Example of creating an animated GIF on iOS, with no 3rd-party code required. This should also be easy to port to OS X.

	#import <UIKit/UIKit.h>
	#import <ImageIO/ImageIO.h>
	#import <MobileCoreServices/MobileCoreServices.h>

	static UIImage *frameImage(CGSize size, CGFloat radians) {
	UIGraphicsBeginImageContextWithOptions(size, YES, 1); {
	[[UIColor whiteColor] setFill];
	UIRectFill(CGRectInfinite);
	CGContextRef gc = UIGraphicsGetCurrentContext();
	CGContextTranslateCTM(gc, size.width / 2, size.height / 2);
