form of UIViews, something like this:

let slideshowPages = scrollView.auk.pages // Array of UIView objects
slideshowPages[0].addSubview(button) // Add a button to the page of the slideshow
// Position the button with Auto Layout on the bottom right.

This will make it easier for other people to add subviews to pages without a need to maintain their own fork of the library. Feel free to submit a pull request with the pages property. There is already a helper method that returns the array of pages AukScrollViewContent.aukPages(scrollView: UIScrollView). It returns an array of AukPage objects. I would prefer to cast it to UIView before returning them to the user from the public pages property.
