Well you can do it simply by following next steps:
Add the following functions
#import <ImageIO/ImageIO.h>
#import <MobileCoreServices/MobileCoreServices.h>
UIImage *GIFFromData(NSData *data) {
if (!data) {
return nil;
}
CGImageSourceRef source = CGImageSourceCreateWithData((__bridge CFDataRef)(data), NULL);
UIImage *image = nil;
if (GIFSourceContainsAnimatedGIF(source)) {
image = GIFFromImageSource(source);
} else {
image = [UIImage imageWithData:data];
}
if (source) {
CFRelease(source);
}
return image;
}
BOOL GIFSourceContainsAnimatedGIF(CGImageSourceRef source) {
return (source && UTTypeConformsTo(CGImageSourceGetType(source), kUTTypeGIF) && CGImageSourceGetCount(source) > 1);
}
UIImage *GIFFromImageSource(CGImageSourceRef source) {
CFRetain(source);
NSUInteger numberOfFrames = CGImageSourceGetCount(source);
NSMutableArray<UIImage *> *images = [NSMutableArray arrayWithCapacity:numberOfFrames];
NSTimeInterval duration = 0.0;
for (NSUInteger i = 0; i < numberOfFrames; ++i) {
CGImageRef image = CGImageSourceCreateImageAtIndex(source, i, NULL);
if (image) {
UIImage *frameImage = [UIImage imageWithCGImage:image scale:1.0 orientation:UIImageOrientationUp];
[images addObject:frameImage];
CFRelease(image);
} else {
continue;
}
duration += GIFSourceGetFrameDelay(source, i);
}
CFRelease(source);
return [UIImage animatedImageWithImages:images duration:duration];
}
NSTimeInterval GIFSourceGetFrameDelay(CGImageSourceRef source, NSUInteger index) {
NSTimeInterval frameDelay = 0;
CFDictionaryRef imageProperties = CGImageSourceCopyPropertiesAtIndex(source, index, NULL);
if (!imageProperties) {
return frameDelay;
}
CFDictionaryRef gifProperties = nil;
if (CFDictionaryGetValueIfPresent(imageProperties, kCGImagePropertyGIFDictionary, (const void **)&gifProperties)) {
const void *durationValue = nil;
if (CFDictionaryGetValueIfPresent(gifProperties, kCGImagePropertyGIFUnclampedDelayTime, &durationValue)) {
frameDelay = [(__bridge NSNumber *)durationValue doubleValue];
if (frameDelay <= 0) {
if (CFDictionaryGetValueIfPresent(gifProperties, kCGImagePropertyGIFDelayTime, &durationValue)) {
frameDelay = [(__bridge NSNumber *)durationValue doubleValue];
}
}
}
}
CFRelease(imageProperties);
return frameDelay;
}
Download your GIF with NSURLSession
Display it
UIImage *image = GIFFromData(data);
UIImageView *view = [[UIImageView alloc] initWithImage:image];
Hope this helps :)

UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
animatedImageView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"image1.gif"],
[UIImage imageNamed:#"image2.gif"],
[UIImage imageNamed:#"image3.gif"],
[UIImage imageNamed:#"image4.gif"], nil];
animatedImageView.animationDuration = 1.0f;
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
[self.view addSubview: animatedImageView];
