我的一个应用程序需要将数据分享给WhatsApp联系人。我在StackOverflow上尝试了几个解决方案,但都没有得到确切的解决方案。经过一些尝试,我终于实现了我想要的目标,并在此分享给各位以供参考。
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: 文本需要进行URL编码。你可以使用任何开源工具在互联网上获取它,或者在iOS中使用addingPercentEncoding(withAllowedCharacters:)函数。 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!)")
Swift 5
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")
}
}
}
Swift 3.0
尝试使用以下代码在您的应用程序中访问 WhatsApp,这对我来说完美地运作。
@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")
}
}
}
}
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")
}
工作很好,但当我放置这个URL时
("http://www.proprofs.com/quiz-school/story.php?title=pq-find-out-which-ice-age-character-you-are ")
如果它没有起作用,请检查一下,谢谢。感激您的帮助。
let urlStringEncoded = urlString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
if let URL = URL(string: urlStringEncoded!), UIApplication.shared.canOpenURL(URL as URL) {
UIApplication.shared.open(URL, options: [:], completionHandler: nil)
}else{
Utility.showToast("Whatsapp未安装。")
}

请按照以下步骤通过URL Scheme分享到WhatsApp:
<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")
}
}
}
}
愉快的编码!
