使用Swift从您的应用程序向WhatsApp发送消息？ [英] Sending message to WhatsApp from your app using Swift?

问题描述

对于我的某个应用，我想与WhatsApp联系人分享数据。我在StackOverflow上尝试了一些解决方案，但无法获得精确的解决方案。经过一些试验可以达到我想要的目的，所以在这里分享给任何人未来的参考。

For one of my app, I wanted to share data to WhatsApp contacts. I tried few solutions overs the StackOverflow but couldn't get exact solution. After some trials could achieve what I was looking for, so sharing here for anyone's future reference.

推荐答案

 var url  = NSURL(string: "whatsapp://send?text=Hello%20Friends%2C%20Sharing%20some%20data%20here...%20!")

//Text which will be shared on WhatsApp is: "Hello Friends, Sharing some data here... !"

    if UIApplication.sharedApplication().canOpenURL(url!) {
        UIApplication.sharedApplication().open(url as URL, options: [:]) { (success) in
                if success {
                    print("WhatsApp accessed successfully")
                } else {
                    print("Error accessing WhatsApp")
                }
            }
    }

注意：文本需要进行URL编码。您可以使用互联网上的任何开源工具或在iOS中使用addsPercentEncoding（withAllowedCharacters :)功能来获取它。
例如。

Note: text needs to be URL encoded. You can get it using any of the open source tools over internet or using addingPercentEncoding(withAllowedCharacters:) function in iOS. e.g.

var urlString = "Hello Friends, Sharing some data here... !"
var urlStringEncoded = urlString.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)
var url  = NSURL(string: "whatsapp://send?text=\(urlStringEncoded!)")
