1:不能有注释,

2:需要三个重要文件(.ipa,.plist,png).ipa文件就是应用程序文件,
.plist文件是苹果需要通过itms-services协议访问的文件。png是图片的大小512*512,57*57两张

3:ipa,plist,png在服务器同一个目录存放
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD

4:调用方式: 
(1)我们在网页的head标签中加入JS代码,当用户访问网页的时候自动触发,进行下载。 <script> var url =
"https://demo.abc.com/myapp/manifest.plist"; window.location =
"itms-services://?action=download-manifest&url=" + url; </script>
2.以web链接的形式,当用户点击触发a标签的时候进行下载 <a
href="itms-services://?action=download-manifest&url=https://www.某某网址/manifest.plist">点击下载</a>
