Safari有一个“添加至屏幕”的功能，其实就是在桌面上添加了一个网页书签，App可以使用这个功能来实现创建桌面快捷方式。
<!-- 一、运用基本技术点 -->
JavaScript
Data URI Schema
Socket基本知识
Base64编码
<!-- 二、基本原理 -->
程序内部创建一个简单的Web站点，通过这个站点调用Safari，站点将自定义的Html页面返回给Safari，此时利用Safari的“添加至主屏幕”功能，将自定义的Html制作成桌面书签，当用户点击桌面图标时，则运行自定义的Javascript来进行跳转至App。
<!-- 三、什么是 data URI scheme？节省了一个 HTTP 请求 -->
直接把图像的内容崁入网页里面，这个密技的官方名称是 data URI schema
<!-- Data URI scheme 的语法 -->
data – 取得数据的协定名称
image/png – 数据类型名称
base64 – 数据的编码方法
iVBOR…. – 编码后的数据
: , ; – data URI scheme 指定的分隔符号
<!-- 四、什么是 Base64 编码？ -->
把一些 8-bit 数据翻译成标准 ASCII 字符
<!-- 五、Socket基本知识 -->
使用CocoaHttpServer创建一个本地的站点
https://github.com/robbiehanson/CocoaHTTPServer
_httpServer = [[HTTPServer alloc] init];
[_httpServer setType:@"_http._tcp."];
NSString *webPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Web"];
// DDLogInfo(@"Setting document root: %@", webPath);
[_httpServer setDocumentRoot:webPath];
[self startServer];
<!-- 创建HttpServer -->
- (void)startServer
{
// Start the server (and check for problems)
NSError *error;
if([_httpServer start:&error])
{
DDLogInfo(@"Started HTTP Server on port %hu", [_httpServer listeningPort]);
// open the url.
NSString *urlStrWithPort = [NSString stringWithFormat:@"http://localhost:%d",[_httpServer listeningPort]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStrWithPort]];
}
else
{
DDLogError(@"Error starting HTTP Server: %@", error);
}
}
<!-- 六、实现 -->
<!-- [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStrWithPort]]; -->
https://developer.apple.com/library/ios/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html
1) 检测Web应用程序当前是否运行在全屏状态，只要检测window.navigator.standalone是否为true就可以了
2) 检测到Web应用程序运行在非全屏状态时就可以提示用户把Web应用程序的图标添加到主屏幕。
3) http://software.hixie.ch/utilities/cgi/data/data

<!-- 如果非全屏，那么我们显示引导页，如果是全屏，我们就打开一个链接 -->
涉及：OpenUrl、iOS shceme、Data URI Scheme、JS、Socket#
<!-- 在Safari中，有一个功能叫：添加到主屏幕，而我们将使用这个入口去实现这个功能。 -->
<!-- [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"tel://xxx"]]; -->
<!-- JS -->
<script>
if (window.navigator.standalone == true)
{
// 全屏状态的时候 模拟点击事件，即打开app---webKit---通过快捷方式打开的Safari是全屏的
var lnk = document.getElementById("你的带scheme的<a>标签ID").click();
//通过你所知道的方式打开一个scheme，上面这句话的链接标签如：<a href="tel://xxx">
}
else
{
document.getElementById("msg").innerHTML='<div style="font-size:12px">
可以插入引导页</div>';
//这里你可以去加载你的引导页
}
</script>
<!-- 通过DataURI，我们可以把图片进行base64编码直接存储在页面中 -->
