To download images from web service:
从网络服务下载图像：
NSData *imageData = [NSData dataWithContentsOfURL:"*Url from web service*"];
UIImage *imageOne = [UIImage imageWithData:imageData];
likely download all images from web service and create an array like:
可能从网络服务下载所有图像并创建一个数组，如：
NSArray *imagesArray = [NSArray arrayWithObjects:imageOne...........,nil];
and use with little modification:
只需稍加修改即可使用：
UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
animatedImageView.animationImages = imagesArray;
animatedImageView.animationDuration = 1.0f;
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
[self.view addSubview: animatedImageView];

self.imgView.animationRepeatCount = 1 // IF Require once set this 1, 0 == infinite

@IBOutlet weak var imgview: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()

self.imgview.animationDuration = 10.0
self.imgview.animationRepeatCount = 0
self.imgview.startAnimating()
