Answer 1

从班级let urlString = "https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=AUD" let url = URL(string: urlString) URLSession.shared.dataTask(with:url!) { (data, response, error) in if error != nil { print(error as Any) } else { do { let parsedData = try JSONSerialization.jsonObject(with: data!) as! [String:Any] let id = parsedData["id"] as! [String:Any] print(id) } catch let error as NSError { print(error) } } }.resume()

中删除opacity: 0;

新代码：

element-to-animate

Answer 2

你有一个动画，每个动画都有一个间隔。 如果你想要循环你必须设置的动画

 animation-iteration-count: 1;

Answer 3

在所有关键帧中将0％的不透明度值从0更换为1。

在您的班级animation-fill-mode: forwards

中添加.element-to-animate媒体资源

    .element-to-animate {
    -webkit-animation: NAME-YOUR-ANIMATION 10s forwards;
    -moz-animation: NAME-YOUR-ANIMATION 10s forwards;
    -o-animation: NAME-YOUR-ANIMATION 10s forwards;
    animation: NAME-YOUR-ANIMATION 10s forwards;
    opacity:0;
}
