Optimization

1. Reuse cells (like UITableView).
2. Cache images (both memory and disk layers).
3. Use thumbs instead of original images.

Other features

1. Change data source for images dynamically.
2. Set number of columns dynamically.
3. Reload images at the end of user dragging, instead of decelerating.
4. Return index of tapped image.

How to use it

1. Link binary with libraries: MapKit.framework, ImageIO.framework.
2. Add the IIIThumbFlow folder to your project.
3. Implement the IIIFlowViewDelegate methods in your view controller:
   - (NSInteger)numberOfColumns;
- (NSInteger)numberOfCells;
- (CGFloat)rateOfCache;
- (IIIFlowCell *)flowView:(IIIFlowView *)flow cellAtIndex:(int)index;
- (IIIBaseData *)dataSourceAtIndex:(int)index;

Check out IIIFlowViewDelegate for more information.

Requirements

IIIThumbFlow uses ARC. If you are not using ARC in your project, add '-fobjc-arc' as a compiler flag for all the files in IIIThumbFlow.

Included libraries

IIIThumbFlow uses SDWebImage v2.0 to cache images. The author has done really great job on performance and memory usage optimization about images.
