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.经过一些试验可以实现我想要的,所以在这里分享给任何人的未来参考.

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.您可以通过互联网使用任何开源工具或在iOS中使用addsPercentEncoding(withAllowedCharacters :)功能来获取它.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!)")

Answer 2

Swift 3.0

尝试使用此代码访问应用程序中的watsapp.它非常适合我.

@IBAction func sendButtonAction(_ sender: Any)
{
    let date = Date()
    let msg = "Hi my dear friends\(date)"
    let urlWhats = "whatsapp://send?text=\(msg)"

    if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed) {
        if let whatsappURL = NSURL(string: urlString) {
            if UIApplication.shared.canOpenURL(whatsappURL as URL) {
                UIApplication.shared.openURL(whatsappURL as URL)
            } else {
                print("please install watsapp")
            }
        }
    }
}

Answer 3

Addition to above solutions, starting from iOS 9, we need to add whatsapp to LSApplicationQueriesSchemes key in info.plist. After this only it worked for me.
