ios – 如何在Swift中加载GIF图像?

我有一个带有GIF横幅的字符串,我需要将其放入应用程序。

我的代码:

func showAdd(){
    Request.get("http://www.kyst.no/api/?apiMode=advertisement&lang=no", { (error: NSError?, data: NSData, text: NSString?) -> () in
        let jsonResult: Dictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as Dictionary<String, AnyObject>
        var banner : NSString = jsonResult["advertisement"]!["banner"] as NSString
        self.addViewImage.image = UIImage.animatedImageNamed(banner, duration: 1)
    })
}

但没有任何反应。请帮忙。

#1:使用名称加载GIF图像

    let jeremyGif = UIImage.gifImageWithName("funny")
    let imageView = UIImageView(image: jeremyGif)
    imageView.frame = CGRect(x: 20.0, y: 50.0, width: self.view.frame.size.width - 40, height: 150.0)
    view.addSubview(imageView)

#2:使用数据加载GIF图像

    let imageData = try? Data(contentsOf: Bundle.main.url(forResource: "play", withExtension: "gif")!)
    let advTimeGif = UIImage.gifImageWithData(imageData!)
    let imageView2 = UIImageView(image: advTimeGif)
    imageView2.frame = CGRect(x: 20.0, y: 220.0, width: 
    self.view.frame.size.width - 40, height: 150.0)
    view.addSubview(imageView2)

#3:使用URL加载GIF图像

    let gifURL : String = "http://www.gifbin.com/bin/4802swswsw04.gif"
    let imageURL = UIImage.gifImageWithURL(gifURL)
    let imageView3 = UIImageView(image: imageURL)
    imageView3.frame = CGRect(x: 20.0, y: 390.0, width: self.view.frame.size.width - 40, height: 150.0)
