Photo/Image Viewer for Monotouch [closed]

Question

I've googled a bit but could not find a simple Image Viewer class to use in my MonoTouch app.

I don't need to show image thumbnails neither a complete photo album (with multiple photos).

I just need an image viewer to show an UIImageView, allowing the common fullscreen/zoom operations.

Obviously such viewer could be implemented using a UIViewController subclass with UIGestureRecognizer, UIScrollView and UINavigationBar trickery, but I don't want to reinvent the wheel. Does anyone know about an open source component available ?

It would also be useful to host such component in the new Xamarin Component Store

Thanks

Answer 1

Here it is.

Features:

• Show both big images (larger than the screen) and small ones;
• One tap to close view, two taps to zoom in/out. Pinch to zoom is also available;
• Scrolling through available content. It's impossible to scroll image outside visible area. Thanks to UIScrollView's ContentSize property.

Suggestions for future:

• I reduced code by removing UINavigationBar usage.
• Also it's nice to add UIView's basic animation (fade in/out) when user opens/closes full screen image view.

Some relative info:

• Solution was strongly inspired by this article.
• As a starting point for patching I recommend Xamarin's article.

Any bug reports and suggestions are welcome!
