-(void)dealloc

{

    [self.window release];

    [super dealloc];

}

-(void)createImageView

{

 
  //首先创建一个UIImageView的对象

 
  UIImageView *
imageView = [[UIImageView alloc]initWithFrame:[[UIScreen mainScreen] bounds]];

 
  //imageView.image =[UIImage
imageNamed:@""];

 
  //如果图片所占内存比较大
用以上方法添加的图片会发存放在应用程序中 占用系统的活跃内存 
系统的活跃内存是有限的 所以存放图片如果很大 不建议使用以上方法

 
  //NSBundle 路径类

 
  //[NSBundle mainBundle] 获取的是当前工程的路径

 
  //pathForResource:获取某个资源
第一个参数添加的是查找的资源的名称 第二个参数是资源的后缀名

 
  NSString *
path = [[NSBundle
mainBundle]
pathForResource:@"cat_eat0000" ofType:@"jpg"];

 
  //每次使用的图片的时候都会直接到路径下获取
然后不存放在活跃内存中 虽然效率很低 但是很安全 不会因为获取内存不足报警告 
或程序崩溃

   UIImage * image1 = [UIImage imageWithContentsOfFile:path];

    

    imageView.image = image1;

    

 
  NSMutableArray * arr = [[NSMutableArray alloc]init];

 
  //将所有图片添加到数组里

   for(int
i = 0;i<<span
style="color: #272ad8">40;i++)

    {

   
    NSString *
string = [[NSBundle
mainBundle]
pathForResource:[NSString stringWithFormat:@"cat_eat00%.2d",i] ofType:@"jpg"];

     
 UIImage *
image = [UIImage imageWithContentsOfFile:string];

     
  [arr addObject:image];

    }

    [self.window addSubview:imageView];

    

 
  //当前的imageView与用户进行交互

   
imageView.userInteractionEnabled = YES;

 
  //UIImageVeiw 与UILabel
都是不能与用户交互
所以要将userInteractionEnabled设为yes以后才可进行交互

    

 
  //1、为当前的imageView
添加一组图片（数组中存放的就是图片的对象指针）

    [imageView setAnimationImages:arr];

 
  //2、动画时间

   
[imageView setAnimationDuration:3];

 
  //3、设置动画的显示次数(-1表示无限循环)

   
[imageView setAnimationRepeatCount:-1];

 
  //4、动画开始

    [imageView startAnimating];

    

 
  //5、动画停止的方法

 
  //点击手势类

 
  UITapGestureRecognizer * tap = [[UITapGestureRecognizer
alloc]initWithTarget:self
action:@selector(stop:)];

    

 
  //设置点击的次数

   
tap.numberOfTapsRequired = 1;

 
  //几根手指点击

   
tap.numberOfTouchesRequired = 2;

 
  //将点击事件添加到imageView上

    [imageView addGestureRecognizer:tap];

    

    

    

}

-(void)stop:(UITapGestureRecognizer * )recognizer

{

 
  //通过手势
查找添加了手势的视图

    [((UIImageView *)recognizer.view) stopAnimating];

 
  //stopAnimating停止动画
