IPHONE GIF播放的方式

１.UIWebView 播放（无法控制周期）

@inte易做图ce webViewController : UIViewController {
IBOutlet UIWebView *WebView;
IBOutlet UINavigationBar *Nav;
}
@property (nonatomic, retain) IBOutlet UIWebView *WebView;
@end

- (void)viewDidLoad {
    [super viewDidLoad];
    [WebView setOpaque:NO];
    [WebView setBackgroundColor:[UIColor clearColor]];
    Nav.topItem.title=@"Welcome";
    Nav.topItem.leftBarButtonItem=nil;
    NSString* gifFileName = @"j_0002.gif";
    NSMutableString* htmlStr = [NSMutableString string];
    [htmlStr appendString:@"Hello Honey"];
    [htmlStr appendString:@"<p><img src=\""];
    [htmlStr appendFormat:@"%@",gifFileName];
    [htmlStr appendString:@"\" alt=\"picture\"/>"];
    [WebView loadHTMLString:htmlStr baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]]];

2.glgif提供的开源代码实现（目前无法控制周期，需要自己再研究）

3.使用UIView的animation接口实现（GIF需要整理出每张图片）

动画可以用UIImageView，把动画的每一帧做成图片，转换成UIImage保存在animationImages数组中，调用- (void)startAnimating;就能看到动画

4.把GIF的通过GIF的格式转换成每张图片，通过UIView的animation的接口实现（GIF的格式貌似还是有问题，有部分图片的背景有问题）

    NSURL *threeUrl =[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"crad"
                                                                            ofType:@"gif"]];
    NSData* data = [[NSData alloc]initWithContentsOfURL:threeUrl];
    NSMutableArray* array = nil;
// long word = ::SizeofResource(handle,hrsrc);
// char* lpBy = (char*)LoadResource(handle,hrsrc);
    DWORD word = data.length;
    BYTE* lpBy = (BYTE*)data.bytes;
    //每张图保存的指针需要释放
    BYTE* pByte[100] = {0};
    //每张图的大小
    DWORD nu[100] = {0};
    //图片数量
    int num = 0;
    DWORD firstLocation = 0;
    for(DWORD j=0;j<word;j++)
    {
        if(lpBy[j]==0x2c)
        {
            if(lpBy[j-1]==0x00)
            {
                if(num==0)
                {
                    firstLocation = j;
                }

                if (num== 10)
                {
                    int sdf=nu[num];
                    int sdfadf=0;
                }

                PGifImage nowImage = (PGifImage)&lpBy[j+1];

                if(nowImage->Flag.a==0)
                {
                    DWORD number = 1+sizeof(GifImage);
                    while(lpBy[j+number]!=0)
                    {
                        number = number+(DWORD)lpBy[j+number]+1;
                    }
                    number++;
                    pByte[num] = new BYTE[number];
                    memset(pByte[num],0,number);
                    for(DWORD n=0;n<number;n++)
                    {
                        *(BYTE*)(pByte[num]+n) = lpBy[j+n];
                    }
                    nu[num] = number;
                    j = j+number-1;
                    num++;
