通过WhatsApp URL方案作为文本传递URL

Question

我想通过WhatsApp URL方案传递Google Maps URL作为文本。

我想编码它，但我不认为我做得对。

let message = "View my current location at http://maps.google.com/?q=\(location.coordinate.latitude),\(location.coordinate.longitude)" 

var completewhatsappURLString = whatsappURL + message 

completewhatsappURLString = completewhatsappURLString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)! 

let completeURL = NSURL(string: completewhatsappURLString) 

Answer 1

let mapsURL = "comgooglemaps://?q=\(location.coordinate.latitude),\(location.coordinate.longitude)" 
let message = "View my current location at \(mapsURL)" as CFString 
let encodedString: String = String(CFURLCreateStringByAddingPercentEscapes(nil, message, nil, "!*'();:@&=+$,/?%#[]" as CFString, CFStringBuiltInEncodings.UTF8.rawValue)) 
let completewhatsappURLString = "whatsapp://send?text=" + encodedString 
let completeURL = NSURL(string: completewhatsappURLString) 
if (UIApplication.sharedApplication().canOpenURL(completeURL!)) { 
    UIApplication.sharedApplication().openURL(completeURL!) 
}
