如何解决嵌入式Instagram帖子的大小
我按照以下说明（https://developers.facebook.com/docs/instagram/oembed/）将instagram照片嵌入到我的iOS Swift应用程序中。但是，instagram帖子不符合文档中承诺的容器宽度：
嵌入式帖子具有响应能力，将适应其大小 容器。这意味着高度将根据 容器的宽度和标题的长度。您可以设置最大 通过将maxwidth查询字符串参数包含在您的 请求。
具体地说，帖子的右侧有一个大的白色区域。
您能告诉我我想念的是什么吗？
这是我的代码：
import UIKit
import WebKit
class ViewController: UIViewController {
@IBOutlet var webView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()

Her collections “Ma Petit Inuite” and “Arctic Charade” (pictured) confronts the impact of humans’ behavior on our planet and the effects of climate change. “I am driven by my irritation of how we are treating the globe,like tourism at Antarctica and the Arctic and mining for resources in those particular areas which are so vital for the balance in the world,” says Preta,who incorporates embroidery,sequins,acrylics and leather into her work. “I love to use acrobats in my work,who seem to stand for joyfulness,carelessness,sparkle,like what tourism looks like on first sight. People need entertainment and they see the world as one big amusement park. The acrobats stand for the foolish behavior of mankind ruining its environment,which now even threatens to spread out to the last untouched areas of our planet: the North and South Pole. I think it’s better that people get my message through humor and joyfulness. It can be serious,humorous and aesthetic at the same time.” #ThisWeekOnInstagram Art by @pretawolzak</a></p> <p style=\" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;\">A post shared by <a href=\"https://www.instagram.com/instagram/?utm_source=ig_embed&utm_campaign=loading\" style=\" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px;\" target=\"_blank\"> Instagram</a> (@instagram) on <time style=\" font-family:Arial,sans-serif; font-size:14px; line-height:17px;\" datetime=\"2020-10-14T16:08:29+00:00\">Oct 14,2020 at 9:08am PDT</time></p></div></blockquote>\n<script async src=\"//platform.instagram.com/en_US/embeds.js\"></script>"

解决方法
我也遇到了这个问题。对我来说，问题是oEmbed的html需要用<HTML>标签包裹在<HEAD>和<meta>标签中。
这是一个例子：
func loadHTMLContent(_ htmlContent: String) {
let htmlStart = "<HTML><HEAD><meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,shrink-to-fit=no\"></HEAD><BODY>"
let htmlEnd = "</BODY></HTML>"
let htmlString = "\(htmlStart)\(htmlContent)\(htmlEnd)"
webView.loadHTMLString(htmlString,baseURL: "https://instagram.com")
}
注意：我没有将embeds.js脚本添加到webView。
