【代码笔记】iOS-利用图片序列创建动态图片效果

一，效果图。

二，代码。

RootViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    //显示图片的UIImageView
    UIImageView *imageview=[[UIImageView alloc]initWithFrame:CGRectMake(50, 100, 200, 200)];
    imageview.backgroundColor=[UIColor redColor];
    [self.view addSubview:imageview];

    //动画的实现
    NSMutableArray * images = [NSMutableArray arrayWithCapacity:6];
    for (int i = 1; i <= 6; i++)
    {
        NSString * imageName = [NSString stringWithFormat:@"%d.jpg",i];
        UIImage * image = [UIImage imageNamed:imageName];

        [images addObject:image];
    }
    imageview.animationImages = images;
    imageview.animationDuration = 0.3;
    [imageview startAnimating];

}
