原生方法:

1.UIWebView
特點:加載速度略長,性能更優，播放的gif動態圖更加流暢。

//動態展示GIF圖片-WebView
-(void)showGifImageWithWebView{
    //讀取gif圖片數據
    NSData *gifData = [NSData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"earthGif" ofType:@"gif"]];
    //UIWebView生成
    UIWebView *imageWebView = [[UIWebView alloc] initWithFrame:CGRectMake(112, 302, 132, 102)];
    //用戶不可交互
    imageWebView.userInteractionEnabled = NO;
    //加載gif數據
    [imageWebView loadData:gifData MIMEType:@"image/gif" textEncodingName:nil baseURL:nil];
    //視圖添加此gif控件
    [self.view addSubview:imageWebView];
}

2.UIImagView
加載的方式更加快速,性能不如UIWebView,優點:易於擴展

1)
增加一個UIImageView的類別(category),增加兩個方法
UIImage+Tool
.h

#import 

@interface UIImageView (Tool)

/** 解析gif文件數據的方法 block中會將解析的數據傳遞出來 */
-(void)getGifImageWithUrk:(NSURL *)url returnData:(void(^)(NSArray * imageArray,NSArray*timeArray,CGFloat totalTime, NSArray* widths, NSArray* heights))dataBlock;

/** 為UIImageView添加一個設置gif圖內容的方法： */
-(void)yh_setImage:(NSURL *)imageUrl;

@end

@implementation UIImageView (Tool)



//解析gif文件數據的方法 block中會將解析的數據傳遞出來
-(void)getGifImageWithUrk:(NSURL *)url returnData:(void(^)(NSArray * imageArray, NSArray*timeArray,CGFloat totalTime, NSArray* widths,NSArray* heights))dataBlock{
    //通過文件的url來將gif文件讀取為圖片數據引用
    CGImageSourceRef source = CGImageSourceCreateWithURL((CFURLRef)url, NULL);
    //獲取gif文件中圖片的個數
    size_t count = CGImageSourceGetCount(source);
    //定義一個變量記錄gif播放一輪的時間
    float allTime=0;
    //存放所有圖片
    NSMutableArray * imageArray = [[NSMutableArray alloc]init];
    //存放每一幀播放的時間
    NSMutableArray * timeArray = [[NSMutableArray alloc]init];
    //存放每張圖片的寬度 （一般在一個gif文件中，所有圖片尺寸都會一樣）
    NSMutableArray * widthArray = [[NSMutableArray alloc]init];
    //存放每張圖片的高度
    NSMutableArray * heightArray = [[NSMutableArray alloc]init];
    //遍歷
    for (size_t i=0; i *imageArray, NSArray *timeArray, CGFloat totalTime, NSArray *widths, NSArray *heights) {
        //添加幀動畫
        CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"contents"];
        NSMutableArray * times = [[NSMutableArray alloc]init];
        float currentTime = 0;
        //設置每一幀的時間占比
        for (int i=0; i

在加載gif的地方使用
導入 UIImageView+Tool

-(void)showGifImageWithImageView{

    UIImageView * imageView = [[UIImageView alloc]initWithFrame:CGRectMake(112, 342, 132, 102)];
    NSURL * url = [[NSURL alloc]initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"earthGif.gif" ofType:nil]];
    [imageView yh_setImage:url];
    [self.view addSubview:imageView];

}

第三方:
1.YLGIFImage
github鏈接: https://github.com/liyong03/YLGIFImage

#import "YLGIFImage.h"
#import "YLImageView.h"

-(void)showGifImageWithYLImageView{
    YLImageView* imageView = [[YLImageView alloc] initWithFrame:CGRectMake(112, 342, 132, 102)];
    CGFloat centerX = self.view.center.x;
    [imageView setCenter:CGPointMake(centerX, 402)];
    [self.view addSubview:imageView];
    imageView.image = [YLGIFImage imageNamed:@"earthGif.gif"];
}

2.FLAnimatedImage
github鏈接:https://github.com/Flipboard/FLAnimatedImage

-(void)showGifImageWithFLAnimatedImage{
    //GIF 轉 NSData
    //Gif 路徑
    NSString *pathForFile = [[NSBundle mainBundle] pathForResource: @"earthGif" ofType:@"gif"];
    //轉成NSData
    NSData *dataOfGif = [NSData dataWithContentsOfFile: pathForFile];
    //初始化FLAnimatedImage對象
    FLAnimatedImage *image = [FLAnimatedImage animatedImageWithGIFData:dataOfGif];
    //初始化FLAnimatedImageView對象
    FLAnimatedImageView *imageView = [[FLAnimatedImageView alloc] init];
    //設置GIF圖片
    imageView.animatedImage = image;
    imageView.frame = CGRectMake(112, 342, 132, 102);
    [self.view addSubview:imageView];
}
