#Leaves

Leaves is an animated interface for navigating through a sequence of images using page-turning gestures. As of iOS 5, Leaves is mostly obsoleted by UIPageViewController.

Leaves requires iOS 3.0 or later.

##Installation

1. Add the files in the Leaves subdirectory to your Xcode project.
2. Ensure that your target links against QuartzCore.framework.

##Usage

Creating a page-turning view controller is as simple as subclassing LeavesViewController:

#import "LeavesViewController.h"
@interface ColorSwatchViewController : LeavesViewController 
@end

...and implementing the LeavesViewDataSource protocol:

@implementation ColorSwatchViewController
- (NSUInteger)numberOfPagesInLeavesView:(LeavesView*)leavesView { 
 return 10;
}
- (void)renderPageAtIndex:(NSUInteger)index inContext:(CGContextRef)context { 
 CGContextSetFillColorWithColor(
 context, 
 [[UIColor colorWithHue:index/10.0 
 saturation:0.8 
 brightness:0.8 
 alpha:1.0] CGColor]);
 CGContextFillRect(ctx, CGContextGetClipBoundingBox(ctx));
}
@end

You may also use LeavesView directly. For more examples, see the included LeavesExamples project.
