ios - 使用 Swift 从您的应用程序向 WhatsApp 发送消息？

Question

对于我的一个应用程序，我想与 WhatsApp 联系人共享数据。我在 StackOverflow 上尝试了几种解决方案，但无法获得确切的解决方案。经过一些尝试可以达到我想要的效果，所以在这里分享以供大家日后引用。

Answer 1

 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 addingPercentEncoding(withAllowedCharacters:) 函数来获取它。例如

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