A subclass of UIView that will load most common media formats and display in the appropriate view. This is helpful when implementing a gallery of media in tiles when the type of media can be mixed or is unknown.
The following formats are implemented:
- Static images (UIImageView)
- Animated GIF (FLAnimatedImage)
- Video (AVPlayer)
Include PRGalleryView.swift and use the PRGalleryView UIView in a storyboard
or in code. Media can be loaded via an NSURL using the media attribute:
let gallery: PRGalleryView = PRGalleryView(frame: CGRectMake(0, 0, 250, 250))
gallery.media = NSURL(string: "http://raphaelschaad.com/static/nyan.gif")
The type of media object will be determined and displayed in the view.
Access to each of the view layers is available at imageView and
videoController for further customization of the view behavior. This can be
used to, among other things, set view clipping and background colors to ensure
the gallery display matches your requirements.
The type of loaded media can be accessed at PRGalleryView.type. This will
return a PRGalleryType of either Video, Animated, or Image.
Lastly, control over playback of animated GIF and Video files are available
with play(), pause(), and stop(). By default, animated GIF images will be
loaded in a playing state.
Video and GIF files can be locked to a static representation by setting the
shouldAllowPlayback value to false. For videos, this will display a static
frame from the video file. This is useful for a gallery of thumbnails where
playback is not necessary. You can start and stop playback from the static state
using the methods above. In this case, when stop() is called on a Video where
shouldAllowPlayback is false, the video is replaced with the static frame.
