Ios 使用Swift从应用程序向WhatsApp发送消息？

对于我的一个应用程序，我想与WhatsApp联系人共享数据。我在StackOverflow上尝试了几个解决方案，但没有得到确切的解决方案。经过一些试验可以达到我所期待的，所以在这里分享给任何人的未来参考

 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URL编码。您可以使用internet上的任何开源工具或使用iOS中的addingPercentEncoding（withAllowedCharacters:）函数来获取它。 e、 g

我的代码是这样的

let encodeQuizStr = "Check Out The Quiz With link \n http://www.proprofs.com "

        let urlQuizStringEncoded = encodeQuizStr.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)

        guard let whatsAppUrl = NSURL(string: "whatsapp://send?text="+urlQuizStringEncoded!) else { return }

        if UIApplication.shared.canOpenURL(whatsAppUrl as URL) {

            if #available(iOS 10.0, *) {
                print(urlQuizStringEncoded!)
                UIApplication.shared.open(whatsAppUrl as URL, options: [:], completionHandler: nil)
            } else {

                UIApplication.shared.openURL(whatsAppUrl as URL)

            }
        }
        else{


            ProjectUtility.AlertWith(self, message: " What's App is Not Available.", Title: "Sorry")
        }

工作正常，但当我把这个网址

("http://www.proprofs.com/quiz-school/story.php?title=pq-find-out-which-ice-age-character-you-are ")

那么它不工作了，请检查一下，谢谢。我们会通知您帮助。

Swift 3.0

请尝试使用此代码在应用程序中访问watsapp。这对我来说非常有效

@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")
            }
        }
    }
}

除了上述解决方案之外，从iOS 9开始，我们需要将whatsapp添加到info.plist中的LSApplicationQueriesSchemes密钥中。在这之后，只有它对我有效

代码

let urlWhats = "whatsapp://send?text=\("Hello World")"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed) {
      if let whatsappURL = NSURL(string: urlString) {
            if UIApplication.shared.canOpenURL(whatsappURL as URL) {
                 UIApplication.shared.open(whatsappURL as URL)
             } 
             else {
                 print("please install watsapp")
             }
      }
}

请按照以下步骤通过URL方案在WhatsApp上共享

在应用程序“info.plist”中添加此代码

Hi@Pandurang亚克瓦德。我如何分享一个链接？你能给我演示一下吗。请。或者，当我试图共享www.Google.com时，我们是否可以共享一个Url长度，但我的Url太长，所以我的文本区域变为空白。@AvinashMishra我认为Url长度没有任何限制。只需检查该url是否直接在浏览器中工作。有时错误的url会导致问题。在浏览器中工作正常，不在此处。@AvinashMishra如果您共享代码，我可以查看并让您知道问题所在。是否有字符限制？是否有字符限制？您提到我必须发送消息的号码的地方？？？让urlString=”whatsapp://send?text=" + （self.modelForScreen？.deeplinkattransation？？？）如果让URL=URL（字符串：urlStringEncoded！），则让urlStringEncoded=urlString.addingPercentEncoding（允许字符：.UrlQueryLowed），UIApplication.shared.canOpenURL（URL为URL）{UIApplication.shared.open（URL，选项：[：]，completionHandler:nil）}else{Utility.showtoos（“Whatsapp未安装”）}

let urlWhats = "whatsapp://send?text=\("Hello World")"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed) {
      if let whatsappURL = NSURL(string: urlString) {
            if UIApplication.shared.canOpenURL(whatsappURL as URL) {
                 UIApplication.shared.open(whatsappURL as URL)
             } 
             else {
                 print("please install watsapp")
             }
      }
}
