iOS9:如果可能，尝试通过方案打开应用程序，否则重定向到应用程序商店 [英] iOS9: Try to open app via scheme if possible, or redirect to app store otherwise

问题描述

我的问题是关于 iOS9 的！

我有一个 HTML 登录页面，如果应用已安装，我尝试通过 URL 架构将用户重定向到我的应用，或者重定向到 应用商店否则.

I have an HTML landing page, and I try to redirect the user to my app via URL scheme if the app is installed, or redirect to the Appstore otherwise.

我的代码是:

document.addEventListener("DOMContentLoaded", function(event) {

  var body = document.getElementsByTagName('body')[0];
  body.onclick = function () {
    openApp();
  };
});

var timeout;

function preventPopup() {

    clearTimeout(timeout);
    timeout = null;
    window.removeEventListener('pagehide', preventPopup);
}

function openApp(appInstanceId, platform) {

  window.addEventListener('pagehide', preventPopup);
  document.addEventListener('pagehide', preventPopup);

  // create iframe
  var iframe = document.createElement("iframe");
  document.body.appendChild(iframe);
  iframe.setAttribute("style", "display:none;");
  iframe.src = 'myscheme://launch?var=val';

  var timeoutTime = 1000;
  timeout = setTimeout(function () {

    document.location = 'https://itunes.apple.com/app/my-app';

  }, timeoutTime);
}

问题是 iframe 技巧在 Safari iOS9 中不起作用.

The problem is that the iframe trick doesn't work in Safari iOS9.

知道为什么吗?

推荐答案

iframe 技巧不再有效——我猜测 Apple 知道它将鼓励更多开发人员更快地实施通用链接.

The iframe trick no longer works -- my guess is that Apple knows it will encourage more developers to implement Universal Links, more quickly.

您仍然可以设置 window.location='your-uri-scheme://'; 并在 500 毫秒后回退到 App Store.如果您采用这种方法，弹出窗口之间会出现跳舞"，就像我们在 Branch 所做的那样(如果 Universal链接无效).

You can still set window.location='your-uri-scheme://'; and fallback to the App Store after 500ms. There is a "dance" between popups if you take this approach, as we do at Branch (we do as a fallback if Universal Links don't work).

window.location = 'your-uri-scheme://'; // will result in error message if app not installed
setTimeout(function() {
   // Link to the App Store should go here -- only fires if deep link fails                
   window.location = "https://itunes.apple.com/us/app/myapp/id123456789?ls=1&mt=8";
}, 500);

我希望我有一个更好的答案给你.iOS 9 肯定更受限制.

I wish I had a better answer for you. iOS 9 is definitely more limited.
