ios开发：图片连续动画

    //获取图片路径:相对路径
    //第一个参数：文件的名字
    //第二个参数：文件的类型
    NSString *path = [[NSBundle mainBundle] pathForResource:@"map" ofType:@"png"];
    UIImage *imagePath = [UIImage imageWithContentsOfFile:path];
    UIImageView *imageViewPath = [[UIImageView alloc] initWithFrame:CGRectMake(20, 130, 200, 50)];
    imageViewPath.image = imagePath;
        /****动画效果相关属性****/
    //创建图片数组
    //开辟内存空间
    NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:0];
    for (int i = 1; i <= 12; i ++) {
        [array addObject:[UIImage imageNamed:[NSString stringWithFormat:@"player%d.png",i]]];
    }
    //设置动画图片，需要接收一个数组，数组里面的类型必须是UIImage类型
    imageView.animationImages = array;
    //动画时间：数组里面所有的图片转一圈所用时间
    imageView.animationDuration = 1;
    //循环次数：大于0的数：写几就循环几次，结束    0:无限循环
    imageView.animationRepeatCount = 0;
 //开始动画
    [imageView startAnimating];
  //按钮点击开始或结束
  static BOOL isAnimation = YES;//static静态变量用过立即释放
    if (isAnimation)
    {//等价于isAnimation为真(isAnimation==YES)
        [imageView stopAnimating];
        isAnimation = NO;
        //这时的isAnimation=YES被释放为空,接着
        //赋值为NO再次点击按钮时isAnimation=NO;
    }
    else
    {
        [imageView startAnimating];
        isAnimation = YES;
    }
//定时器
    [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(birdFly:) userInfo:nil repeats:YES];
