如何在 Swift 3中发送消息并链接到WhatsApp

我正在使用此代码：
??Code

消息错误到控制台：

…failed for URL: “whatsapp://send?text=Check” – error: “This app is
not allowed to query for scheme whatsapp”

谢谢

解决方法

你应该试试这个：

注意：您必须在设备中安装whatsapp app.

斯威夫特3

var documentInteractionController: UIDocumentInteractionController = UIDocumentInteractionController()

@IBAction func whatsappShareText(_ sender: AnyObject)
{
    let originalString = "First Whatsapp Share"
    let escapedString = originalString.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed)

    let url  = URL(string: "whatsapp://send?text=(escapedString!)")

    if UIApplication.shared.canOpenURL(url! as URL)
    {
        UIApplication.shared.open(url! as URL,options: [:],completionHandler: nil)
    }
}

@IBAction func whatsappShareLink(_ sender: AnyObject)
{
    let originalString = "https://www.google.co.in"
    let escapedString = originalString.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed)
    let url  = URL(string: "whatsapp://send?text=(escapedString!)")

    if UIApplication.shared.canOpenURL(url! as URL)
    {
        UIApplication.shared.open(url! as URL,completionHandler: nil)
    }
}

在您的应用“info.plist”中添加此代码

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>whatsapp</string>
</array>
