JMAnimatedImageView

JMAnimatedImageView is a performant subclass of UIImageView:

• Plays huge image animation using a minimum memory pressure,
• Allows manual interactions with imageView to drive manualy animations,
• Can use has a Carousel,
• GIF are supported to load your animations.

Change Log

0.2.4 :

• Improve documentation
• Fix retain cycle (Thanks Instruments!)
• JMGif allocation for a better integration with your favorites network libraries.

Installation

Simply replace your UIImageView instances with instances of JMAnimatedImageView.

If using CocoaPods, the quickest way to try it out is to type this on the command line:

$ pod try JMAnimatedImageView

Usage

For a local animation using file from a bundle

In your code, #import "JMAnimatedImageView.h" and #import "JMAnimatedImageView.h"

//GIF example
@property (weak, nonatomic) IBOutlet JMAnimatedImageView *jmImageView;

[self.jmImageView reloadAnimationImagesFromGifNamed:@"rock"];
self.jmImageView.animationType = JMAnimatedImageViewAnimationTypeAutomaticLinearWithoutTransition;
[self.jmImageView startAnimating];

//PNG example with manual animation
@property (weak, nonatomic) IBOutlet JMAnimatedImageView *jmImageView;

self.jmImageView.animationDelegate = self;
self.jmImageView.animationDatasource = self;
[self.jmImageView reloadAnimationImages]; //<JMOImageViewAnimationDatasource>
self.jmImageView.animationType = JMAnimatedImageViewAnimationTypeAutomaticLinearWithoutTransition;
self.jmImageView.memoryManagementOption = JMAnimatedImageViewMemoryLoadImageLowMemoryUsage;
[self.jmImageView startAnimating];

For a remote Gif

@property (weak, nonatomic) IBOutlet JMAnimatedImageView *jmImageView;

[[JMApi sharedApi] downloadYourGifFileHasData:^(NSData *gifData) {
	self.animatedImageView.animationType = JMAnimatedImageViewAnimationTypeAutomaticLinearWithoutTransition;
    self.animatedImageView.memoryManagementOption = JMAnimatedImageViewMemoryLoadImageLowMemoryUsage;
   	[self.animatedImageView reloadAnimationImagesFromGifData:gifData fromUrl:url];
     [self.animatedImageView startAnimating];
}];	

For a remote Gif using AFNetworking

    NSURLRequest *req = [NSURLRequest requestWithURL:url];
	
    AFHTTPRequestOperation *postOperation = [[AFHTTPRequestOperation alloc] initWithRequest:req];
    [postOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
		self.animatedImageView.animationType = JMAnimatedImageViewAnimationTypeAutomaticLinearWithoutTransition;
    	self.animatedImageView.memoryManagementOption = JMAnimatedImageViewMemoryLoadImageLowMemoryUsage;
   		[self.animatedImageView reloadAnimationImagesFromGifData:responseObject fromUrl:url];
     	[self.animatedImageView startAnimating];

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Image error: %@", error);
        block(NO, nil);
    }];
    
	[postOperation start];

Customizations

• AnimationType

typedef NS_ENUM(NSUInteger, JMAnimatedImageViewAnimationType) {
    JMAnimatedImageViewAnimationTypeInteractive = 0,
    
    //Animation, carousel effect
    JMAnimatedImageViewAnimationTypeManualSwipe,
    
    //Automatic rotation, use animationDuration + animationRepeatCount
    JMAnimatedImageViewAnimationTypeAutomaticLinear,    
    JMAnimatedImageViewAnimationTypeAutomaticLinearWithoutTransition,
    JMAnimatedImageViewAnimationTypeAutomaticReverse,
};

• MemoryOption

typedef NS_ENUM(NSUInteger, JMAnimatedImageViewMemoryOption) {
    JMAnimatedImageViewMemoryLoadImageSystemCache = 0,  //images memory will be retain by system
    JMAnimatedImageViewMemoryLoadImageLowMemoryUsage,   //images loaded but not retained by the system
    JMAnimatedImageViewMemoryLoadImageCustom            //images loaded by you (JMOImageViewAnimationDatasource)
};

• ImageViewOrder

typedef NS_ENUM(NSUInteger, JMAnimatedImageViewOrder) {
    JMAnimatedImageViewOrderNormal = 1,
    JMAnimatedImageViewOrderReverse = -1
};

Multi Gif and animation type (top interactive, leff automatic swipe effect, right automatic without animation)

JMimageView can generate Carousels

JMimageView allows interactive animations

TODO

• Add support for APNG
• Add support for WebP animated (work in progress but this feature is not actually supported : https://chromium.googlesource.com/webm/libwebp/)
• • Add support for video format ?
