尝试打开未安装的本机应用程序时如何防止iOS safari警报？ [英] how to prevent iOS safari alert when trying to open non-installed native app?

问题描述

我一直在寻找一种从浏览器打开原生iOS应用的方法。
我在这里找到了一个不错的解决方案：是否可以为YouTube应用程序（如YouTube和地图）注册基于http +域的URL方案？

I've been looking for a way to open a native iOS app from the browser. I found a decent solution here: Is it possible to register a http+domain-based URL Scheme for iPhone apps, like YouTube and Maps?

当您安装了应用程序时，此解决方案非常有用。但是当用户没有安装此应用程序时 - safari将触发一条错误消息，指出Safari无法打开该页面，因为该地址无效。

This solution works great when you have the app installed. but when a user doesn't have this app installed - safari fires an error message which says "Safari cannot open the page because the address is invalid."

是否有防止这种行为的方法，而不是提示用户下载应用程序？

Is there a way to prevent this behaviour and instead to prompt the user to download the app?

推荐答案

这是一个适合我的解决方案：

Here is a solution that works for me:

var timeout;

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

function openApp() {    
    $('<iframe />')
    .attr('src', appurl)
    .attr('style', 'display:none;')
    .appendTo('body');

    timeout = setTimeout(function() {
            document.location = appstore;
    }, 500);
    window.addEventListener('pagehide', preventPopup);
}
