iOS-Senior17-Gif动画图片(代码)

Posted 2020-07-13 萌萌的周丽娜

自己先手动拖进工程一组图片，以.tiff为后缀的

//创建一个显示图片的imageview

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

    [self.view addSubview:showGIFImage];

    //创建一个存储图片的数组

    NSMutableArray *saveArray = [NSMutableArray array];

    for (int i = 1; i < 6; i++) {

        NSString *imageName = [NSString stringWithFormat:@"%d.tiff",i];

        UIImage *image = [UIImage imageNamed:imageName];

        [saveArray addObject:image];

    }

    //设置GIF图片组

    showGIFImage.animationImages = saveArray;

    //设置播放速率

    showGIFImage.animationDuration = 1.0f;

    //设置播放次数（设置动图图重复的次数）[-1为无限次播放]

    showGIFImage.animationRepeatCount = -1;

    //动图需要设置开启

    [showGIFImage startAnimating];
