ThumbnailPickerView

ThumbnailPickerView is a control displaying a set (or technically an array) of thumbnails aligned horizontally. It mimics thumbnails view from iPad's Photos.app toolbar, but as a subclass of UIControl it can be freely used as a regular view outside the toolbar.

Features

• selecting thumbnails by touch or programmatically - big thumbnail view overlays selected thumbnail
• touch-tracking of user selection (support for both tapping and panning through thumbnails)
• autoadjusting amount of visible thumbnails to nicely fit within view bounds
• loading data from the data source, interacting with outside world through the delegate
• asynchronous image loading
• reusable image views
• ARC-enabled code

Usage

See the demo application for usage example.

Requirements

• QuartzCore framework (solely for drawing borders around thumbnails)
• XCode 4.2 (for ARC)
