depthlove / makeAnimatedGif.m

Created June 5, 2018 10:37 — forked from mayoff/makeAnimatedGif.m

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);

depthlove / UIImage+Scale.m

Created December 19, 2017 05:22 — forked from tomasbasham/UIImage+Scale.m

Scale a UIImage to any given rect keeping the aspect ratio

	@implementation UIImage (scale)

	/**
	* Scales an image to fit within a bounds with a size governed by
	* the passed size. Also keeps the aspect ratio.
	*
	* Switch MIN to MAX for aspect fill instead of fit.
	*
	* @param newSize the size of the bounds the image must fit within.
	* @return a new scaled image.
