[英]How can I send message to specific contact through WhatsApp from my ios app using swift?
[英]Sending message to WhatsApp from your app using Swift?
对于我的一个应用程序,我想将数据分享给 WhatsApp 联系人。 我在 StackOverflow 上尝试了一些解决方案,但无法获得确切的解决方案。 经过一些试验可以实现我想要的,所以在这里分享以供任何人将来参考。
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:文本需要经过 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 addPercentEncoding(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!)")

尝试使用此代码在您的应用程序中访问 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")
}
}
}
}

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")
}
}
}
我的代码看起来像这样
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")
}
工作正常但是当我把这个网址
("http://www.proprofs.com/quiz-school/story.php?title=pq-find-out-which-ice-age-character-you-are ")
然后它不工作请检查Thanks.HelpWill Be Appriciated。

请按照以下步骤通过 URL Schemes 在 WhatsApp 上共享
<key>LSApplicationQueriesSchemes</key> <array> <string>whatsapp</string> </array>
代码
@IBAction func whatsappShareText(_ sender: AnyObject) {
let message = "First Whatsapp Share & https://www.google.co.in"
var queryCharSet = NSCharacterSet.urlQueryAllowed
// if your text message contains special characters like **+ and &** then add this line
queryCharSet.remove(charactersIn: "+&")
if let escapedString = message.addingPercentEncoding(withAllowedCharacters: queryCharSet) {
if let whatsappURL = URL(string: "whatsapp://send?text=\(escapedString)") {
if UIApplication.shared.canOpenURL(whatsappURL) {
UIApplication.shared.open(whatsappURL, options: [: ], completionHandler: nil)
} else {
debugPrint("please install WhatsApp")
}
}
}
}
快乐编码!
