我有一个带有GIF横幅URL的字符串,需要将其放入应用程序中。
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)
})
}
但是什么也没发生。请帮忙。
加载GIF图像Swift:
#1:从此链接复制swift文件:
#2: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)
#3: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)
#4: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)
view.addSubview(imageView3)
输出:
iPhone 8 / iOS 11 / xCode 9
