//GIF 用第三方库

(1)

//获得图片路径

//通过指定路径下的文件初始化NSData

UIImageView *imgView=[[UIImageView alloc]initWithFrame:CGRectMake(100,100,50,50)];

imgView.image=[UIImage animatedImageWithAnimatedGIFData:data];

[self.window addSubview:imgView];

(2)

NSURL *url=[[NSBundle mainBundle]URLForResource:@"FlagZombie" withExtension:@"gif"];

UIImageView *imgView=[[UIImageView alloc]initWithFrame:CGRectMake(200,100,80,80)];

//通过类别中的方法animatedImageWithAnimatedGIFURL实现Gif的图片的播放

imgView.imge=[UIImage animatedImageWithAnimatedGIFURL:url];

imgView.tag=100;

[self.window addSubview:imgView];

//通过定时器实现每一段时间调用move方法

[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(move) userInfo:nil repeats:YES];

-(void)move{
UIImageView *imgView=(UIImageView *)[self.window viewWithTag:100];

//当图片的x坐标大于80,没调用move都使图片向左侧偏移5个单位

if(imgView.frame.origin.x>80){
imgView.frame=CGRectMake(imgView.frame.origin.x-5,imgView.frame.origin.y,imgView.frame.size.width,imgView.frame.size.height);
