我想在我的应用中打开一个whatsapp网址,如。
let whatsAppUrl = NSURL(string: "whatsapp://send?text=Hello%2C%20World!")
if UIApplication.sharedApplication().canOpenURL(whatsAppUrl!) {
UIApplication.sharedApplication().openURL(whatsAppUrl!)
}
我使用字典“LSApplicationQueriesSchemes”扩展我的info.plist并为whatsapp添加我的url方案。
<key>LSApplicationQueriesSchemes</key>
<dict>
<key>Item 0</key>
<string>whatsapp</string>
</dict>
如果我运行我的应用程序,我会收到以下错误消息。
"This app is not allowed to query for scheme whatsapp"
我阅读了一些清理衍生数据的解决方案,然后再次运行应用来解决此问题。但这对我没有帮助,对我的问题存在另一种解决方案吗?

您已将LSApplicationQueriesSchemes设为dict
,必须是数组,如this,然后它将起作用:)。
<key>LSApplicationQueriesSchemes</key>
<array>
<string>whatsapp</string>
</array>
我还建议您不要使用!
打开可选网址,您可以这样做:
guard
let whatsAppUrl = URL(string: "whatsapp://send?text=Hello%2C%20World!"),
case let application = UIApplication.shared,
application.canOpenURL(whatsAppUrl)
else { return }
application.openURL(whatsAppUrl)

let url = "whatsapp://send?text=Hello World!"
if let urlString = url.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()) {
if let whatsappURL = NSURL(string: urlString) {
if UIApplication.sharedApplication().canOpenURL(whatsappURL) {
UIApplication.sharedApplication().openURL(whatsappURL)
}
}}
并定义类似
的查询方案<key>LSApplicationQueriesSchemes</key>
<array>
<string>whatsapp</string>
</array>
